Got a few goodies today at thrifts and the warehouse

by jrkeys＠concentric.net

While going through the warehouse today a came across a 59 page document titled OSI Challenger SYSTEM PROSPECTUS. It sold for $1 and looks like it was printed before May of 1977. It has allot of technical information in it. At a local thrift picked up a Commodore Minuteman MM3S calculator with square root key for 99 cents. Good shape (looks) but not tested yet. At another place got a Monteverdi TV Sports 825 model E825A with one controller for it. They had two controllers there for $2.99 each but one was broken into pieces, so I left it. Also there was no power supply or instructions with it. Also at the warehouse I picked up a TI2500 in the box that I had there and a Laser 50 PC that was billed as a educational computer and had 6 modes you could work in. It's missing the battery cover on the back.

MicroVAX II

by Antonio.Carlini＠riverstonenet.com

>I've since pulled all the boards, installed a M7625-AA (KA655) and M7621 >(MS650) 8MB memory card by themselves, and got a chevron prompt. I also got a memory error and a >message stating normal startup is not possible. 'show memory' showed 0MB of ram installed. I tried >another 8MB board with the same results. I also tried 3 different 16MB boards, but the LED display >showed 'F', and of course, I didn't get a chevron prompt. You know that the over-the-top connector used on the KA630 and the KA65x are different? I don't know exactly what failure you see if you use the KA630 OTP with the KA65x - but you may just have found out! It seems odd that a PSU could cause this problem and I'd be surprised if *all* your memory boards are faulty (I've never found a dead one even after they'd spent quite a while floating round the lab).

scored OS/2 2.1!

Looking for a DEC VT420 maintenance print set.

by healyzh＠aracnet.com

> Ops, I meant to say that I am looking for a vt420 print set, not vt440 (if > that even exists). > > --tnx > --tom As far as I know, there isn't such a beast as a VT440 (to bad, it would probably have been a very nice terminal). As for finding any kind of a print set, good luck, the VT420's are new enough that DEC didn't seem to release much in the way of doc's. Zane

Tektronix DC100 tapes?

by glenslick＠hotmail.com

Did any Tektronix equipment use tapes that are compatible with HP DC100 tapes? I found a couple of unused tapes that have a Tektronix label but no part number that I can see. They look pretty much the same as an HP DC100 tape. I suppose I could just try them in an HP 2645A I picked up after I clean up the tape units, but it would be nice to know whether or not they really should work first. Also, anyone use HP 9144 tape drives, or have one they are not using? I found a couple of unused tapes for those units. _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.

Zilog System 8000 guts in Oregon

by Innfogra＠aol.com

Going through my storage locker I ran across the card cage with cards and some connecting cables from a Z8000 system. I am interested in selling this. So I am offering it to the list first before it goes to ePay. If anyone is interested please contact me for information or offers at innfosale(a)aol.com About 10 cards in the cardcage with backplane. I can't get to it to identify them at the moment. Zilog 1982 copyright on the backplane. The original looked a lot like the 8000 system 31 in Australia about 8 years ago. This was salvaged from my scrapper partner at the time and has been in storage since. It is now in Astoria, Oregon 97103, USA. I can quote shipping prices. Paxton

8 bit vs other Computers.

by Robert_Feldman＠jdedwards.com

I did a lot of productive work on an Osborne I, with a 52-character wide display, but it was a bit of a PITA. Personally, I like a display that can show 60 characters, as that corresponds to a typewritten line with the margins I use. On an 80-column display, I get too much wasted space on the right. 64-columns is a good width, and is what I use on my HP 200LX palmtop (which can display 80x25, 64x18 and 40x16). OTOH, the 104-character wide mode on the Osborne (with an external monitor, of course) was useful for SuperCalc spreadsheets. -----Original Message----- From: Stan Barr [mailto:stanb@dial.pipex.com] Sent: Monday, November 25, 2002 3:25 AM To: cctalk(a)classiccmp.org Subject: Re: 8 bit vs other Computers.

Zilog System 8000 Model 31 available in Australia

I've never ran out of code space in my 15 year ( when I was doing embedded stuff ). Then I could never understand what happened to all the space that most of today's compilers use. I've always used a combination of assembly and Forth for embedded stuff. I had to work with a few applications written by others that were in C and found it very difficult to stay within RAM limits for even simple applications. When I first saw languages like SmalTalk, looking at the description, I thought that finally someone was doing something right. They talked about the efficiency of reuse and such ( concepts that are natural to Forth ). Then I tried it and found that it was more bloated than the C programs I was dealing with. The other thing that bothers me is that today we have computers that can run several thousands of times faster than an 8080 IMSAI. Still, it takes 5 to 10 minutes to boot that machine. My IMSAI boots faster than I can reach >from the reset button to the keyboard. I'm told that is is because the machine has to figure out what the I/O looks like on each boot ( of course, MS rejected OpenBoot for PCI boards that could have improved the boot time ). I find that applications written for these new and more powerful computers that have been doubling in capabilities every year are becoming garbaged up at a rate that is faster than the computer get better. I doubt there is anyone that works for MS that even knows if 50% of the software that they release is even being usefully run under any condition ( maybe even 80% ). I believe that there complexity will eventually bring them to the point that even hiring the entire graduating class of computer science students will not fix. Just my ramblings Dwight
