asciilifeform: that 6502, is a 8 micron ic, almost half century old nao
asciilifeform: SeanRiddle: were you ever able to actually re a circuit from your photos ?
asciilifeform: it is my understanding that any dust at all is a problem for this job
asciilifeform: SeanRiddle: is this the orig form of the https://upload.wikimedia.org/wikipedia/commons/4/44/Oki_m6283_metal.jpg item ? with dust & all ?
asciilifeform: ( what it also does, is prevent from loading the pic in sections, which is annoying )
asciilifeform: why's it a jpg anyway, wouldn't this introduce artifacts ?
asciilifeform: 'gimp' chokes.
asciilifeform sadly does not yet have with what to actually look at the photo
asciilifeform: notbad
asciilifeform: i had that thing, but it certainly didn't take 43k x 43k photos. didja stitch'em ?
asciilifeform tries to find sumthing that'll display that thing without choking ☟︎
asciilifeform: SeanRiddle: what sorta camera didja use ?
asciilifeform: ~600MB notbad
asciilifeform looks
asciilifeform: wb SeanRiddle
asciilifeform: iirc i posted my solver, but for somereason cannot find in log, so will repost, http://p.bvulpes.com/pastes/4TeLb/?raw=true
asciilifeform: mircea_popescu: was this the http://www.loper-os.org/pub/mp.gif thing ? ☟︎
asciilifeform: it's a good try, but i dunno that this is usable for re.
asciilifeform: ( also seems to have dirt, which is problem, cuz 1 speck of shit can cover several 100 transistor at this density -- not even speaking of moar recent micronages )
asciilifeform: http://btcbase.org/log/2018-11-30#1876486 >> notbad, e.g. https://upload.wikimedia.org/wikipedia/commons/4/44/Oki_m6283_metal.jpg , but still can't see individual transistors there, unless i'm missing sumthing ☝︎
asciilifeform: in earlier days there were also folx stuffing strings into block hdrs, but dunno if this is still in fashion, and at any rate no longer doable if you aint chinese, to 1st approx
asciilifeform has personally used this mechanism for remote control of... autonomous machinery
asciilifeform: costs whatever the miner fee is, plus epsilon for payload ( most of the current chinese won't mine a 0-summing tx iirc )
asciilifeform: but sure can stuff in whatever bytes, iirc addr decoder barfing dun invalidate a tx , classically
asciilifeform: i vaguely recall this gag
asciilifeform: hey didn't sumbody stuff in 'goldbug' virus from 1993 , and thereby trigger microshit's av
asciilifeform: ( then can encode txt as dest addrs )
asciilifeform: it's easier if you dun intend to recirculate the coinz.
asciilifeform: ( it wasn't obv from the link )
asciilifeform: was curious which one was used
asciilifeform: mircea_popescu: there's several ways to 'add text' , aha , http://www.loper-os.org/?p=1490
asciilifeform: elderly academics who can barely hold up cup of tea, and buncha quasi-literate young folx ( see infamous http://btcbase.org/log/2013-12-01#400666 ) to wait on'em ☝︎
asciilifeform: current mit is a kind of nursing home, as i gather
asciilifeform: ( not esp surprising tho )
asciilifeform: dun appear to be lispm-related, sadly
asciilifeform: ah
asciilifeform: ( somewhere on my hdd, there's a photo of shrobe walking across a stage holding up a 3620 , the kind in http://www.loper-os.org/?p=51 , in his hands, 'looksy, first 'portable' bolix' )
asciilifeform: iirc he went into medicine after bolix folded
asciilifeform: always worth a shot
asciilifeform: amberglint: he's 1 of the folx i've tried writing to, in past yrs, perhaps you'll have better luck than i
asciilifeform: or is this 1 of those heathen 'blockchain info' 'append note to your tx' promisetronic thingies
asciilifeform: yes, but ~where in the tx~ does the text live
asciilifeform: Mocky: i dun see where 'embedded' tho
asciilifeform: amberglint: pdp10 is approx as interesting as nintendo tho
asciilifeform: could have the crown jewels, or not, nobodyknows.
asciilifeform: nfi
asciilifeform: had 0 to do with design.
asciilifeform: mircea_popescu: house, was fulla iron, old moldy cards, hdds, consoles. dks was/is a repairman, afaik mechanical engineer orig by trade .
asciilifeform: ( moldy tapes also )
asciilifeform: it is on moldy papers. and iirc phf even has been to where.
