DEC 8MB parity 80 pin SIMMs... what are these from?

by JRichardson＠softwright.co.uk

> I was at the Dayton Computer show last weekend (at the Hara Arena, same place > as the Dayton Hamvention) and picked up a handful of, I thought, 8MB parity > SIMMs. They are, but they happen to be 80-pin, not 72-pin. I've got a feeling my Tektronix XD88 uses 80-pin stuff (they're bigger than 72-pin anyway). Will check this evening if I get a chance. cheers Jules

I will be picking up a PDP-11/70 in a few weeks, but it needs a front panel. If anybody has an extra, please e-mail me. -- Jeffrey S. Sharp jss(a)ou.edu

NeXT '040 Cubes

by pete＠dunnington.u-net.com

On Mar 19, 17:19, MTPro(a)aol.com wrote: > Hi there, I have two cubes, both original 1988 boxes. One is a 25MHz '040 with a hard drive and an optical drive. The other is a 33MHz '040 (Turbo?) with just a hard drive. Both power on fine, do their system test and then say loading from network. The picture looks like a coaxial "T" connector with a cable that has "data" rolling through it. First, put a 50-ohm terminator on that connector, so the NeXT thinks it is connected to a live (but very small!) network. Then read the NeXT FAQ: http://www.peanuts.org/faq-serve/cache/66.html They will not do anything else. I've been going crazy looking on the internet for days, but have not found a way to bypass this. I know you can "boot" into single user mode and then reset passwords, but how? The FAQ describes how to do it. I recently acquired a slab, and had to do that. -- Pete Peter Turnbull Network Manager Dept. of Computer Science University of York

plato terminals

by uban＠ubanproductions.com

Does anyone know where I might still find a Plato terminal of the UIUC 512x512 plasma display variety (not the later CDC implementation)? I know that there were several models, but I don't recall the variations. --tnx --tom

IBM 3380 disk drives / info?

by ip500＠home.com

Among my pickups over the weekend were a pair of these HUGE IBM 3380 drives. Couldn't even begin to find room for the entire unit with its cabinet and controllers, but did scavange the drives and motors out of the cabinet. Biggest drive I've ever seen. Belt driven! from an external 1.5 HP motor ..these things are Big! Cast alluminium housing w/14" discs, the whole assembly seems about 1/2 the size of a V-6 auto eng! IBM site has several references to them, circa early 80's I gather but they sure look older than that. What I'd like to find is IBM publication #GC26-4491 [IBM 3380 Direct Access Storage Intro] and/or IBM pub #GX26-1678 [Storage Reference Summary]. Neither seems to be in the on-line library from IBM. Any other info or dating is always welcome too. Thanks, Craig

You should be able to find the original bookmanager files for those documents somewhere on an IBM web or FTP site. (ftp.redbooks.ibm.com???) There is bookmanager reader software for at least DOS and OS/2 on one of IBM's FTP sites. Having the bookmanager file is much simpler (only one file to download), and can, I assume, be converted to HTML with the same program IBM uses. -- Mark

Cool! It IS a computer. The injectors were pulse width modulated. Somewhere I have the manual for that thing. My mother had a '70 VW type III with that system and it ran great. Joe

IBM 3380 disk drives / info?

by jhellige＠earthlink.net

Were these the 8" 5 and 10meg units? When they required their own special controller prior to switching to SCSI?

I've two of the 10meg boxes, complete with 100 disks, but no controller card. >From what I understand, it was a proprietary interface.
