We confirmed a keynote by Steve Lukasik this morning. Steve was director of
ARPA in the first half of the 1970s when ARPAnet was happening. He also
actually trained at Camp Evans in the 1950s. (Camp Evans was the Army's
name for what is now InfoAge, which is our venue.)
Also trying to get someone from Lucent (Bell Labs), someone from IBM, maybe
someone from Penn (because of ENIAC etc.)

Case anyone here is interested - CNET will be publishing an
artical on the ENIAC on news.com monday morning. I'm told it
will contain 15 minutes of video on the ENIAC and it's creators,
as well as a gallery of historic computers.

Please post the URL after they post that. Otherwise, I will likely forget.
Thanks,

CIS stands for Commercial Instruction Set.
The chip adds new "instruction opcodes" to the processor.
AFAIK it is of little use, unless you have COBOL programs,
or do a lot of string manipulations, and then of course it
is only used if the program recognizes it.
That's about what I know. I have the chip here too, but never
thought of installing it, because it will draw power, generate
some extra heat, and that's about it.
But I keep the chip, it's a bit rare, and because of its looks :-)

Onderwerp: What's CIS for? (was RE: Original 11/74 front panel)
Speaking of CIS, can anyone point me to a good document as to what the
benefits of CIS are? I've often wondered what this is about, as it's a
plug-in chip on my 11/23+

Does anyone on the list have an IBM RS/6000 machine? They had some
pretty spiffy graphics options in the early 90s. I had a coworker who
did some cool fractal demo hacks for them while he worked for the
local IBM office.

Hmmmm...I never thought that I'd see classic computers on modern TV shows or
movies anymore, but in the third-to-last episode of "Arrested Development"
(sitcom) last night on FOX, a Kaypro 10 held the secret to a pivotal
plot element.
There were a whole bunch of classic computers shown including a Commodore
PET.
Yes, I read that 11/74 is in the newest release of E11, and that
you have put in a lot of good work together with John.
But I have never looked into the possibility to connect switches
and lights to work with E11. (I did built the 16 LEDs connected to
the parallel printer port, but that is not a "complete" panel).
In SIMH, I can hack around to connect what I want :-)
E11, from V4, provides hooks, but as said, I did not dive into that.

And e11 V5 actually have the 11/74 implemented, along with the other
stuff needed for multiprocessor PDP-11s. And it works, even if it is a
bit tricky to set up, and not really documented any good.

Yes, I stand corrected. I should have written EIS, Extended Instruction Set.
And as Billy points out, FIS is *not* FP11-x or FPP-x.
I might have taken a bit more time to write it down correct the first time.
OTOH, this is a thread worthy of CC, which is not always the case :-)
have a nice weekend,
- Henk.

Do you mean EIS (M7238) instead of CIS here?

when I said my attempts failed, its due to the way
those disks were stored (i.e theyre just bad). I
probably have ALL the docs for the machine though, a
stack of slipcovered binders 2-3ft tall.

What this sounds like is that he wants something to build up a (say) 128 MB SIMM from 4 32 MB SIMMS, and have it be the same width. This sounds suspiciously like you're trying to build a device to create a composite SIMM, which does require some external logic (often implemented as a PAL). When composite SIMMS were made, they were the cause of some "profanity sculpture", as they tended to not have consistant timing, if I recall. The 8-bit to 32-bit adaptors were/are fairly common, but with 4-16 MB 32/(36)bit SIMMS free to very cheap, not really worth pursuing.
