asciilifeform: http://btcbase.org/log/2018-12-14#1880808 << on 2nd thought, 'no reported breaches' could mean 1 of 2 things !
a111: Logged on 2018-12-14 01:57 mircea_popescu: tbh, a recuperative scholarly series on sns would be most apt use of scholar's time.
asciilifeform: ( and not necessarily the 1 implied by commenter.. )
asciilifeform: in exactly same way that 'no reported thefts of gold from ft.knox' can mean 1 of 2 things.
asciilifeform: ( see also e.g. http://btcbase.org/log/2017-05-23#1660268 )
a111: Logged on 2017-05-23 02:41 asciilifeform: per dijkstra's 'testing can demonstrate the presence of bugs, but never their absence'

mircea_popescu: hey, wasn't proclaimed the golden veal. merely worth documenting.
mircea_popescu: since we're apparently all into bolixology or w/e you'd call it.
asciilifeform: mircea_popescu: believe or not, bolix aint even the least-gettable old/interesting comp
asciilifeform: e.g. xerox lispm is rarer still ( and had own merits, which i pieced together 100% from docs and surviving photos and won't even go into in depth because approx as questionable as archaeology of merv... )
asciilifeform: lotsa ancient artifacts are imho worth documenting. tricky bit is getting at the surviving crumbs.
mircea_popescu: sure.
asciilifeform: specifically in re 'iron built for reliability', 'tandem' was interesting. i dun expect to ever lay hands on 1 , tho
asciilifeform: even the old ibm irons have a few things to teach pc re redundant/votingcircuit scheme.
asciilifeform: ( i.e. box had multiple cpu that had to majority-agree re outcome of a cycle )
asciilifeform: reportedly items like this are being orbited , as cost-saving measure in place of ye olde saphire semiconductors. but there's ~nuffin publicly written re just how built.
asciilifeform: afaik all such schemes still suffer at least 1 'jesus bolt'.
asciilifeform: the win, when there is a win, is that you can make the jesusbolt 'stateless', i.e. if particle whacks it, it resets and retries the last cycle rather than going into metastable strange
asciilifeform distant from subj, cannot comment in detail re how well worx
phf: asciilifeform: i worked on tandem for a bit (known by then as HP NonStop), i appreciated the architecture, but entire software stack was cobol
phf: well, i appreciated it in theory, didn't have enough active drive to grok it, nor the necessary background
asciilifeform: oh hey interesting phf
phf: i still remember one of the cobol guys pulling out random bits from it on day one and going "i can just pull a bunch of things and it keeps working"
asciilifeform: btw phf i hate to repeat meself but am i ever gonna see that bolixgem you dug up, or will i have to get whole thing from xray
asciilifeform: ( the crate is slated to arrive tomorrow morning... )
phf: well, you'll still have to xray some, because i barely have anything on macivory, but i'll go over the scans this weekend. i actually have (miracle of miracles) free weekend coming up
asciilifeform: mircea_popescu: i'ma prolly end up xraying with own hands, i dun trust heathen derps with the jools
asciilifeform: phf: defo will have to xray, but thought 'oh hey possibly phf's material will give sumthing to correct against'
asciilifeform: what i could really use is some PAL/GAL src. if ever turns up. will make the affair go 9000x quicker.
asciilifeform: ( fwiw i still dunno if the bolix people set the lock bit in those things or not; possibly they didn't even )
asciilifeform: phf: my current plan for that box is , roughly, http://btcbase.org/log/2018-12-13#1880521
a111: Logged on 2018-12-13 18:53 asciilifeform: 1st logical step , on the magic day when asciilifeform has both pcb layout and GAL contents nailed down, will prolly be to make an exact physical copy of the board.
asciilifeform: ( i aint gonna stick to the period srams/drams, cuz that'd be simply dumb , each really belongs as 1 chip )
asciilifeform: ( and really dun need dram at all, the drams on the daughterboard are all connected through period auto-refresher ic that presents as a sram )
phf: so you want to make a replica that plugs into same hardware? i thought you'd want to do a fake mac harnes first?
phf: i.e. get macivory working outside of macintosh context
asciilifeform: phf: when thought about it, realized it was mistake : gotta find what the external-to-cpu logic on that thing actually does
asciilifeform: plus i'ma need ivorytron with direct probes on the cpu lines, and there aint any room for such a thing in the orig
phf: fair
phf: you know if ivory on macivory actually replaceable, the way it is on xl?
asciilifeform: ( actually 1st item will actually be to ditch the ancient scsi hdd and replace with solidstate. i'd hate to lose the box to platter rot )
asciilifeform: phf: socketed
asciilifeform: in fact damn near errything but the filter caps is socketed.
phf: yeah, the scsi/solidstate adapter exists, is actively used for "retro hardware"
asciilifeform: aha
asciilifeform: fortunately was quite gettable
asciilifeform: ( didn't exist ~5y ago when i last contemplated doing all of this )
feedbot: http://danielpbarron.com/2018/this-goes-against-all-human-rationality/ << Daniel P. Barron -- This goes against all human rationality.
asciilifeform: phf: i am thinking, instead of burning time on emulating 'nubus' and ancient crapple, when working (from mac-side pov) clone exists i'ma drive it directly via onboard ft2232hl or similar ( the mac-side src , i've had for yrs, and it's quite straightforward re what is done to the card; once i know what specifically happens on the card when nubus regs are written, may as well do it from pc directly to/from the ivory cpu via usb-to-5v-f
asciilifeform: ifo )
asciilifeform: a sort of anal feeding, if you will.
asciilifeform: the item can then be used as fairly compact instrument to probe behaviour of the chip vs. the old emulators.
asciilifeform: incidentally, i had potentially interesting notion: a modern-day digicam ccd, of e.g. 25 'megapixel', is just about dense enuff that one could take a meaningful xray of the ivory die, if one could be found that responds to xray..
asciilifeform: very much an open q tho.
asciilifeform: danielpbarron: full bore calvin, eh
asciilifeform: danielpbarron: plox to expand then, what do we get when we xor danielpbarron's no-free-wills with calvin
asciilifeform: also possibly i missed sumthing, but didn't danielpbarron schism from 'truechurch' ?
asciilifeform: ( or was it over some other doctrine )
asciilifeform: hm
asciilifeform: !#s darwinfish
a111: 1 result for "darwinfish", http://btcbase.org/log-search?q=darwinfish
asciilifeform: hrm
asciilifeform: could've sworn there was sumthing re a schism
asciilifeform bbl : off to maffs room for ~3rd~ rewrite of ch14...
asciilifeform: meanwhile, in phuctor q&a, http://p.bvulpes.com/pastes/1zcrs/?raw=true
asciilifeform: ( ben_vulpes : can haz logging back in #a plz ? )
asciilifeform: do i have to write own log bot nao on top of errything else ?
