[04:21:14] <gloops> bit more work on the bandsaw today, when this final distraction is complete i can return to cnc work
[05:02:26] <XXCoder> gloops: lol thats fancy cnc machine
[05:06:51] <gloops> i only wanted to cut some log slices for signs, that quite a few people asked about, ended up taking 3 months to make a bandsaw lol
[05:07:24] <XXCoder> lol
[05:07:42] <XXCoder> serious though it might be foir very specific cnc thats rare? dunno
[05:07:48] <XXCoder> insane price for that thing

[05:36:07] <gloops> oh that router on ebay lol
[05:36:33] <XXCoder> or "router"
[05:36:44] <XXCoder> looks like just 2 screws motors
[05:41:53] <gloops> some square linear rails, leadscrews maybe salvageable - not for more than they cost new though
[05:42:03] <XXCoder> way more than new yeh
[05:42:35] <Loetmichel> link?
[05:43:05] <gloops> https://www.ebay.co.uk
[05:43:40] <XXCoder> im wrong
[05:43:43] <XXCoder> no motors
[05:43:50] <Loetmichel> $850 for THAT? ... good joke
[05:45:07] <gloops> id have it for parts, you could do something with the bits..ridiculous price though, start at 1p maybe go over £100
[05:45:49] <Loetmichel> leadscrews that hjave THAT much dirt on them are done for, rails the same. thats just a bit of scrap steel and alu now
[05:45:59] -!- Dave_Elec has quit [Ping timeout: 268 seconds]
[05:46:19] <Loetmichel> looks like it did a lot of stone milling
[05:46:47] <Loetmichel> maybe an engraver for tombstones or something from the looks of it
[05:46:49] -!- Dave_Elec has joined #linuxcnc
[05:46:50] <XXCoder> former engraver yeah
[05:47:01] <gloops> or been car spraying in the garage
[05:48:26] <gloops> https://www.ebay.co.uk
[05:48:50] <syyl> obviously not a single fuck given
[05:49:17] <syyl> if he just had blown of all the dust with compressed air, that would increase the chance for a good price
[05:49:40] <gloops> even that for 300 - no spindle, may as well put the other 200 in and get a new one, with spindle
[05:50:16] <SpeedEvil> Might even be fine, you can't even tell it's not soft plastic dust
[05:51:07] <gloops> never know that old one, might be top quality parts, good rails are expensive, but still way too much
[05:51:23] <XXCoder> wonder if thats case of "wife told me to sell and I dont want to" pricing
[05:51:54] <gloops> he probably got that out of skip, googled cnc router prices and though yipee
[05:53:11] <sensille> what is that short rail for on Z?

[05:59:55] <gloops> hmm not sure, looks like hes been engraving stone - maybe spring load travel?

[11:28:42] -!- Vitran has joined #linuxcnc
[11:34:25] <Vitran> I was hoping to get some info on the 7i64. What is the threshold voltage for the signal to be considered high/low and what is the hysteresis range. As far as I can tell, a signal above 5V will turn it on and the input signal can be up to 24V, but I do not know if it will turn on at 3.3V or what
[11:42:46] <cradek> the manual says 4v will turn the input on
[11:43:04] <cradek> pretty sure you should not count on it having hysteresis, it's just an opto
[11:58:12] <pcw_home> Yeah, very simple OPTO inputs, they drive a Schmitt trigger on the 7I64 but through the (always somewhat random) OPTO characteristics
[11:58:55] -!- ziper has joined #linuxcnc
[12:04:31] <pcw_home> I suspect 3.3V will turn it on since there is no shunt resistor on the 7I64 OPTOs but its near the threshold on the lowest gain bin OPTOs
[12:04:43] <fragalot> lol. local fuel station accidentally had one of their tanks filled with water rather than fuel
[12:04:52] <pcw_home> cheaper
[12:05:02] <fragalot> so far only 7 cars have been destroyed because of it freezing & bursting the lines
[12:05:10] <cradek> much better for the environment
[12:05:28] <fragalot> :)
[12:05:28] -!- Net| has quit [Ping timeout: 245 seconds]
[12:07:18] <pcw_home> seems like something that a specific hose connector type would eliminate ( there have been some very bad chemical explosions from similar mishaps )
[12:09:13] <gloops> water doesnt compress - if that is injected the engine will soon be kaput
[12:09:28] <fragalot> gloops: fuel doesn't compress either
[12:09:56] <fragalot> pcw_home: you'd think so. but at some point a tank got contaminated with water, and wound up at the fuel station
[12:10:06] <gloops> well dont come running to me with bent con rods
[12:11:37] <fragalot> \o/ score.

