Someone called me to offer 2 19" full height racks. These are in minneapolis, on the loading dock of Riverplace, in Saint Anthony Main. They were asking to see if someone here atthe university would want them, but I rather doubt that anyone does. Especially considering how cold it is right now.. So, if you've been looking for a 19" rack to give as a Xmas present, and you're in the area... -Lawrence LeMay

MicroVAX 3100 update

by xds_sigma7＠hotmail.com

Hi, OK, so the MicroVAX is *still* not responding... I've at least ruled the power supply and the terminal and the terminal cables out however. I put the power supply from the functional VAXstation 3100 in the MicroVAX, hooked up the Wyse 50 I use with the VAXstation along with its DECConnect cable to the MicroVAX (BTW; I used the MicroVAX's manual to set up the VAXstation, therefore the cable must be plugged in properly), and turned the critter on... same results as before.. The console says "_~" and that is about it.. The manual talked about that possibly indicating a disk drive problem, but I tried it both with and without hard disk.. no dice. Any further ideas? Also, I'm going to be finally updating my website with *far* more Interdata/Perkin-Elmer/Concurrent info than anyone could possibly want, along with the same scope of Nova 1210 info, including the sheet on how to modify an ASR-33 with the DGC teletype interface board.

8" drives and Compaticard / Uniform

by edick＠idcomm.com

I can't imagine what's stopping you from reading the diskette, except that I don't believe it helps you to have so many drive types present on the CompatiCard. Having sold mine, I can't reproduce your results. However, it's not a bad idea to read the first two tracks into memory if you can read anything at all, then try to correlate it with a known-good image of the BDOS and CCP. That will tell you about the sector skewing, etc. Some vendors number the sectors sequentially yet read them out of numerical sequence, in order to improve performance. Others write the sector numbers in the optimal arrangement, which is not in sequence from 0. One other gotcha is that some systems require that the first two tracks on the bootable diskette be single density, yet the rest can be double density.

Very Wierd someone is masquarading as the mail list?

by ndiablo＠diablonet.net

Yeah, I dont know what that was, but I got a mail from the same machine only in response to the "Toshiba T3100e/40" question... it included some DOS/Windows executable in attachment.. I'm running UNIX mail, so the whole conflagaration didnt hurt me much, though :) - Sean Caron (root(a)diablonet.net)

VAX 11/780 & LSI-11 console

by ndiablo＠diablonet.net

Well, there's a LSI-11 based PDP system (11/04, i think?) that served as the front-end processor for the system... Nothing really strange about them, besides that PDP sytems are really rather collectible in their own right. - Sean Caron (root(a)diablonet.net)

PDT-11?

by ndiablo＠diablonet.net

I think the PDT-11 was some sort of LSI-11 based "intelligent terminal".. I know someone else out there has one that they did a page on; you can find it at http://www.ultranet.com/~cfriend/museum/machines/pdt-11150.html -Sean Caron (root(a)diablonet.net)

PDT-11?

by dylanb＠sympatico.ca

What is a PDT-11? I just got one new in the box with 7,000+ pounds of other brand new (1965-1978) dec stuff. It has two TU-60s and looks like a VT100. As I am damn near dead and *very* sick... and my family and I had to load the stuff ourselves(last 2 days)... I am not able to list contents yet but .. "TU-56 units a-plenty". I will post pictures soon. I guess I don't have to say a Christmas tree this year is simply out of the question now.....
