Found it. A very interesting issue. There are several other stories I would
be interested in also. Thank you.

Anyone have any of the docs for this beastie? I have one but no docs. I
have been having trouble figuring out which terminal emulation to use when
connected to it, also If someone has the docs I would be will ing to get my
scanner hooked up again to my computer and see about making a PDF of them
for posterity....

I would like to see it. I have several pieces of core.

The scans are up at http://ti.neurotica.com/core. They're a bunch
of jpegs. No, that wasn't my idea, I didn't do the scanning. :) I
might try to turn them into a pdf one of these days.

I've gotten to the bottom of the "staging area"...I think that pile
of drives is in my storage locker up in Maryland. I will know for
sure soon.

I have some scans of an old BYTE Magazine article (July 1976 I think)
that details how to build a common interface for an arbitrary chunk of
core. I haven't really read it in-depth but I plan to someday. I can
put it online if anyone would like to see it.

I suspect Sridhar doesn't have the S/390s for "historic"
purposes...Ordinarily I'd just shut up and let him say that, but I
just talked with him on the phone, he's outside of Richmond on his way
down here. I'm going to make him eat some beef while he's here. :-)

I believe so, yes.

This is broken. Since 4kbasic and 8kbasic ran on the same altairs it
suggests something in the emulator is broken.
FYI: much of MITS and Altair compatable software used input Port 0FFh
as a 8bit input (usually to configure IO).

I only needed one floppy and with the twisted end cut off
it was perfect.

It's a non trivial thing to do. Core by definition is destructive
read out memory. So to demo a core you need to provide
the coincident current (x,y) and the inhibit/write/read signals
with the associated timing. Both the currents and the
timing are critical. takes a lot of stuff to do that.
