What did you ask "Santa" for this year.... : )

by csmith＠amdocs.com

> -----Original Message----- > From: Loboyko Steve [mailto:sloboyko@yahoo.com] > Where can I get one of these. Not the SGI Indy... I'm not sure, actually, I think it was a limited edition or possibly a prototype that they -- for some stupid reason -- never allowed to reach production. In fact, if you take "classic computer" as a descriptive term for a person who uses "classic computers," maybe she should go on the "hardest to find classic computers" thread. ;) Regards, Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

Pyramid 90x

by dancohoe＠oxford.net

I recently brought home a Pyramid 90x. The old owner who had run the machine at his work in the 80's bought it from his employer about 1990, but never got it set up at home. Apparently he decided to dump it a few months ago, but because of its size didn't get the job done. However, he did put all of the software and the documentation on the curb for the garbagemen at that time. Mike Kenzie and I got there just before he called the recyclers for the machine itself. What I need is a boot disk or other software and any documentation that might be out there. According to the old owner, it starts by loading the boot program off the 8" floppy before it can find the fixed disks. Does anyone have anything for this machine? thanks, Dan Cohoe

I am kind of leaning towards that option. The only question is price. My guess is it should certainly be less than $200 or so to have done, and likely less than $100, depending on the work involved.

I've taken a look at the card-cage, actually. From your description of VGX graphics, it seems to me (not having the thing in front of me right now) that I may have had too many boards. What are the chances the graphics have been upgraded without changing the tags?

6502/Z80 speed comparison (was MITS 2SIO serial chip?)

by CLeyson＠aol.com

Come on guys cool it. Who really cares if a Z80 is faster than a 6502 ? I sure as hell don't. For those who are interested check out the following: US Patent 4004281 Microprocessor Chip Register Bus Structure (6800) US Patent 4332008 Microprocessor Aparatus and Method (Z80) US Patent 3991307 ...on the fly correction to provide decimal results (6502) By the way, the 6800 Patent has complete circuit diagram. The Z80 also contained DRAM refresh circuitry that the 6502 didn't.

Now I'm impressed.

The SYSTEM password was "system". > TeeHee. I've had SYSTEM, "MANAGER" before. :) You can boot them conversationally, of course, even if you don't have the password, and gain privilege. I've done this on a good three or four machines, and there are a couple different ways to manage it.

Round two: PC vs the Dishwasher

by rschaefe＠gcfn.org

Well, it turns out the case isn't in as good of shape as the boards inside it. After a good washing, the cover has surface rust all over it. Not from the washing, but from the 'storage' it sufferred thru before I came across it. I ended up taking out the top drawer to make enough room to stand the case on it's end. I tried with it sitting flat on the top of it, but that didn't work out so well-- hadda run it thru twice. Bob

8284a, where to find?

by ajp166＠bellatlantic.net

From: Robert Schaefer <rschaefe(a)gcfn.org> >look for another one-- mouser and digikey are all that comes to mind. (Is >this an 8284a, or an 8284?) The 8284 and the 8284A are not the same part and it will make a difference. The 84A is easy to fins and common to many clone wrecks. Allison
