Intel 4004

by edick＠idcomm.com

Actually, I'm not that excitable about making old hardware work. I am interested when someone does some of the things I did with parts with which I didn't. I didn't get interested in microprocessors until the 8008, which, by the way, though still functional when I unplugged it from the circuit board, became a "high-tech tie-tack" which I wore from time to time along with others of about the same ilk and vintage. With all the fascination over the internet and GUI OS's, etc, it's easy to forget that the old 8080 can still process the words and generate the payroll as well as it did 20 years ago. Printers are faster too, I guess, but since the essential demise of multi-part paper, it takes about as long to generate the 4-part documents as ever. Some things will just always be painful . . . <sigh> I find it interesting to note, however, that you've taken the pain to do this work yourself. Rest assured, it can't be any worse than the tools everyone who worked with this primitive beastie had to use.

Accidental deletion

by kyrrin＠bluefeathertech.com

I think I might have accidentally nuked some responses to my latest manual offering. So far, I've received one offer from Hans Franke. Was anyone else interested in a Motorola 68000 'ExorMacs' System Manual? Three inches thick and 9+ pounds, vintage about 1980. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com Amateur Radio:(WD6EOS) E-mail: kyrrin(a)bluefeathertech.com SysOp: The Dragon's Cave (Fido 1:343/272, 253-639-9905) "Our science can only describe an object, event, or living thing in our own human terms.

HP plotters

by edick＠idcomm.com

You'll need to find someone local with a pickup truck, since you probably won't find anyone willing to pay what it costs to ship it. I paid $385 to ship mine from Pennsylvania to Denver. The "Draftmaster" 7596, I believe, that we had at work weighed considerably more than mine, though it didn't plot faster, or, in any detectable way, differently. It cost and weighed more, and was more massive in its appearance. It was, however, an excellent device. one more thing . . . imbedded below.

I sent the manuals (user guide not included) a Programming Manual and a Technical manual, the latter of which has numerous 11"x33" foldout drawings, and they have sat at the printer's for a couple of months waiting for an estimate on reproducing them to be finalized. It won't be cheap because of those foldouts, which are half-tones. > > So, if anybody wants them... > > Nasos. >

Piece of classic FORTRAN code

by edick＠idcomm.com

Yes . . . that's how I remember it, too. Those irritating core dumps were always recongnizable as they went through the line printer, since they sounded like a chef chopping celery. I never did get to where I could actually gain anything from a core dump. I guess it hasn't changed much, though the dumps Windows95 gives you when a process goes askew aren't as long.

Piece of classic FORTRAN code

by edick＠idcomm.com

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. 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?)
