Weird Lear-Siegler ADM-3A board

by binarydinosaurs＠gmail.com

Hi folks, A friend of mine has said ADM-3A and is baffled by the tiny board it contains, not the usual ?covering entire base? discrete logic board they normally have. Centre of this board is the Nat Semi NS405 ?display processor on a chip? which is obviously why the board is so small but neither of us have seen this before in a 3A. Anyone else?

DEC Mouse replacement

by dj.taylor4＠comcast.net

I would like to have a couple more DEC Mice for some Vaxestations I have, but they seem to be pretty rare.? At present I only have one mouse and I move it from machine to machine. The protocols for the DEC mice and the standard PS/2 mice don't seem to be that much different. Is it possible to use an arduino to translate? PS/2 mouse output and then send it to the vaxstation so that will it mimic a classic DEC mouse?

Modifying microcode

by kylevowen＠gmail.com

Has anyone attempted to reassemble and update the microcode on a MicroVAX? Seems like there's enough stuff here to possibly do it: http://simh.trailing-edge.com/semi/ucode/ I'm thinking about trying to find a microcoded architecture to play with before I design something around the Intel 3000 series. I've got a MicroVAX 3800, so I suppose I could run MICRO2 to assemble the aforementioned microcode. But then what? I assume PALs would have to be burned to implement the new microcode. Or is it more complicated than that? I don't have a PDP-11/60, unfortunately. I do have an 11/45, though...so with this modification, I suppose one could have some fun: http://repository.cmu.edu/cgi/viewcontent.cgi?article=3241&context=compsci Thanks, Kyle

eBay search fail

by jnc＠mercury.lcs.mit.edu

So someone mentioned this to me: https://www.ebay.com/itm/222941705847 Now, the crazy thing is that I religously do a search for "PDP-11" for newly listed items on eBait at least once a day - and this never showed up! I just did a search for sold "PDP-11" items, and it's not showing up there either - although a search for sold "PDP-11 parts" turns it up! Anyone have any idea why it didn't turn up? That is a regular '-', not an mdash or anything, and those are 1's, not lower-case l's. And it does show up in the search for "PDP-11 parts". So I can only conclude that somehow eBait's search function blew out somehow? Anyway, someone got a total steal: at least _3_ H960's, a TU10, and an -11/45 (can't tell if there's an FP11) - and who knows what else is hidden! Noel

VCF East Photo Thread

by silent700＠gmail.com

Many are appearing on the VCFed mailing list already. Here are mine, with separate sets for the non-computer (but still interesting) stuff: http://silent700.blogspot.com/2018/05/vcf-east-2018.html I had a good time and recommend the show to all who can make it out there. -j

TI System V?

by derschjo＠gmail.com

Anyone have any idea where one might track down a copy of TI System V for the S1500 series? I've had these two TI UNIX systems for awhile now, a TI S1505 and a TI S1507 (68030 and 68040-based, respectively). They came without hard drives or OS media and so they've basically been doorstops. I asked around about OS media back when I got them (in 2013) and at the time I got no leads; I'm guessing things probably haven't changed, but I figured I'd ask again just in case... Seem like nice machines, wish I could do something with 'em... - Josh

Restoring a PC Server 500 P/390

by athornton＠gmail.com

I Frankensteined a P/390 together out of a P/325 server and the PCI P/390 card back in the day. I assume you do have the LIC for the P/390 card, without which you?re dead in the water. At least the PCI model wasn?t picky about the disks it used. And I?m pretty sure it?ll work with whatever the final Warp Server release was (4, maybe?) by which time the native TCP/IP support was a lot better. It was a nice little machine for its day, although Hercules is now many times its speed on modern hardware. I used mine to run VM/CMS and Linux (under VM) quite well. Adam

Logic Analyzer software for the HP-IB/RS-232 bus pre-processor HP 10342B

by marc.verdiell＠gmail.com

This has probably been asked before, but does anyone have the software package that came with the HP-IB/RS232 HP10342 bus pre-processor for the HP1650 series Logic Analyzer (actually I have a 1670G)? It should have a config file and an inverse assembler file. I'm interested in the HP-IB files. Can't find it anywhere. - Marc
