15:07 amberglint asciilifeform: hi, are you still reading this channel? I didn't see any response to my latest message on loggers
15:09 asciilifeform wb amberglint
15:09 asciilifeform yes still reading
15:09 asciilifeform it's a hot spare for the pestnet
15:10 amberglint asciilifeform: apparently someone imaged an Ivory and promises to post pics soon: https://news.ycombinator.com/item?id=36642581
15:11 asciilifeform http://logs.nosuchlabs.com/log/asciilifeform/2023-07-08#1115091 << wasn't me (maybe phf?)
15:11 dulapbot Logged on 2023-07-08 11:28:04 amberglint: asciilifeform: were you the one who gave him an Ivory? https://news.ycombinator.com/item?id=36642581
15:11 asciilifeform i haven't very many to spare , and quite reluctant to give to 'maaaaybe i'll decap without smashing it and maybe sometime will post pics that may nor may not be suitable for reversing' folx
15:12 amberglint I thought so, but there aren't many people with stashes of them :)
15:13 amberglint there were a couple of related auctions recently, with obscene prices
15:13 amberglint one for a MacIvory, another for an XL1201
15:14 amberglint the XL1201 had a faulty console and was missing a mouse
15:14 asciilifeform i have 1 working one in a machine, a pre-release chip, and anuther 2 of the type in the machine
15:14 asciilifeform amberglint: saw the auctions. australia d00d
15:14 amberglint yeah, him
15:14 amberglint I offered the best price I could for a MacIvory but was turned down
15:14 asciilifeform err, 3 spares of the type in the box
15:15 * asciilifeform tried as recently as last yr to work out a deal with a microscopy shop but fell through
15:16 amberglint did you do any work on a testbench with the secret docs provided by phf?
15:16 asciilifeform amberglint: sadly nope, not had time
15:21 asciilifeform as i understand, it may very well take at least 3-4 (if not moar) dies to get a proper image of all layers
15:21 amberglint is it possible to at least extract the microcode ROM from the first die?
15:22 * asciilifeform found out that one can rent time on electron microscope at the uni he lives next to, but they haven't a decapping facility
15:22 asciilifeform amberglint: the rom mask is public (in fact is in the genera cd iirc)
15:22 amberglint oh
15:22 asciilifeform ( see also )
15:22 dulapbot (pest) 2022-11-02 asciilifeform: phf: re microcode btw: there's a 'si:read-rom-word' in genera/distribution/sys/sys/wired.lisp . seems to eat argument n and walk out nth word of the rom. ( not tried it on mine yet )
15:23 asciilifeform ^ can read out the 1 from yer particular unit if you've a working box
15:23 * asciilifeform not knows whether same on all released versions
15:23 amberglint I presume there is zero leaked information on the format of this ROM
15:23 asciilifeform the microcode isn't worth much w/out reversing the die tho
15:26 amberglint I can't remember, do you already have a copy of the paper "The Symbolics Ivory Design and Verification Strategy"?
15:26 asciilifeform not sure
15:27 * asciilifeform suspects that to this day, no 1 person has 1) sufficient bolix dies + 2) the moneys + 3) the time/inclination for proper reversing. not knows how to fix this tho. aint about to send priceless irons to some rando without any obligations
15:30 amberglint asciilifeform: in case if you don't have it, someone scanned it recently: https://www.dropbox.com/scl/fi/gjyrkomdrxx7rx9py3n6f/ivory-design-verification.zip?rlkey=km0i1o7vysxzbzfr4lfeb6e9a&dl=0
15:31 asciilifeform oh hm loox familiar
15:37 * asciilifeform replied to forum thrd fwiw
~ 15 minutes ~
15:53 amberglint have you seen this talk? https://www.youtube.com/watch?v=5uljtqyBLxI seems to be the last attempt to put hardware GC in commercial hw, so far
~ 19 minutes ~
16:12 amberglint I was recently surprised to discover that the Genera 8.3 ISO has some source code that's not in the more widely-distributed leak
16:12 amberglint Symbolics C, Pascal, Fortran iirc
16:13 amberglint some graphics card drivers
16:14 amberglint unfortunately not for the latest(?) one, the Framethrower - this one only has binaries in both distributions
16:21 asciilifeform hmm pretty sure i had 8.3 but not noticed these
16:21 asciilifeform not seen the gc talk (will watch at some pt)
16:23 amberglint "<palter> There was a release, Genera 8.3 I think, where we "accidentally" released all the sources to our customers because we were afraid we were going to go out of business and it would've been lost."
16:24 amberglint_ oops, something happened to my link, sorry
16:25 amberglint_ resending: I tried to diff after reading this message from Gary Palter
16:26 asciilifeform amberglint_: here's the 8.3 isos if you dun have'em
16:27 amberglint_ asciilifeform: yes, this is the exact iso I checked
16:27 * asciilifeform has the Official physical disks, but not checked whether these differ from above
16:27 asciilifeform amberglint_: did the ns src turn up in there too ?
16:27 * asciilifeform not looked
16:27 amberglint_ sadly no
16:27 asciilifeform a
16:27 amberglint_ no NS source, this was my first thing to check
16:28 amberglint_ there wasn't any trace of NS on that iso at all
16:28 asciilifeform evidently not 'all the sources' then, yea
16:32 amberglint_ asciilifeform: it's nice to chat with you, I have to go now, bye!
16:32 asciilifeform thx amberglint_
