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.) ----------------------------------------- Evan Koblentz's personal homepage: http://www.snarc.net Computer Collector Newsletter: >> http://news.computercollector.com Mid-Atlantic Retro Computing Hobbyists & Museum: >> http://www.marchclub.org >> http://groups.yahoo.com/group/midatlanticretro/

CNET artical on ENIAC

by dave04a＠dunfield.com

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. -- dave04a (at) Dave Dunfield dunfield (dot) Firmware development services & tools: www.dunfield.com com Collector of vintage computing equipment: http://www.parse.com/~ddunfield/museum/index.html

What's CIS for? (was RE: Original 11/74 front panel)

by henk.gooijen＠oce.com

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 :-) - Henk, PA8PDP. ________________________________ Van: cctalk-bounces at classiccmp.org namens Julian Wolfe Verzonden: vr 10-02-2006 19:09 Aan: 'General Discussion: On-Topic and Off-Topic Posts' Onderwerp: What's CIS for?

IBM RS/6000

by legalize＠xmission.com

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. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

OT: Kaypro 10 on TV sitcom last night (Feb 2006)

by dzubint＠vcn.bc.ca

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.

What's CIS for? (was RE: Original 11/74 front panel)

by henk.gooijen＠oce.com

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. - Henk. ________________________________ Van: cctalk-bounces at classiccmp.org namens Johnny Billquist Verzonden: za 11-02-2006 00:52 Aan: cctalk at classiccmp.org Onderwerp: Re: What's CIS for? (was RE: Original 11/74 front panel) 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.

What's CIS for? (was RE: Original 11/74 front panel)

by henk.gooijen＠oce.com

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. ________________________________ Van: cctalk-bounces at classiccmp.org namens Tom Uban Verzonden: vr 10-02-2006 20:58 Aan: General Discussion: On-Topic and Off-Topic Posts Onderwerp: RE: What's CIS for?

archiving hard drives, Televideo PM/4T and AT&T7300

by chrism3667＠yahoo.com

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. --- cctech-bounces at classiccmp.org <doc at mdrconsult.com> wrote: > Chris M wrote: > > I have 2 systems in particular for which I'd like to > > create images of the hard drives (well it would be > > nice anyway).

SIMMS and other memory dongles

by compoobah＠valleyimplants.com

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.
