These "names" aren't going to prove as helpful as the model numbers. I have a 7585B which is, I believe, the precursor of the Draftmaster series, the principal difference being the presence of a drive for the chart feed and some different body panels. It's not at all certain that the behavior you've described characterizes any malfunction at all. The fact that HP people suggest it's broken doesn't mean much either, by the way. HP has a habit of disposing of people once they've learned enough about anything to be really useful, and their salesmen never get to that point. I do have the manuals for the 758x series, by the way.

Piece of classic FORTRAN code

Richard Erlacher wrote:: << Golly! That does bring back the memories . . . but wasn't the CDC6xxx family 64 bits? I cut my teeth on that one, back in the mid 1960's and it seems that it (the 6600) was a dual-processor version of the 64-bit 6400. The CDC 6400, 6600, 7600 all were 60 bit, definitely. The Cray-1 is the first 64-bit machine in the Seymour Cray line. Those were the days . . . FORTRAN-II, SCOPE OS, COMPASS assembler . . . batch processing . . . (that meant you wrote your code on a 24-line 80-column "coding sheet" and, when finished, gave them to a woman behind a door with a small window in it . . . and got your error listing a few days later) . . . I'd have given a week's pay for an hour in that room behind the door . . . mini-skirts . . . (you do remember keypunch operators and Hollerith cards, don't you?) Dick >> It does bring back memories !

Help with LS-DOS 6.3.1 was ( Need a copy of TRSDOS 6 OS)

A long time ago, I wrote a small ASM program for formatting disks and creating bootable images under DOS but, I don't really want to do that right now. I do have a Linux box here so, options 1 & 2 sound the most appealing. I'll hang a 1.2MB floppy on it and grab Tim's app (since it's already in a FTP directory). It could be a week or two before I get around to it. I'll let you know if I have any more problems. Thanks Again, Steve Robertson - <steverob(a)hotoffice.com>

no rom basic

by edick＠idcomm.com

An important thing to keep in mind, however, is that not all drives adhere to the latest, or even the more recent standard. Since this discussions centers around old hardware, I'd be REALLY careful with ide interfaced devices. Case in point: I once used a number of MAXTOR MXT540A drives, which were WONDERFUL . . . they were fast, (6300 rpm at a time when most were 3600 rpm) beyond belief at the time and very reliable. After a couple of years, Hitachi came out with a nice CDROM drive, the 7730 (?) of which I bought a number. Unfortunately, when I placed the HITACHI CDROM as a slave on the same cable with the MAXTOR HDD as master, the servo on the HDD was overwritten, which I only was able to verify after destroying (irreparably, because the hardware with which to rewrite the servo didn't exist at MAXTOR any more even though the drives were still within their two-year warranty) half a dozen such hard disks. The CDROM certainly claimed to adhere to existing convention, as did the HDD. MAXTOR was not able to explain the malfunction, nor were they able to replace the drives with anything comparable. --pity-- Dick ---------- > From: Eric Smith <eric(a)brouhaha.com> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: no rom basic > Date: Monday, February 08, 1999 10:58 PM > > jpero(a)cgocable.net wrote: > > You done exactly right on everything except LLF which is big NO > > No on modern drives, potientially losing it! > > I wish just for once that someone would actually cite a specific drive > model for which this is true.

Mini clearout

by kevan＠heydon.org

Hi, After having moved to our new house I am gradually filling the garage with stuff I have had in storage while the move happened. As part of this process I am finding things I didn't even know that I had and things that I don't have space for any more. Below is a list of things that I would like to pass on to other collectors. * Box of about 100 8" DEC floppy disks * A number of old DC300 and TK50 tapes. * Olivetti Logos 250 electromechanical calculator * A hand cranked mechanical Olivetti calculator * Communications Machinery Corp Multibus II Ethernet Node Processor ENP-70 * Prime EXL CPU board - I believe this goes with the above ethernet board. * Digital engineering Inc. VT640 Retro Graphics board. I am located in Cambridge UK. I don't really want anything for these items but offers of something to trade would be looked on favourably. -- Kevan Collector of old computers: http://www.heydon.org/kevan/collection/

Unix for 8080/Z80? [Re: WooHoo!! PC/XT Unix anyone?]

Many people have added VM support to applications running on non-MMU hardware with little loss of performance. The Amiga has a few of these, most notably Personal Paint by Cloanto.

Amiga Crisis, (was MEI/Microcenter is out of 5-1/4" diskettes)

Well, >they're also in a bit of a crisis thanks to the idiots running Amiga, Inc. >killing the market last spring when it will be quite a while before the new >Amiga is ready to ship. You're right about the disk crisis. Amiga magazines are falling over themselves to get a decent supply of DD disks. As for Amiga Inc killing the market, quite probably but from what I have heard the new OS is closer to release than everyone thinks (whatever that means) and as soon as I have enough money I'll buy a Viper PPC with a G3 processor.

Intergraph Clipper hardware

by kevan＠heydon.org

Hi, I would like to get a Clipper CPU based workstation but know very little about what models were made. Does anybody have any information on what machines Intergraph made. I do know that some models were huge dual display + tablet systems. I don't have the room for these but if they did smaller deskside or even desktop systems then these would be of interest. Many Thanks -- Kevan Collector of old computers: http://www.heydon.org/kevan/collection/
