[00:00:17] <rue_house> k
[00:00:20] <katsmeow> thi is sunday
[00:00:27] <rue_house> I put your digits and the box in the livingroom
[00:00:40] <rue_house> I'm planning to ship the current 2 spools and the digits
[00:01:03] <rue_house> should help with shipping weight of other spools
[00:01:48] <katsmeow> should you make a 3rd first, so you have one bird in the paw as you make the 4th etc ones ?
[00:02:14] <rue_house> I did the second just by the drawings
[00:02:37] <katsmeow> you did the first one that way also
[00:02:46] <rue_house> I have never made tho things on the lathe so much the same
[00:02:52] <rue_house> two
[00:03:38] <rue_house> I'm getting sleepy
[00:03:41] <rue_house> perfect timing
[00:05:01] <katsmeow> i seem to be out of water,, brb
[00:10:00] <rue_shop3> 8|
[00:11:32] <katsmeow> bak
[00:16:46] <katsmeow> http://www.s100computers.com/Cards%20For%20Sale.htm
[00:19:15] <rue_house> why is the keybaord controller so many z80 io chips?
[00:19:25] <rue_house> no its a whole z80 system
[00:20:00] <katsmeow> i didn't do it
[00:20:12] <rue_house> inteh day, they used a 8041 ...
[00:21:22] * katsmeow used a lot of 8031/35/48,,, forgot almost everything now tho
[00:21:45] <rue_house> the z80 didn't use support chips, why are there so many on the cpu baord?
[00:21:54] <katsmeow> owned puters with z80,6510,6502,8086 in them
[00:22:07] <rue_house> I'd love to get into the 8035/48
[00:22:17] <katsmeow> since when? zilog made tons of support chips for z80
[00:22:18] <rue_house> no time
[00:22:25] <rue_house> since '85
[00:22:27] <rue_house> ish
[00:22:57] <rue_house> yea, but the z80 didn't need ...42 support chips.
[00:23:12] <katsmeow> true, just a handfull of dip-40s
[00:23:58] <katsmeow> i dunno thio, the ZX80 had a lot of ssi chips (dip14, dip16) in it, more than the vic20 or C64
[00:24:25] <rue_house> 8086 board?
[00:24:35] <rue_house> and the io map works for msdos?!
[00:25:02] <rue_house> oooh, with support board
[00:25:15] <rue_house> that motherbaord sosn't ahve enough slots to make even a simple machine
[00:25:43] <katsmeow> the s-100 buss it plugs into supplies the where to plug in more cards
[00:26:27] <rue_house> yea
[00:26:36] <rue_house> you need lots of cards for this thing
[00:27:41] <rue_house> hahah parallel ports made of 8212
[00:27:48] <katsmeow> well, they fight to keep it the 1980's, using no PLA/GAL, using mfm drives, or at least nothing over 8 GB, using static rams, no dynamics, 10Mhz is the fastest cpu, etc etc
[00:28:13] <rue_house> ... 286 board...
[00:28:27] <rue_house> iirc the 8212 was replaced byt eh 74274
[00:28:33] <rue_house> 374
[00:28:39] <katsmeow> 138
[00:28:58] <katsmeow> wasn't the 8212 a decoder?
[00:29:14] <rue_house> bus buffer
[00:29:24] <rue_house> latch?
[00:29:43] <katsmeow> oh, ,,, forgot almost everything now tho
[00:30:19] <rue_house> the 8080 needed them to drive the bus
[00:30:27] <rue_house> they integrated them into the z80
[00:30:58] <katsmeow> yeas, advertising the cpu had a whole 1 ma pullup capacitry, lol
[00:32:13] <rue_house> I think the isa to s100 bus converter baord says it all, its the s100 bus that is adding all the complexity
[00:33:07] <katsmeow> it's 100 pins in parallel, how is it complex?