[13:21:42] <Roguish> modern steam punk engine,,,,,,,,,,,,,
[13:32:44] <fragalot> Roguish: ha. :-)
[13:39:49] <Net|> https://www.thingiverse.com
[13:40:50] <gregcnc> gloops water injection is as old as engines
[13:42:02] <gregcnc> just not in place of fuel
[13:43:45] <fragalot> gregcnc: depends on how hot said water is
[13:43:57] <gregcnc> hot?
[13:44:27] <fragalot> steam.
[13:44:38] <gregcnc> water injectionr, not steam injection
[13:45:18] <fragalot> same thing, just different temperature.
[13:45:36] <gregcnc> steam injection for internal combustion engine?
[13:46:20] <SpeedEvil> Six-cycle is a fun idea.
[13:46:31] <gregcnc> yeah they are all over the place
[13:46:31] <SpeedEvil> Delete cooling from IC engine add a steam stroke to remove heat.
[13:46:34] <fragalot> six cycle exists, used for diesel trains
[13:47:30] <fragalot> gregcnc: you inject the water into the engine to BECOME steam, which expands more than plain steam
[13:47:44] <gregcnc> so water or steam?
[13:47:53] <fragalot> both. starts as water, becomes steam.
[13:48:55] <SpeedEvil> https://en.wikipedia.org
[13:49:16] <gregcnc> I know about the crower, all the top automakers are using that design......
[13:52:59] <syyl_> fragalot, thanks, money came in

[14:03:14] <gregcnc> what does puppitast translat to?
[14:09:40] <ziper> does that actually work?
[14:10:18] <gregcnc> ??
[14:10:47] <ziper> the six-cycle water injection
[14:11:34] <sensille> gregcnc: dial test indicator?
[14:11:53] <gregcnc> I'm pretty sure testing proved it didn't
[14:21:26] <SpeedEvil> Who did the testing and if it was actually decent is another question.
[14:21:59] <ziper> it would be a 50 percent increase in friction, wouldn't it?
[14:22:02] <SpeedEvil> Landing rockets on their tails was not appreciably harder in 1990.
[14:22:41] <SpeedEvil> ziper: At least. But perhaps recovering some of the otherwise wasted exhaust heat.
[14:23:38] <ziper> How big does a steam turbine plant need to be to be competitive with diesel?
[14:23:56] -!- justanotheruser has quit [Quit: WeeChat 2.2]
[14:24:02] <SpeedEvil> IIRC big diesel beats steam.
[14:25:43] <ziper> yeah, now that i think about some of those ship engines

