Help on odd diskette

by cclist＠sydex.com

I've got a rather ancient 8" diskette (hard-sectored; 32 sectors) with the Harris Lanier brand on it. About all that I know is that it was created during the 1970's and contains word processing documents. It looks to be MFM with the usual n, 1.5n and 2n frequency distribution, but I'm not getting much meaningful from digesting the bitstream. Does anyone have any clues? Cheers, Chuck

by Billy.Pettit＠wdc.com

Andrew Hastings of the controlfreaks list has put some old computer industry ads up on the web: http://www.dvq.com/oldcomp/oldads.htm They are chronological, so pick your favorite year and enjoy. Excellent job - I was filled with memories. Billy

Plextor officially no longer manufactures SCSI drives

by fireflyst＠earthlink.net

Maybe I'm behind the curve on this, but here's something that may be important to those of you with SCSI hardware; Plextor was praised by many as the best/most compatible CD/DVD (esp. scsi)drives money can buy. -----Original Message----- From: Sales Main [mailto:sales at plextor.com] Sent: Tuesday, July 25, 2006 12:13 PM To: Julian Wolfe Subject: RE: SCSI DVD-R/RW?

MLP-900

by aek＠bitsavers.org

> I was thinking software simulator... still a challenge? Yes, just due to the complexity. Much of the low level stuff would have to be reverse engineered for the later machines, since that is what software survives, but it is not documented as well as the earlier stuff. I also suspect the only language that survived is COBOL, though there was FORTRAN and BASIC (a C was written as an experiment in Santa Barbara and LISP at the U of Utah, but there is no sign that they survived). Burroughs used the concept of "S-Machines" (interpreted instruction sets in microcode) on several of their low and mid range systems. Same idea a P-code. Docs exist for the instruction sets for some of their high level languages (there was no assembly lang for the system). The cold-load on all but the very last of the systems were from cassette. I have them, but need to read their contents.

by pspan＠amerytel.net

Hi Chris, Do you have the prom images that need to be programed? If so I know I can program the national series. i do not htink that I have any blanks in stock at the moment, but I am located in Amery WI. If you can send the images as a binary or hex file, they should be able to be programed. Phil

> How about the B-1700? I used one once and it was really interesting. > Has anyone archived any old tapes or software for those machines? Any > known emulators? The situation on that series is a little better than most of the Burroughs machines. CHM has a not-quite last generation machine (19xx) as does William Donzelli. Some software came with the CHM machine, I went to one of the last guys who took care of them in TN a few years ago and brought back a large stash of maint docs/sw and a card set from a 19xx he had in storage. Since there are a lot of B-1xxx alums in the Bay Area, there is some possiblity the CHM machine could be restored. A hardware simulation of the machine would be a challenge. Unfortunately, there were lots of interesting software/langs for the machine, and almost nothing has survived that I've been able to find. Same is true for the B5xxx/B6xxx etc. series. Univac and Burroughs had a scorched earth policy and almost nothing survives today from their old machines.
