asciilifeform: but this tells us ~nothing to narrow it
asciilifeform: fw (or what claims to be the fw, i cannot verify re actual iron) is a c proggy, for what looks like an arm
asciilifeform: so far no dice, not in ru sphere either
asciilifeform: i've been looking for it since it was first mentioned in last wk's thread with the d00d
asciilifeform: google had various crapola fabbed in the past, it wouldn't be a first
asciilifeform: if it's a shelf chip with title sanded off, neither i nor apparently anybody else knows which
asciilifeform: anyway it is asciilifeform's teatime, and so i'ma bbl, inclined folx can puzzle over this puzzler .
asciilifeform: even supposing that cr50 were cleanly removable (the designers would have to be idiots, to make it cleanly removable, really)
asciilifeform: this approach threatens to turn the project into 'phd assembly line', sorta half the point of this machine was that it could be conjured up from the konsoomer shelf version with 10min of effort and 100% yield
asciilifeform: i can heat it to 400C and pull it off the board and see if power still goes ( chances are , it won't, d00d was telling the truth re other boobytraps previously ) , but that's about it.
asciilifeform: the problem is that i cannot answer any useful question about it other than at brainmelting expense ( see the bolix thread ).
asciilifeform: at any rate, if d00d was telling even half the truth re 'we had a cpld, in prev machines, and moved it, among else, to cr50 when we got to make own die' then it prolly is not a standard konsoomer loltron.
asciilifeform: the #1 choice of tardano vendors, certainly
asciilifeform: 2015 box ? 2015 box. does have cr50 ? my probe + naked eye, will say
asciilifeform: should be able to test the truth of the allegation tho.
asciilifeform: which seems to be an almost exactly same machine ( i had it confused with c100 original ) but sans the cr50
asciilifeform: prolly worth examining the c100pa 1st
asciilifeform: or is it for use as hammer ? ( it ain't a very good hammer )
asciilifeform: ugh how do you intend to switch the thing on ?
asciilifeform: mircea_popescu: i'ma definitely lift it, prior to throwing out board, but suspect that d00d was telling the truth re the power button, it doesn't seem to be routed though the old ec controller any moar
asciilifeform: ( and will point out, if i have to cut traces on these, the units will be produces at the rate of one per month, likely )
asciilifeform: whole thread worth reading. presently i have doubt that the project is even worth the candles. ( tldr: there is a nsa rootkit chip on the board )
asciilifeform: possibly even ~two~, there are two roms, 1 is the bootloader, the other is the embedded controller
asciilifeform: and in principle can be used to rewrite the eeprom without fancy solderings...
asciilifeform: the trickiest part of this magic trick still remains to be done, because -- if google's shitpile is to be believed -- one of those /dev/ttyUSBn is actually a spi bridge
asciilifeform: reportedly they use same seekrit plug.
asciilifeform: bonus, should also work , in principle, to control intel.nsa rootkit ( https://archive.li/PCptx derpery & in other 'seekrit whisperings' )
asciilifeform: in other noose, http://btcbase.org/log/2018-06-06#1821018 apparently requires a https://archive.li/9wxqo ( 'partners only' google proprietary dongle ) to enable uart; this, in turn, appears to be a usb-c 'debug accessory mode' magic-voltage set ; and it is deliberately (see below) poorly specced. i dug for the detail, turns out that it is likely being sat on by usg.google et al, because it also enables talking to recent intel iron ro☝︎