[14:29:08] * miss0r2 is doing his first 50/50 zink+nickel electroplating as we speak
[14:29:21] <miss0r2> Science, ladies and gentlemen!
[14:31:25] <gregcnc> https://paultan.org
[14:40:51] <fragalot> syyl_: Thank you. :-) they've already seen a fair amount of use. been scraping like a madman today..
[14:41:17] <fragalot> syyl_: for maintenance - do you just pop 'm into an ultrasonic cleaner every now & again, or do they require something "more"?
[14:41:28] <fragalot> miss0r2: how's it going?
[14:41:43] <SpeedEvil> 'This results in reducing fuel consumption by 15 percent, and an additional 14 horsepower and 15 lb-ft of torque for BMW’s inline-4 1.8 litre engine. And it doesn’t cost you anything as it is recycled from the exhaust gas heat.' - yeah - because weight is free and causes no parasitic drag.
[14:42:45] <gregcnc> getting the last few g/kWh isn't easy
[14:42:58] <SpeedEvil> Indeed.
[14:43:14] <fragalot> SpeedEvil: you can mitigate some of that by using the exhaust gasses as a bubbler under the hull to reduce drag
[14:43:22] <SpeedEvil> :)
[14:43:28] <fragalot> (no, really)
[14:43:43] <SpeedEvil> The above was a car
[14:43:56] <fragalot> Ah.
[14:46:33] <FinboySlick> Not complex enough. Use waste exhaust/engine heat to drive a stirling engine.
[14:47:19] <FinboySlick> I think there were already some attempts at this.
[14:47:30] <SpeedEvil> yeah
[14:47:59] <SpeedEvil> the novel bit about the six-cycle was being able to dump the exhaust heat exchanger.
[14:48:13] <SpeedEvil> And not need an extra steam cylinder
[14:48:17] <SpeedEvil> The Crower anyway
[14:48:29] <SpeedEvil> the BMW one has a steam cylinder.
[14:49:05] <FinboySlick> Yeah, but you're still carrying water around, no?
[14:49:14] <SpeedEvil> Indeed.
[14:50:13] <fragalot> SpeedEvil: there are also ... what's that electronic equivalent of the stirling engine called again
[14:50:16] <fragalot> peltier
[14:50:39] <SpeedEvil> Unfortunately inefficient. 10% or so
[14:50:42] <gregcnc> peltier efficiency is pretty bad
[14:50:49] <SpeedEvil> and that also needs a large cooler
[14:51:10] <fragalot> yeah but it's still like 0.05% more than not regaining anything.
[14:51:21] <fragalot> and therefore TOTALLY worth it
[14:51:22] <FinboySlick> SpeedEvil: Well, on a car if you had efficient peltier you could always use the body or an underplate as a giant cooler.
[14:51:22] <fragalot> :D
[14:51:45] <gregcnc> not cheap or durable
[14:51:46] <fragalot> FinboySlick: or the existing coolant circuit?
[14:52:47] <FinboySlick> fragalot: I guess, though I think peltier sink temperature versus ideal engine run temperature might be difficult to harmonize.
[14:53:39] <fragalot> FinboySlick: well one end is on the host exhaust, the other is at ~90°C -- there should be a decent temperature differential there
[14:54:48] <FinboySlick> I was thinking efficiency maximization where you'd essentially insulate the entire block so that all waste heat would go to the peltier/stirling recuperator.
[14:56:10] <fragalot> now /THAT/ would be hard :-)
[14:57:07] <FinboySlick> Since you'd probably have a very narrow power/efficiency range. Might as well put all that work into fuel cells.
[14:57:42] <FinboySlick> I remember the Ballard days ;)
[14:58:27] <FinboySlick> Rumor has it they had their breakthrough using some Glad plastic bags (or something very similar) as a barrier. I don't think they ever revealed what it was though.
[15:00:32] <fragalot> I mean.. you are proposing to dump ~170kW of heat (assuming ALL inefficiency is counted as heat) through that poor little peltier
[15:00:54] <fragalot> (assuming my car, at ~36% effiency)
[15:01:08] <gregcnc> 50% of waste goes out the exhaust
[15:01:10] <FinboySlick> I was assuming a spherical cow in a vacuum.
[15:01:50] <FinboySlick> (that is, an efficient heat recuperation tech)
[15:06:37] <ziper> How does a bubbler under the hull reduce drag?
[15:06:43] -!- _unreal_ has quit [Read error: Connection reset by peer]
[15:06:55] <ziper> wouldnt the reduced density cause the hull to just sit lower in the water?
[15:07:26] <fragalot> it would, but - assuming that one YT video I saw is true - that is offset by the reduced friction
[15:08:01] <ziper> is it for displacement or planing hulls?
[15:08:08] -!- _unreal_ has joined #linuxcnc
[15:08:15] <fragalot> they showcased it on an oil freighter
[15:08:32] <gregcnc> it's not a new idea.

[15:08:48] <fragalot> the video paired it with rotary pillar sails

[15:11:23] <FinboySlick> mach2 oil tanker incoming.
[15:11:51] <ziper> hydrofoil tanker
[15:11:56] <gregcnc> yes
[15:12:08] <fragalot> FinboySlick: should be fun watching it crash into the pier
[15:12:27] <FinboySlick> I'm pretty sure it'd make it a few km past the pier.
[15:13:06] <fragalot> which part
[15:13:37] <FinboySlick> If it made it through mach2 in one piece, probably most of them.
[15:14:00] <_unreal_> figures I just got back been out most of the day shopping and stuff.. got the supplies I need so i can build the damn mold... and now its raining like hell outside
[15:14:14] <_unreal_> @%@#$ me
[15:15:00] <_unreal_> no matter how hard I tried I couldnt find my release wax for fiberglass layup... so I just went all the way to the FRP shop to get some.... get back now its raining.... yep
[15:15:03] <FinboySlick> _unreal_: Somebody figured out a buffer overflow in xchat and just hacked you with the channel list ;)

