gernika: I'm just going to try out some
z80 stuff. seems easier to use this than flashing eeproms.
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.
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?
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
pete_dushenski: asciilifeform: a luxury mr.
z80-wisher-into-existence perhaps didn't have.
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
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: 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.

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.

☟︎ pete_dushenski: ascii_field and where does
z80 fit into this picture ?
ascii_field: or soviet
z80 cpu of particular east german factory
mircea_popescu: it turns out that the sort of people who write good code write it in asm for a
z80 or in c

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...
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?
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
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
mircea_popescu: asciilifeform well
z80 had a multiplier and iirc shifter
BingoBoingo: Eventually such a shitquake will happen such that we start printing upclocked
Z80 processors on a 7nm process
BingoBoingo: Maybe some
Z80 motherfucker detects the resistance of a lighter
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.
decimation: to the poor slav
z80 coder, the 'naked' xeon has embarassingly rich resources
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.
