Looking for keyboard for a BLIT / Teletype / AT&T terminal

by ian.finder＠gmail.com

Hi Folks, I need help hunting down an item. This is a keyboard that shipped with a few AT&T / Teletype terminals with a 6-pin RJ connector. I recently obtained a BLIT terminal and would like to find a keyboard (and mouse- the red lady bug one- if possible- but the keyboard is quite necessary) Also any advice on how to deal with screen rot would be appreciated. Thanks, - Ian

STSC APL*PLUS System for VAX VMS User's & Reference Manual

by mark＠wickensonline.co.uk

For those who expressed an interest in the STSC APL*PLUS manuals for VAX/VMS I happy to report they are now available from here: http://wickensonline.co.uk/static/files/scans/APL-Plus-System-for-the-VAX-V… http://wickensonline.co.uk/static/files/scans/APL-Plus-System-for-the-VAX-V… Apparently the free PC version is very similar to the VAX/VMS version so these manuals should be of direct use. You can run the PC version of APL*PLUS within DOSBox and it is available here: http://www.math.uwaterloo.ca/apl_archives/apl/apl-plus/ Regards, Mark.

MC68451 datasheet wanted

by spacewar＠gmail.com

Looking for an MC68451 datasheet (or scan). Most of the ones that turn up from the usual database sites are actually for the MC68450 DMA controller, which is entirely unrelated. The only one I found that is actually for the MC68451 was "Advance Information" from a databook, and did not include the pin grid (R or RC suffix) pinout. There was a "loose" (not in databook) datasheet that is more recent, labeled "Preliminary" rather than "Advance Information", and later versions of that include the pin grid pinout. Does anyone have that?

docs & sw wanted for Heurikon HK 68/ME-2 and HK 68/M10-3, Micro Memory Inc. MM-9000

by spacewar＠gmail.com

I've got one each of the Heurikon HK 68/ME-2 and HK 68/M10-3 multibus boards. There are brochures on bitsavers, but does anyone have documentation, schematics, or software for either of these? It also would be nice to get documentation, or at least switch and jumper settings, for the Micro Memory Inc. MM-9000 Multibus/iLBX RAM board. I have the 4MB version, using 144 256K DRAMs (includes parity), but there was apparently also a 1MB version using 64K DRAMs. Aside >from the DRAMs I expect the difference is in the jumper or switch settings.

PDP8/e front panels A and B

by rodsmallwood52＠btinternet.com

Hi Guys! I now have prototype artwork for the two types of 8/e front panel. They differ only in the switch markings. They do both have the same extra (but cosmetic only) features over the first run. Regards Rod

PDP-12 at the RICM

by michael.99.thompson＠gmail.com

The RICM Learning Lab was nice and cool today so we spent the afternoon chasing the "LGP GP=GPC PRESET" in the TC12 LINCtape controller. With a logic analyzer connected to lots of the TC12 signals were were able to chase down the signal that is causing the fault. We are now not sure if the signal behavior we observed is the correct behavior, and there is a fault elsewhere. More debugging time and more studying of the documentation is required. -- Michael Thompson

Wang Model 370

by earl＠baugh.org

Howdy, Went on a rescue last night and while there were three machines I knew of (a PDP-11 that I'll give more details on later, haven't looked at boards, etc, since it was part of a Particle Measuring System, an HP 85-ish machine and a slightly later HP machine) there was one thing that I hadn't known about... (aside from the very cool old GE 'scope that the guy is keeping... ) A Wang Model 370 Calculating System with a Model 372 Data Storage System. Gotta say this is the oldest thing I've picked up (1967 it came out). No idea if it powers up or not... Definitely needs a cleaning (basement, fairly dusty unit) but before I did anything, was wondering if there are any experts out there that have worked on one of these before who'd be willing to share any helpful hints on verifying this is working... Thanks... EarltheSquirrel