[15:20:46] <FinboySlick> Haha, just computed, that tanker (assuming a fairly average-sized one) would be about 4.6*10^14 joules of kinetic energy.
[15:20:53] <_unreal_> just to give you an idea of my area.... if you want to. google boca raton, as far west as you can go between glades rd/pallmetto rd... I'm in that general area
[15:21:51] <FinboySlick> A bit more than the median yield of modern nuclear weapons.
[15:22:23] <_unreal_> well I guess its time to have my last beer.
[15:22:49] <FinboySlick> _unreal_: Abom79 country.
[15:22:59] <_unreal_> ?
[15:23:02] <_unreal_> is that florida
[15:23:06] <ziper> that city is a testament to mans arrogance
[15:23:19] <FinboySlick> _unreal_: Yes. Beware the large man with a wrench.
[15:24:19] <ziper> suburbs are the lead pipes of the american empire
[15:25:10] <FinboySlick> And lead pipes are the best murder weapon in Clue.
[15:25:20] <fragalot> miss0r2: most common issue appears to be that "the part wasn't clean enough"
[15:25:43] <miss0r2> hmm. I guess that is an option, though, I *DID* etch it
[15:27:44] <_unreal_> speaking of etching... SOOOO pissed at my self.... I spent hours breadboarding to build a motor controller... I had 3, dont know what happend to the 3rd one that was 99% done just missing a few resistors......
[15:28:07] <_unreal_> so rebuilt one from scratch..... got the missing resistors for everything
[15:29:32] <_unreal_> and yesterday. I was doing a bunch of cleaning I had forgotten I had purchased high quality (from goodwill go figure) laminator... I could have printed a new board laminated it and etched it. BUT NO......... I said to my self. well shit I dont have an iron guess I wont be etching... "" I KNOW I'LL BREAD BOARD IT!""
[15:30:22] <_unreal_> moving stuff in the office came across it buried....... !!!!!! is.. that a..... ohhhhhh WTF..........

[15:31:27] <_unreal_> its one of those laminators that can take items upto 1/8th thick....
[15:31:43] <FinboySlick> I'd love to understand electronics enough to build things like motor controllers.
[15:31:54] Inline is now known as oleo
[15:32:02] <_unreal_> FinboySlick, its more or less just following schematics
[15:32:34] <FinboySlick> Well, that I could do but I wouldn't really understand what I'm doing.
[15:32:40] <_unreal_> trust me i DONT know all the laws of ohms etc..... I know enough to find online calculators etc... or bother people in the ##electronics channel :)
[15:32:55] oleo is now known as Inline
[15:33:10] <FinboySlick> Well, I know the V=RI one.
[15:34:01] <FinboySlick> But the impedance and AC stuff really hurts my brain.
[15:34:29] <_unreal_> FinboySlick, I just got a 3com audrey today in the mail. got it off ebay for $19 USD +ship.... thats OMG especially for what it is... granted its 18+ years old now but they were killing me when they where new wanted one in the worst way... but they were selling for $500 then....
[15:34:46] <_unreal_> now its equal to like a pentium 1 166mhz
[15:35:13] <_unreal_> but that doesnt bother me any :) I have an other device that has the exact same cpu hardware in it.... but I can boot to different OS's
[15:35:41] <_unreal_> so I'm wondering if I can do some research and figure out what no one else could on how to get the thing to boot other os's
[15:36:18] <_unreal_> I'll laugh if I do. because no one else has.... sadly the best source for info on the @#$# damn things and may others is now gone only archive.org has it... linux-hacker.net :(
[15:36:27] <_unreal_> may she rest in piece
[15:37:49] <renesis> wtf is that thing unreal
[15:40:40] <Vitran> I have small massive news. I got the X axis and Z axis working on the lathe today! It is a Hardinge Superslant. Been a 3 year project
[15:41:27] <_unreal_> ren its like the iopener
[15:41:52] <_unreal_> same idea different x86 cpu
[15:42:37] <FinboySlick> Vitran: Congrats on that. It's a pretty neat piece of hardware.
[15:44:13] <ziper> how old are the PCs you guys run linux cnc on?
[15:44:29] <ziper> ancient, just obsolete, or current?
[15:44:30] <JT-Shop> Vitran: nice, does the super slant have the dual turrets?

