Altair 8800b + drive alignment

by jfoust＠threedee.com

Acrobat PDF versions of the Shugart SA800/801 Diskette Storage Drive Maintenance Manual can be found online at: <http://www.tardis.ed.ac.uk/~itda/frames.html> This is the page of the Internet Techincal Documentation Archive, a project with the admirable aim of securing official permissions to scan and post the documentation of archaic computer equipment. They have some Terak documents online, but not much else. If you can think of other documents that might be able to be posted in this fashion, please drop them a note! They'll do the work. You'll have to send the scans or paper to Edinburgh, though. - John Jefferson Computer Museum <http://www.threedee.com/jcm>

Change that URL... (pdp8a CPU picture)

by DSEAGRAV＠toad.xkl.com

You will have to append a / to that... (So it becomes http://209.174.127.164/pdp8/ ) Sorry... -------

Ehehe... I've scanned my KK8-A board! Pictures online!

by DSEAGRAV＠toad.xkl.com

I mean, a paper is flat, and a board is (mostly) flat too, so why wouldn't I be able to scan it? Answer is, I can. It works fine. The only bug is the board is bigger than the scanner... I'll be retryin throughout the day, you can see the pictures at http://209.174.127.164/pdp8 Tell me what you think! Oh, and I wouldn't try this with anything with EPROMs on it... :) -------

Stuff, while we're at it...

by manney＠nwohio.com

Thanks. I'm in Ohio, 44857 As I understand it, you have a complete system, with a (fuzzy?) monitor? Is there a HDD, or is that the bernoulli? Is there software?

EPROM programming voltages

by yakowenk＠cs.unc.edu

Can anyone point me to an on-line reference showing the necessary voltages for programming various EPROMs? I'm especially interested in the oldies-but-goodies: 2708, 2716, 2732, and 2764's. In particular, it seems some of them want 25v while others want only 21v, and I suspect that even the same chip number from different manufacturers may want different voltages. Thanks, Bill.

Video connectors (was: CGA Modes (Wuz: Win 3.0))

This exact combination, when used for parallel printers or external >SCSI, is almost indestructible. One problem with that is that the average centronics connector is wider (thicker?) than the standard PC slot allows for. I believe this may be true of Mac slots as well. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

ALERT: Free tri-density tape drive needs rescue!

This is a tri-density upright unit with formatted Pertec interface. It worked the last time I used it, but, as I look at it now, it appears that the backup battery on the CPU board has failed. It would likely be necessary to run through the calibration procedure after replacing the battery. (I recall doing the calibration before, so it must be in the manual. These drives have an RS232 port to control the diagnostics.) I also have an extra drive (with mechanical problems) for spare parts; they should probably go together.
