Subject: NCR system 3400
We have an old NCR system 3400 here in our office that I would be very
sad to send to the dumpster. Would you be interested?
Unfortunately we are on the east coast.
Thanks,

All this talk of CPUs got me back onto thoughts of homebrew CPU design, which
has been a stalled project of mine for the last year or so.
So, has anyone come across a good online resource which compares vintage CPU
instruction sets? It'd be useful to see what 'core' instructions* were most
common back in the day and use that as a basis for my own homebrew effort; I
think I can probably rustle up things like hardware multiply and divide, but
really don't want an all-singing solution. KISS and all that. :-)
* My hands-on knowledge is pretty much limited to Z80, 6502, 68000 and x86,
and it'd be nice to go a little further back in time - but hopefully without
having to download and digest many different databooks!
cheers

The 1101 256 byte static ram. Later there would be the 2102 (1kx1) and
2102 256x4 that were important to small computeres.
The 1103 was dynamic and while cheaper it was also hard to work with
due to refresh and interface needs.

First, I know approximately nothing about old Intel chips, so forgive
any incoherence.
A friend of mine just came across a couple of Intel 8008 chips.
Apparently, some ebay sellers think they're solid gold.

As far as we can tell, that's what Mel has.
Anyway, I told him I'd try to find out what it's actually worth and
whether anyone here is willing to pay whatever's reasonable.
He also has some later 8008s without the gold cap.

I have, too... I need 4 of them to upgrade my Rejuvenator in my Amiga
1000 from 1M of CHIP RAM to 2M of CHIP RAM (that and a "Fatter Agnus",
but those aren't as difficult to find as the RAM itself).
<http://amiga.resource.cx/manual/Rejuvenator_AgnusInstall.pdf>
It's never been critical, so I've never bothered, but with the Sprit
InBoard and the Starboard on the side (w/StarDrive SCSI interface), it
would be a nice boost.
Worst case, if I ever did start using my A1000 and really, really
wanted it, I suppose I could cobble a daughter card up that would plug
into the RAM bank on the Rejuvenator, but that's a lot of work for a
very optional upgrade.

There are discussions of this in CPU collector forums often. If the price is high enough, it's well worth it (to thieves). China appears to be a significant source for counterfeited chips, mainly "Engineering Samples," "Prototype" and "Confidential" supplementary-marked chips. And I can imagine that somewhere along the line, there were a whole bunch of ICs with exactly the same external appearance as the 4004 that could be remarked. If the buyer doesn't functional check the chip or open it up for die inspection, who'd know other than the thief who sold it?
There is a DEC system module (PDP-1/4/5/6 era) in this lot,
as well as several Control Data modules of the sort used
in the 1604 and 160A. These are nice display pieces, but I'm
well-stocked on both accounts, so I'm going to pass on this
one. With 6 hours to go, the price is at $5 with no bids.