[16:23:19] <gregcnc> ziper ancient, P3 900, 512mB, but it's pretty much maxed
[16:24:22] <Vitran> Back from food. It has a turret and tailstock. Turret and tailstock have 8 heads
[16:24:53] <gregcnc> twin turret tehn?
[16:26:21] <gregcnc> oh had to check, no X on the tailstock. what year is that?
[16:27:31] <JT-Shop2> Vitran: you got the turret working?

[16:29:03] <Vitran> <JT-Shop2> Not sure yet. It has been resting on a block of wood. I do know that the upper turret is leaking air like mad. Not sure why, but I do know it was doing that before
[16:29:13] <Vitran> I believe it was a broken o ring
[16:31:29] <JT-Shop2> yea my chnc turret and collet closer leak air at a huge rate even with all new o-rings and quad rings

[21:12:31] <norias> oi
[21:12:37] <norias> trying to learn how cnc works
[21:12:49] <norias> i got a book called "automatic control systems"
[21:13:29] <norias> should eventually get to PID controllers there
[21:17:35] <_unreal_> norias, what are you trying to learn?
[21:17:49] <norias> cnc systems from the ground up
[21:18:05] <_unreal_> ok but WHAT are you trying to learn
[21:18:13] <_unreal_> the hardware? the software
[21:18:20] <norias> yes
[21:18:25] <norias> :)
[21:18:38] <Rab> norias, commercial systems or DIY methods?
[21:18:46] <norias> Rab: commercial
[21:18:49] <_unreal_> That was going to be my next Q
[21:18:56] <norias> but i think i should have a passing familiarity of DIY
[21:19:10] <norias> i'm a machinist, by trade
[21:19:12] <norias> btw
[21:19:18] <_unreal_> norias, do you HAVE a commercial one or are you planning on working for a company with said machine and wwhich one?
[21:19:27] <_unreal_> they are all different in regards to how to control them
[21:19:28] <norias> so, the mechanical components are rather well known to me
[21:19:48] <norias> _unreal_: i'm sticking with mills, for now
[21:20:00] <_unreal_> palm to face..... ok then you are really only interested in the control/software side
[21:20:06] <norias> no
[21:20:08] <Rab> norias, here's a great resource: https://www.cnczone.com
[21:20:14] <_unreal_> :)
[21:20:14] <norias> Rab: thanks
[21:20:25] <_unreal_> hay rab I need to post some photos
[21:20:35] <Rab> _unreal_, orly
[21:20:38] <_unreal_> I got my splash mold done finally for my RPI lcd enclosure
[21:20:40] <norias> i'm going to start with how many windings of what sort of wire
[21:20:45] <norias> how that affects the motors
[21:20:55] <_unreal_> O.o
[21:20:56] <norias> through all the controls and software
[21:20:58] <_unreal_> wtf
[21:21:06] <norias> that's how i do things
[21:21:11] <norias> it works for me
[21:21:16] <_unreal_> why?
[21:21:23] <norias> i might want to make one
[21:21:30] <_unreal_> its called spec's
[21:21:37] <norias> if nothing else, everything i've learn so far has made me a better machinist
[21:21:49] <Rab> norias, as a machinist you may already be familiar with PM, but just in case: https://www.practicalmachinist.com
[21:21:52] <_unreal_> motors ounce inch rating per voltage etc....
[21:21:59] <norias> Rab: I dig PM
[21:22:20] <norias> _unreal_: what do you have against learning? :)
[21:22:59] <_unreal_> I'm not knocking it. just saying the useful gain of that knowlage is limited in regads to application
[21:23:25] <norias> eh, we'll see
[21:23:30] <Rab> Scroll down, lots of forums specific to various commercial controls/mfgs. Obviously forums don't make for a clear overview, but they're a great resource for chasing down esoteric details of interest.
[21:23:50] <_unreal_> including building. "specs" tell you the very details needed for build a machine using said motors.
[21:24:11] <_unreal_> rab somewhere in there are photos of the first machine I ever built
[21:24:14] <_unreal_> cnczone.com
[21:24:23] <_unreal_> freaking like 18 years ago
[21:24:42] <_unreal_> cnczone.com was very small back then
[21:24:59] <norias> i any of you ever read any of the Moore books?
[21:25:25] <Rab> norias, I don't think so.