asciilifeform: ( he condescended to give asciilifeform a keyboard pinout, and had to 'go to warehouse' to get )
asciilifeform: mircea_popescu: dks ? made pretty convincing case that they aint at his house ( but whoknows )
asciilifeform: amberglint: afaik nobody's found'em yet
asciilifeform: http://www.loper-os.org/pub/ns-cherry.pdf mirrored.
asciilifeform: ty amberglint
asciilifeform: amberglint: they're pretty sweet 4core arm64 boxen; i assembled and engentoo'd with own hand
asciilifeform: for photo-heavy / warez etc www, i'd recommend the rk
asciilifeform: also worx
asciilifeform: e.g. hanbot uses
asciilifeform: there is !
asciilifeform: diana_coman presently uses, and BingoBoingo , and a few other folx, worx great
asciilifeform: amberglint: there's an unsold rk ( http://www.loper-os.org/?p=2295 ) machine at pizarro, waiting for somebody's sweet bl0g
asciilifeform: http://btcbase.org/log/2018-01-17#1772041 << see also ☝︎
asciilifeform: mircea_popescu: indeed, tho quite ironically bolix itself was quite analogous to a su research town
asciilifeform: amberglint: let's have it, for completeness, if you can dig up.
asciilifeform: mircea_popescu: recall that these folx had automation that actually worked.
asciilifeform: However, the common way of measuring chip complexity is to count the number of transistor sites; this measures the size of the internal ROMs better. Using that count, this is one of the largest chip ever done, containing nearly 400,000 transistor sites. The chip was designed very quickly (it took about 9 months from the freezing of the architecture to the first prototype chip, using a team of only 4 designers).'
asciilifeform: 'Figure 24 show some statistics about Ivory. The size of the chip was about a centimeter-and-a-half on a side in the earliest version which was done using 2-micron CMOS technology. The first commercial version will be done in a 1.6 micron process and will be about a centimeter on a side, as is the TI chip. This makes it a very large, (but not impossibly large), chip to fabricate. There are about 255,000 actual transistors on the die.
asciilifeform: ble to what you'd see in a 80386 or a 68020 class machine.'
asciilifeform: 'It is of tiie same complexity as an Intel 80386 or a Motorola 68030. Figure 21 is a photomicrograph of the chip (chip people always seem to need to show their chip pictures). The Ivory chip is more or less divided into three horizontal slices; the top is the datapath and stack cache, the middle is the control system, and the bottom is the memory interface. In the middle of the control system is a very large microstore, again compara
asciilifeform: along with buncha else.
asciilifeform: simply means there's 2 metal layer ( conductors ) .
asciilifeform: mircea_popescu: winblowz filenames ftw.
asciilifeform: http://www.loper-os.org/pub/shrobe-1988.pdf << mirrored nao.
asciilifeform: ty
asciilifeform: iirc phf ( and apparently nobody else ) has the actual pinout, but iirc it is on a tape or the like and he hasn't posted yet
asciilifeform: plz
asciilifeform: perma-mirrored at http://www.loper-os.org/pub/amberglint_bolix_1.jpg http://www.loper-os.org/pub/amberglint_bolix_2.jpg , ty ☟︎
asciilifeform: ty amberglint
asciilifeform: and yes photo matches the one given by baker, to the limit of naked eye.
asciilifeform: claims '12.6 x 12.3 mm'
asciilifeform: oh hey the die size
asciilifeform: ( prior to these, masks were drawn 'by hand', on room-sized film, with actual pieces of electrician's tape )
asciilifeform: item was 1 of the 1st ( if not ~the~ first ) machine-layout'd ic's, so it won't be as simple to re as the early 80s cpus
asciilifeform: 390`000 transistor.
asciilifeform: ^ is where i got also only known spec re microcode, '1200 word x 180bit rom'
asciilifeform: may be possible to infer exact metrage from it
asciilifeform: http://www.loper-os.org/pub/bolix-1987-baker.pdf ( warning: pdfturd/scan ) has the only known die shot
asciilifeform: it's approx same item as 386, chemically
asciilifeform: more like 1.
asciilifeform: the die ? i dun think even today there is die whole 4mm tall
asciilifeform: moar typically 5.
asciilifeform: iirc this means up to 9 layers.
asciilifeform: my notes say that it is either '2um cmos' by vlsi co., or '1um cmos' (hp co) if later edition (not known which one we have)
asciilifeform: ( suggests that it's 2cm^2 )
asciilifeform: nor known what exactly size of die, beyond the obv max visible in the photo
asciilifeform: unknown
asciilifeform: loox like top is au-plated iron thermal lid, bottom -- ceramic.
