Any Mac programmers out there have a copy of GUSI *1*? GUSI 2 is available
easily from sourceforge but it does not like the code I'm trying to link it
to (and I know this code works with 1).

Hi All,
I'm looking for a copy of the old Microport SYSV/AT to run on a Compaq
Portable III I've got. I have all the documentation, but need 5.25"
floppy images.
Anybody have a copy they'd be willing to part with? I'm happy to trade
for other older x86 type UNIX systems. I have several on 3.5" floppy
and CDROM.
Thanks,
Tom
Folks,
I'd appreciate some thoughts in general, and on some specific cases, on using 50Hz DEC equipment on 60Hz power, since I've started processsing and restoring a large quantity of DEC equipment I've brought over from my UK storage to the USA:
1. Thinking about old DEC logic power supplies in general (pdp-8, -11, -12, -15 etc), is there liable to be any problem with using equipment sold in 50Hz countries on US 60Hz supplies? Obviously output voltages would be checked as a matter of course anyway!
Equipment which uses motors is, I would have thought, liable to be more of a problem, for instance:
2. Tapes. Would 9-track (e.g. TU45, TU16 etc.) tapes be likely to be a problem? It occurs to me the transport speed might be a little off...
3. DECtapes (& LINCtapes) : I would imagine they would be less of a problem; they're self-clocking and practically indestructible - you can almost read a DECtape with a toothbrush, some tinfoil, and a set of bicycle pedals! Thoughts?
4. Disks. Biggest problem I would imagine. RK05s I know have different motor pulleys - they're stamped 50Hz or 60Hz. I would imagine running a 50Hz unit on 60Hz wouldn't work, the heads would never load because it would never be detected going at the correct speed. And even if they did load there might be air bearing issues due to incorrect speed. I have around 7 or 8 50Hz RK05s, but only 3 60Hz, so... does anyone have any spare 60Hz RK05 pulleys, or motors with 60Hz pulleys attached? What about RL and RX drives? Similar problems?
Many thanks for any advice
Mike

Yesterday, rooting around my local scrapper I came across several
Analogic AP509 Array Processors which had been rebadged by HP. They
evidently came out of a trashed IC test system which was missing the
computer. Anyone have any information on these beasts or interest
before they hit the parts bin?

You probably forgot the hyphen. old-computers.com works fine, but oldcomputers.com is a squatting page

This core plane appears to be from a Univac Scientific computer,
i.e., the 1103A, made from 1956 to ca. 1960. It's a dead ringer
for a photo in a 1958 brochure on the machine. The 1103A was
an upgrade to the orginal 1103 from 1953, replacing the Williams
tube memory with core among other improvements.

This is one of those things that has bugged me for a while - figured I'd see if anyone else noticed. Many documents on Bitsavers are missing the blank pages.
Now, this isn't much of an issue if you are just reading them on a computer, but they cause havoc when you go to print them out. Call me a tree-killer, but when I'm working on a complicated machine, and find the manual on Bitsavers, I like to print it out, three-hole punch it, and put it in a binder - this way I can work from it, add notes to it, etc, as I restore/repair a device.
With blank pages (i.e. the backs of the last page of a section) missing, when you print double-sided, it throws off the page layout. Sometimes this results in a two-page diagram being printed on the front and back of a single sheet of paper. Or the exploded diagram and the parts list on opposite sides of a page.
So, my solution is to go through the document ahead of time on the computer, page by page, and write down the page ranges that are contiguous, and printing odd numbers of pages together to recreate the blank backs at the end of the section. For example, for the KSR35 Teletype Tech manual, volume 1:
1-3 (single sided), 4-14, 15-26, 27 (reduce), 28-66, 67-113, 114-122, 123-157, 158-164, 165-183, 184-192, 193-217.
Maybe this is just me being a bit obsessive - but I'm sure someone else has run into this. I'm just wondering - were these blank pages removed intentionally for some reason? Did the scanning software automatically ignore them? Or am I the only vintage computer geek out there who owns a massive duplexing laser printer?

Maybe you all know about PhotoFacts but this was new to me. I was spending some time at the library yesterday and noticed a huge wall of (moslty black) binders labelled PhotoFact. I guess they've been there all along but I'd never really looked. They are schematics and service info for electronic products. Mostly radios and TV's it looks like. I got the index from the reference desk and looked up the oldest electronic device I have, an Emerson portable tube radio model 558. Sure enough the schematic and some service information was there. I believe it's from 1947. At the other end of the binders the newest thing I found was from 2006.
I wondered if there were any computer manuals in there. I think there are, I found one for a Compaq portable and some Gateway system, there are also some Zenith data systems items. The binders make it hard to get the pages flat on the copier, but it looks like the pages could be removed and replaced. Anyway $0.60 for copying the four pages was a lot cheaper than the twenty bucks some internet guy wants for that manual, and that one's a copy too.
When I have more time, I'll go back and look further. Regards, Jim
