asciilifeform: aha, and in ro you had z80
asciilifeform: http://btcbase.org/log/2016-04-10#1449707 << z80 had 64k addr space... ☝︎
asciilifeform: mircea_popescu: what did 'research' consist of there ? re-creating z80 ?
asciilifeform: mod6: that was support chipset, and a buncha z80
gernika: I'm just going to try out some z80 stuff. seems easier to use this than flashing eeproms.
asciilifeform: congrats! Z80 or 6502?
pete_dushenski: asciilifeform: as you do with z80!
assbot: The Anatomy of a Z80 Gate - Baltazar's Hacks ... ( http://bit.ly/20Pbubx )
asciilifeform: in unrelated, non-at-all-nyooz, but very spiffy: http://www.devic.us/hacks/anatomy-z80-gate
ascii_shmoocon: aaaand mining does not forgive 2nd-best 'z80 is enough for soviet motherland'-ism.
mircea_popescu: "Digital Group also offered a very wide range of hardware accessories. If it was available to computer users at the time, it was available to DG system owners, and usually first. A users group of the time reported (and I confirmed in conversation with Dr. Suding) that within two weeks of the release of the Zilog Z80 chip samples, Dr. Suding had finalized the design for the Digital Group Z80 processor card, and had work
mircea_popescu: the point, mind you, isn't even a "z80" planet. and yes i think that extremely unlikely.
ascii_butugychag: i would like, possibly more than most, to live in z80 planet.
jurov: the scenario "we will plod on z80 with 1 block/hr" calls for all of the existing hw to become suddenly unsuitable for mining
jurov: even without it, can z80 verify block in 10mins at all?
ascii_butugychag: fact is, you can't z80-mine on a planet with asic miners, etc
ascii_butugychag: on N z80.
jurov: mircea_popescu: i don't get the premise, you're able to grep gigabyte in 2s on z80?
ascii_butugychag: not so much of a difference in tech level required b/w z80 and pen
ascii_butugychag: there isn't really a collapse scenario where z80 remains
ascii_butugychag: i actually considered a parallel sov-z80 thing
assbot: Logged on 17-12-2015 06:17:18; punkman: http://www.symbos.de/preview.htm spiffy OS for z80
punkman: http://www.symbos.de/preview.htm spiffy OS for z80 ☟︎
pete_dushenski: asciilifeform: a luxury mr. z80-wisher-into-existence perhaps didn't have.
mircea_popescu: god damned it i'd rather be a z80/
asciilifeform: mircea_popescu: http://log.bitcoin-assets.com/?date=12-11-2015#1322328 << counterexamples are plentiful but they all involve zero-people-born-after-1985-or-so sorta thing. e.g., there are no z80 'conferences.' ☝︎
asciilifeform: ideally, a purpose that fit into 64kB of z80.
phf: perhaps http://retrodeluxe-msx.org, https://github.com/EtchedPixels/FUZIX alan cox thing, unix that targets z80, builds with pcc
ascii_field: also we don't need z80 for anything.
asciilifeform kicks crate of gdr z80
mircea_popescu: <davout> i can't wait for this to actually be a thing on TV once 3D printing is advanced enough << when i was a kid there was a 1hour midnight show that actually played z80 tapes
asciilifeform: they did without z80 even!
asciilifeform: and yes, cost is not a scalar. but as someone who actually buys things i am led to partially differentiate. i.e. if i personally need max cpu ~quantity~ for my personal bag of money, i will be buying z80.
mircea_popescu: when they can be compared, z80 loses. where they be meaningfully compared, common ground breaks down.
mircea_popescu: but back to our point of interest : your expectation that "z80" and "pentium" costs can be meaningfully compared breaks down.
mircea_popescu: go, put z80 on the list.
asciilifeform: re: previous thread: i get the hypothesis, but it falls apart re: z80 specifically. as it is... still made. and is about $5 in qty.
asciilifeform: z80 is absolutely cheaper.
mircea_popescu: pentium 3 is ACTUALLY cheaper to make than z80 ever was.
mircea_popescu: asciilifeform your argument will reduce to something like "making 1950s bachelite and fuel oil is '''cheaper''' than making diesel and wd40". this is equivalent to saying "z80 is cheaper to make than pentium 3". both are incorrect.
assbot: Logged on 09-10-2015 14:29:58; mircea_popescu: <asciilifeform> z80 box won't keep the blockchain ~only~ on account of slow instruction clocl. << peeps gotta understand that there's really nothing magical about longer numbers. if your computer can add bits, it can add 64 of them also. which is how we were doing arbitrary precision math on the z80, too.