[00:33:31] <rue_house> to translate it to isa, they need 20+ chips
[00:33:58] <katsmeow> that's just dumb timing on the buss when they wanna do isa
[00:34:18] <rue_house> and the bus cant handle memory refresh or something all they use is static
[00:34:45] <katsmeow> memory refresh should not be on the buss anyhow
[00:35:03] <rue_house> I realized that the old cnc prolly uses brensham cause the processor on it wont have an fpu
[00:35:06] <katsmeow> all ram cards should *look* static
[00:35:12] <rue_house> erm alu
[00:38:13] <rue_house> math co-processor
[00:39:32] <katsmeow> weitek
[00:40:17] * katsmeow looks tired, worn out, AND sleepy
[00:41:12] <rue_house> do welding today?
[00:41:14] <katsmeow> could just glue a raspi to each s-100 proto pcb, and be done with it
[00:41:37] <katsmeow> no, moved trees/brush i cut down yesterday
[00:42:49] * katsmeow wavers gnites
[00:43:01] <rue_house> night
[22:03:58] <rue_shop3> hahah
[22:04:12] <rue_shop3> the wood I put the peice on shrunk cause of the dry shop, came loose from the clamps
[22:04:15] <rue_shop3> *sigh*
[22:04:28] <katsmeow> what peice ?
[22:09:50] <rue_shop3> part of a can holder
[22:09:59] <rue_shop3> its a 3mm plate mill-out job
[22:10:09] <rue_shop3> moved all around when the bit hit it
[22:11:55] <rue_shop3> ok thats going, whats the second thing I'm supposed to be working on today
[22:14:16] <rue_shop3> "take apart deck stuff"
[23:03:40] <rue_shop3> ok I finished taking apart _1_ page feeder
[23:06:19] <Jymmm> copier?
[23:09:11] <rue_shop3> LOTS of them
[23:09:18] <rue_shop3> you should have seen my deck
[23:09:24] <rue_shop3> its under there somewhere
[23:09:34] <Jymmm> lol
[23:09:46] <rue_shop3> its big, I have a big deck
[23:09:53] <Tom_itx> more junk for the pile?
[23:09:55] <Jymmm> I molten some salt today, perlite makes an EXCELLENT thermal insulator for high temps
[23:10:36] <Jymmm> Inside 1100F+, outside 120F, withone inch wall of perlite
[23:11:57] <rue_shop3> https://www.youtube.com/watch?v=hkmeoYKYctw
[23:12:08] <rue_shop3> I have a big deck, and I'll get it back one day
[23:13:49] <Jymmm> http://imgur.com/a/1GpiR
[23:14:31] <rue_shop3> thats not salt is it?
[23:14:48] <Jymmm> the red stuff is salt
[23:14:56] <Jymmm> the white stuff is perlite
[23:14:58] <rue_shop3> sodium chloride salt?
[23:15:06] <Jymmm> table salt
[23:15:15] <rue_shop3> yea sodium chloride
[23:15:38] <rue_shop3> it takes a LOT of heat to melt salt, how the hell did the paint can stay in tact?
[23:15:53] <rue_shop3> b) why were you melting salt?
[23:15:57] <rue_shop3> electrolysis?
[23:16:08] <Jymmm> The outter can is a coffee can, the inner is a progresso soup can
[23:16:19] <rue_shop3> k, scale is off, but still
[23:16:24] <rue_shop3> how did it stay in tact?
[23:16:45] <Jymmm> perlite is THAT good of a high temp insulator
[23:17:29] <Jymmm> I didn't use a binder (this time), just was a test of molting salt
[23:17:55] <Jymmm> I have been testing mortar and clay as binders though
[23:18:38] <rue_shop3> but the steel comes apart
[23:18:48] <Jymmm> I wanted to see how well salt works as a thermal mass
[23:19:03] <rue_shop3> not as good as water
[23:19:08] <rue_shop3> in a state change
[23:19:25] <Jymmm> water boils/evamporates
[23:19:56] <rue_shop3> the two things that have the most theremal mass are
[23:20:04] <rue_shop3> liquid hydrogen
[23:20:06] <rue_shop3> and water
[23:20:16] <Jymmm> silicon
[23:20:19] <rue_shop3> I think its hydrogen
[23:20:29] <rue_shop3> water is second tho
[23:20:34] <Jymmm> siicon is rightt after hydrogen
[23:20:37] <katsmeow> copper
[23:20:54] <Jymmm> http://www.engineeringtoolbox.com/specific-heat-solids-d_154.html
[23:20:55] <rue_shop3> no, thermal ... whats it called
[23:21:01] <rue_shop3> what!?
