All: I?m looking for a copy of the printed manual for Murray Sargent?s Scroll Screen Tracer (SST) debugger program. If someone has it can you scan it for me? I?m also looking for a copy of Windows/286 2.1 disks ? I can?t find mine in my box (crate) of disks. Thanks!

PI 4D/20 (WAS: Re: you *can* get a good deal on ebay)

by compoobah＠valleyimplants.com

Nice beast, a bit slow but decent, especially with the Super Turbo option. In talks with other hobbyists (and experience with my 4D/25 Super Turbo), it seems like the Turbo option is a bit delicate, so you might need to remove the turbo card and plug the RE1/RE2 into the slot (if it is a 1988 model, then Turbo wasn't offered and won't be an issue). The symptoms are graphics lockups. I haven't had time to look at my card and se what's up. It will run "IRIX" 4D1-3.2 through IRIX 5.3 just fine, note that to install from a CD-ROM you need to have a SGI-firmware CD-ROM (there is a hack in the firmware that has the drive identify itself to the SGI PROM as a fixed SCSI disk long enough to trick the PROM into booting >from it), and you'll need to ignore the "install system software" menu option and instead go into the PROM monitor, run "boot -f dksc(0,<CD-ROM device ID>, 8)sash.IP6" and then at the sash prompt type "install". IRIX 4.0 and above deal with CD-ROMs just fine, can't remember about 4D1-3.x. For 5.3 you will want 32MB or more, look on the old "SGI FAQ" for information on the endearing features of the PI 4D/2x memory controller.

Local (NY) PDP guy needed

by rcini＠optonline.net

All: I got an unusual phone call this evening from a doctor on Long Island who is doing theoretical biological research that, he hopes, will have a commercial application. Without going into much detail (because it was like drinking from a fire hose and I can?t remember it all), basically he is looking to emulate some biological processes in software. He believes that the ?instructions? that code for the biological processes are based on 6-bit instructions (or multiples thereof), so he?s looking for someone with that kind of architectural background. A PDP-8 has 12-bit instructions and I think the PDP-9 and 15 used 18-bit words. I?m not knowledgeable about any of the other minicomputer architectures to guess word size, but anything that?s a low multiple of 6-bits should work for his purposes. If anyone?s willing to have a conversation with this person, please contact me off list and I?ll pass on his contact information. Thanks.

It needs a lot more data, but I'd like all listers to feel free to contribute.... Lots of data yet to be entered by me, but the primary stuff is all wikis so you can all add stuff.

wang 2200vp available, Vicksburg, MS, USA

by frustum＠pacbell.net

I was contacted a month or so ago by a gentleman with a wang 2200vp system that he would like to find a home for. I don't need another one, and I offered to "advertise" it here, but then it slipped my mind (it can be quite slippery sometimes). Many years ago in my business I had 2200VP set up complete with a Model 2260 disk drive. I think I had a Wang PC or two also. Since then, the components & the manuals (also floppies & disk cartridges) have been in storage in my attic (well, not the disk drive - whew! -- it is in a corner of my enclosed garage). Do you know anyone that might want any of this? I see nothing on ebay. I'm about ready to haul it all to the dump. Sigh. In a later exchange he said: I'm at Vicksburg, MS, right close to the Mississippi river. Yes, please spread the word that I want to move this Wang system out of my attic (and make room for other junk! ), The $12,000 5 meg (each platter?) disk drive I really think will have to go to the dump. I did not see any mention of it on the web and I doubt that anyone could use it. Have you ever seen the platters offered on ebay? I was thinking of trying that. I'm sure he doesn't want his email address in the archives, so please email me and I'll forward on his email address to you. You can learn more about the wang 2200 from my web site: http://www.wang2200.org

Anyone know the rotation speed of this FDD?

by pludikar＠sympatico.ca

Hi, I have a Sony MP-F52W-30 floppy disk drive, which I need to replace - it semi worked until recently (would read but not write) until I zapped it by accident. It comes from an HP 1650B logic analyzer - does anyone know if it's a 600rpm or a standard 300rpm device? If it's a 600rpm then I've found someone who has one but wants a lot for it, otherwise I'm reasonably sure I can modify the cable connections to use a standard/modern drive. On the motherboard side, it has a Zilog Z0765A FDC, and I've successfully created disks on my PC (using HP's LIFUTIL) that worked on the drive. This makes me think that the drive is a standard 300rpm. Any thoughts? Curiously the serial number label indicates the drive as a MFD-52W-10, while the bigger label on the bottom of the unit shows MP-F52W-30. I guess that the MFD is a base which is then modified to HP's specs (MP-F). BTW Does anyone know what the -10, -30 suffixes mean? I've also seen -00D and -01D around as well. Thanks in advance Peter

Databooks: keep or toss?

by RodSmallwood＠mail.ediconsulting.co.uk

Hi I remember about 1971 collecting a PDP-8 I was going to use to use for control/data capture on a experiment at Harwell. It struck me then why supply such cheap manuals with a multi thousand dollar well built computer system? It was obvious that the books would fall apart if used. I had our repographics people take the books apart, blow them up to A4 and loose leaf bind them. They used research report archive paper (rot proof, fire resistant and good for 100+ years) and as a back up microfiched them as well.

Hi, >>...paper to self-destruct. Think yellowing, crumbling >>paperbacks... > > Umm ... DEC's paperbacks. Actually, my 1979 onwards PDP-11 handbooks are fine. They're printed paper which looks slightly glossy and haven't yet started deteriorating (noticably anyway). OTOH, my early/mid 70's PDP-11 and PDP-8 books are smouldering nicely.... ;-) TTFN - Pete.