asciilifeform: z80 box won't keep the blockchain ~only~ on account of slow instruction clocl.
pete_dushenski: ascii_field and where does z80 fit into this picture ?
ascii_field: go buy a soviet z80.
asciilifeform: mircea_popescu: microshit has not improved a single thing it touched, from z80 rom basic, xenix, msdos (yes), to this day
asciilifeform: mircea_popescu: i get that humint can be done entirely via 'hashishim' dissolved in planet at large, etc. but build me one single z80 this way.
ascii_field: or soviet z80 cpu of particular east german factory
assbot: Logged on 02-09-2015 13:47:14; asciilifeform: http://log.bitcoin-assets.com/?date=02-09-2015#1259538 << what 'its own' ? afaik there were z80, 6502, and a few pdp-compatibles. nothing 'own'.

asciilifeform: the z80 article has spiffy photos
mircea_popescu: it turns out that the sort of people who write good code write it in asm for a z80 or in c
asciilifeform: where is the 'coop' z80 ?
asciilifeform: no britney? welcome to 'univac', $1m half-z80.
asciilifeform: i had this whole 'trip' while holding a ru z80 in my hands and wondering why there is no more where it came from
asciilifeform: to bring back to concretes, ussr could have done something else with the manpower they sank into cloning pdp, z80
asciilifeform: z80
asciilifeform: http://log.bitcoin-assets.com/?date=02-08-2015#1221786 << no it is not 'a wonder' - it will build on a z80!!! cross-compiler, remember ? ☝︎
assbot: Logged on 26-07-2015 10:38:43; mircea_popescu: http://log.bitcoin-assets.com/?date=26-07-2015#1213025 << it never left, you know. it's still here. if you're willing to take z80 as "state of the art", the whole shebang is still here. problem is you want a different state of the art, because we actually need it, because z80 mined bitcoin can't survive in the field. and so...

mircea_popescu: 30gb, z80 cpu
ag3nt_zer0: z80
ascii_field: other thing is, items like z80 or rom of ~known vintage~ can be considered 'verifiable' in a weaker sense of the word
ascii_field idly wonders how big z80 would be if turned into discrete ttl
jurov: what russians did with z80 was not "reasonable expense"
jurov: z80 is closed source turd, too, no?
ascii_field: http://log.bitcoin-assets.com/?date=12-07-2015#1198964 << the 'open source chinese phones' thing is a complete snorefest. wake me up when street urchins can fab even a, e.g., z80 ☝︎
BingoBoingo: Seriously we need to storm an intel fab/fap and start pumping out Z80++/MIPS/and Scheme79 chips
BingoBoingo would really like box powered by 3GHz Z80 with ecc and 64 bit address space bolted on
asciilifeform: z80 never supported ecc
BingoBoingo: * asciilifeform has the same ill feeling an astronomer might have were 'seti' signal to appear << We've outgrown everything but Z80+ECC and somehow that is too slow
asciilifeform: (wallet on separate box, z80 if you like, etc)
asciilifeform: http://public.wsu.edu/~jackdoll/jak/comp/z80/z80p.htm << yes - computer!
assbot: Z80 Assembly ... ( http://bit.ly/1GAu9YH )
mircea_popescu: asciilifeform well z80 had a multiplier and iirc shifter
asciilifeform: z80-style, lacking multiplier & divider
asciilifeform: incl. bare z80
asciilifeform unpacks crate of east german z80 clones, counts, puts on shelf
BingoBoingo: Eventually such a shitquake will happen such that we start printing upclocked Z80 processors on a 7nm process
asciilifeform: http://log.bitcoin-assets.com/?date=17-06-2015#1165778 << find us another way to amortize the cost of making so much as a z80 ☝︎
asciilifeform: sometimes, literally (i'm getting a crate of east german z80 in the post a month or so from now)
mircea_popescu: and amic iirc was not actually a z80
BingoBoingo: Maybe some Z80 motherfucker detects the resistance of a lighter
ascii_field: hey, z80 is cheap!
ascii_field: as it is, i would not trust serious coin, were i to have any, to anything other than brainwallet operated with optical keyboard connected to soviet z80.
asciilifeform: -everybody- had a z80.
asciilifeform: http://log.bitcoin-assets.com/?date=09-06-2015#1157765 << that's a z80! not a cdp1802. ☝︎
asciilifeform: e.g., i have found at least five entirely separate sov. clones of z80
asciilifeform: it beat the shit out of its contemporaries (z80, 6502) for instruction-compactness
asciilifeform: (one of the best, z80, is -also- still with us. in current production, by the millions.)
asciilifeform: (zilog is still making z80, nominally pin-compatible with the 1976 variant, yes.)
Vexual: tell em its a z80
decimation: to the poor slav z80 coder, the 'naked' xeon has embarassingly rich resources
mircea_popescu: which was a z80 clone.
asciilifeform: decimation: c64 was not a z80 box
mircea_popescu: <decimation> he said that the yugoslav radio station would actually interrupt music broadcast to send - fsk encodings of z80 games << i had games i had downloaded off the natl tv station.