[21:25:25] <norias> like "Foundations of Mechanical Accuracy" by Wayne R. Moore?
[21:25:35] <_unreal_> rab I just picked up a 3com audrey
[21:25:44] <Rab> Heard good things about that particular book, though.
[21:25:49] <norias> it's great
[21:25:51] <norias> good fun
[21:26:37] <norias> those guys were detail oriented
[21:26:58] <Rab> _unreal_, I hope you're having fun with it, but I have a horror of that old stuff. I used to have a bunch of iOpeners which were about the same thing, made many hardware modz.
[21:27:17] <Rab> Sent them all to e-waste.
[21:27:41] <_unreal_> Rab, get this
[21:27:44] <_unreal_> !!!!!
[21:27:51] <_unreal_> ewaste
[21:27:55] <_unreal_> you bastard
[21:28:08] <_unreal_> should have sent them to ebay waste
[21:28:16] <Rab> In Texas we say: basura
[21:28:23] <Rab> Ain't nobody got time for that
[21:28:31] <_unreal_> in anycase get this
[21:28:39] <_unreal_> so the 3com audrey
[21:28:50] <Rab> Plus for cheap or free you can get an old Stinkpad or other quality laptop that's 1000x better.
[21:28:54] <_unreal_> did you ever do anything with it?
[21:29:09] <Rab> _unreal_, nope, I've not seen one in person.
[21:29:14] <_unreal_> ok
[21:29:19] <_unreal_> in anycase
[21:29:29] <_unreal_> main problem with it is that is was lacking a "bios"
[21:29:40] <_unreal_> has a 16MB flashrom
[21:30:03] <_unreal_> flash/bios combo I guess
[21:30:15] <_unreal_> but it has the foot print on the motherboard for BIOS
[21:30:21] <_unreal_> just missing the header
[21:30:54] <_unreal_> so i also have an other device called the eznet 200. has the exact same hardware inside. same cpu chipsets EVERYTHING is the same 99%
[21:31:01] <_unreal_> but the eznet has a bios chip
[21:32:50] <_unreal_> I just ordered some plcc32 sockets, and compatable eeprom's (bios chips). When the get here I'm going to try dropping one of these chips into the audrey
[21:32:55] <_unreal_> I have a feeling it will boot
[21:33:41] <_unreal_> rab the audrey has a w49f002up12b chip in it
[21:37:34] <_unreal_> ?
[21:38:09] <Rab> _unreal_, are you getting a chip with the Audrey bios pre-flashed?
[21:39:53] <_unreal_> https://drive.google.com
[21:39:59] <_unreal_> there IS no chip
[21:40:15] <_unreal_> was never released, and linux-hacker.net is gone so I dont know
[21:40:22] <_unreal_> I dont know if anyone ever made a bios for it
[21:40:37] <Rab> I know, but you're going to populate the pads with a socket and blank bios chip? What will that do?
[21:40:41] <_unreal_> but as far as I can tell the companies that made the 2 devices used the same refrence design 99% the same
[21:40:51] <_unreal_> not a blank bios
[21:41:02] <_unreal_> I'm going to put a copy of the bios from the other system the eznet 200
[21:41:18] <_unreal_> they are 99% the same on the inside. a
[21:41:44] <_unreal_> all of the chips are the same. same cpu, same north or south bridge what ever it is. same super I/O chip and few others
[21:41:53] <_unreal_> even the ram chips are the same between the 2
[21:42:09] <_unreal_> wow I typed that out fast :)
[21:42:50] <_unreal_> So ya I'm going to take a copy of the bios for the eznet 200 put it on one of these 2 chips I just ordered. then for haha's put that chip in my eznet 200
[21:43:00] -!- veek has joined #linuxcnc
[21:43:25] <_unreal_> if it post's, then I'm going to take that chip and put it in the audrey when I get the socket for the plcc32 done if not already by then.
[21:44:12] <_unreal_> the only thing I dont know at this point is the fact that is has that other chip
[21:44:27] <_unreal_> w49f002up12b
[21:45:02] <_unreal_> What I am wondering is how to read that mofo... see if I can get a copy of the "bios" from it
[21:46:15] <_unreal_> There is a little header near both the bios chip and that chip existing chip the w49xxx one have not looked closely yet but if the header goes those one or both of those then its likely an ICSP
[21:46:39] <_unreal_> What do you think of my splashmold?
[21:46:58] <_unreal_> wholy shit I type a lot