[23:21:02] <Jymmm> specific heat
[23:21:22] <Jymmm> rue_shop3:
http://www.engineeringtoolbox.com/specific-heat-solids-d_154.html
[23:21:26] <Jymmm> bah
[23:21:34] <Jymmm> rue_shop3:
http://www.sciencedirect.com/science/article/pii/S0360544216304546
[23:21:41] <rue_shop3> well, it dosn't matter really, if you go thu a state change, you store WAY more energy
[23:22:10] <rue_shop3> filling pingpong balls with wax and putting them in a storage tank is a great way to boost the storage level
[23:22:19] <rue_shop3> set the wax to melt at the right temp
[23:22:47] <Jymmm> I'm pondering firebox / salt / wax
[23:23:11] <rue_shop3> the salt will eat everything metal
[23:23:40] <Jymmm> Yeah, I'm still trying to source silcon
[23:23:58] <katsmeow> gauber's salt
[23:24:35] <katsmeow> or however it's spelle
[23:24:37] <katsmeow> d
[23:24:49] <Jymmm> Sodium sulfate
[23:24:57] <katsmeow> ok
[23:25:10] <Jymmm> I can't find silicon powder thugh
[23:25:20] <Jymmm> except indian/china
[23:25:24] * rue_shop3 giggles
[23:25:35] * rue_shop3 whispers 'sand' to kat
[23:25:54] <rue_shop3> er
[23:25:58] <katsmeow> Melting point 884 °C (1,623 °F; 1,157 K) (anhydrous)
[23:25:59] <katsmeow> 32.38 °C (decahydrate)
[23:26:23] <katsmeow> sand - quartz - silica
[23:26:41] <rue_shop3> yea SiO2
[23:26:58] * rue_shop3 flags 'not crazy'
[23:27:05] <Jymmm> https://en.wikipedia.org/wiki/Silicon
[23:27:06] <katsmeow> Two thirds of the world's production of the decahydrate (Glauber's salt) is from the natural mineral form mirabilite, for example as found in lake beds in southern Saskatchewan.
[23:27:15] <Jymmm> Si, not SiO2
[23:30:04] <Jymmm> rue_shop3: but I might just use sand (or clay) due to it's availability
[23:31:25] <Jymmm> Interesting, cement, dry has a high specific heat. I wonder if that's powder form, or once set?
[23:32:02] <rue_shop3> Si2?
[23:32:09] <rue_shop3> whats Si when its not SIO2
[23:32:14] <rue_shop3> SiO2
[23:32:16] <rue_shop3> Si2?
[23:32:53] <Jymmm> this

[23:33:16] <rue_shop3> damn its 9already
[23:34:10] <katsmeow> 11already here
[23:35:18] <katsmeow> TIL there is a town called Cle Elum , zip code 98922
[23:35:38] <rue_shop3> I'd better get soemthing done befroe you time catches up to m
[23:35:42] <rue_shop3> e
[23:58:38] <rue_shop3> ok, thats 2 printer trays
[23:58:50] <rue_shop3> that cleared about 2 cubic feet of deck space,
[23:59:09] <rue_shop3> yeilded about 8lbs of goodies
[23:59:37] <rue_shop3> generated about 10 lbs of scrap metal
[23:59:40] <katsmeow> to cnc the lathe, so it can remember the moves you make on it, and repeat them?
[23:59:52] <rue_shop3> and generated about 3 cubic feet of scrap plastic
