> anyone willing to chip in some money to help me pay for this? I sent a chunk too. This is a totally great acquisition: I have a KDJ11-B board that has a bad bus driver chip; I was going to apply an ohmmeter to find the guilty party, but just looking at the prints will be so much easier. I see it also includes MSV11-R prints, which is wonderful, since we don't have prints for those either. Too bad it doesn't include the MSV11-J prints (also missing), since the -R's are rare and the -J's are relatively common. Noel

Bitsavers has saved my bacon multiple times and it's only right that I support you. In about a month I hope to be able to deliver the 7-track tape drive to you. Details later. Alan Frisbie

DEC ADV11-D Analog to Digital converter with DMA

by mark＠matlockfamily.com

Paul, Jerry, Thanks for the suggestion to take a look at DataTranslation! Looking in the bitsavers folder for DataTranslation, I found a 239 page July 1986 Data Translation manual for the DT3362 series of A/Ds. There are 23 sub-models of that board but the DT3362-16SE/8DI specifications matches the ADV11-D (A1008). The best part is that chapter 8 of this manual has 5 programming examples, two of which use the DMA capability.With a bit of research (and some luck) I think this will give me the info I need. Thanks again, Mark Date: Sat, 17 Oct 2020 02:06:25 -0500 From: Paul Anderson <useddec at gmail.com> I think they were made by Data Translation.

Toaster Flyer - proprietary drives?

by jules.richardson99＠gmail.com

I've been talking to the guy in NYC who has the storage portion of what appears to have been part of a Toaster Flyer setup (I forget who, but someone on the list forwarded details a few months ago) - two 5.25" full-height SCSI drives, a 3.5" SCSI drive, passive ISA backplane, and some form of TBC card (made by DPS). I'm not sure who made the 3.5" drive, but the two FH ones appear to be 9GB Seagate Elites (I'm assuming they were the two video stores, and the 3.5" was for audio). The big question is whether in a Flyer environment the drives run custom microcode or will have been LLFed to something other than a "standard" 512 byte block size - I believe that the Flyer was really pushing the boundaries of what was possible when it was current, and the majority of drives on the market just didn't have the necessary throughput (I see a "Newtek approved" sticker on one of the Seagates). I know that the storage was considered "proprietary", but I don't know if that just means that the filesystem was Flyer-specific (i.e. not AFFS), or if there was more to it than that. cheers Jules

S-100 stuff, electronic stuff, model railroad stuff, books and magazines!

by mechanic_2＠charter.net

Hello all. I have 22 S-100 boards for sale. There are two backplanes. One is a 9 slot bare board and the other is a 19 slot fully populated board. Both boards have active termination. There are 8080, Z80, FDC, HDC, Serial, 68030, a Display board, a Front Panel board. There are also 3 Mean Well power supplies supplying the +9VDC and the +_16VDC. There are also voltmeters and amp meters . I want $500 plus shipping for all of it. I can provide a full inventory and pictures for anyone who is truly interested. I probably have cancer and if I do I am dying. I want all of this to go to a good home and not to the landfill. If anyone is interested I have some test equipment, electronic components, and model railroad equipment Please only serious inquires for I tire very easily. GOD Bless and Thanks, rich!

Configuring an MS11-L for an 11/24

by cz＠alembic.crystel.com

So I'm working on this old MS11-L board I have had sitting around forever. M7891 DK. Goal is to use it in my 11/24 with KT24 MMU. I've switched the jumpers so it will run on a +12 supply instead of a +15, and so it will run in an extended Unibus slot as opposed to a normal unibus. However I'm stumped regarding the +5v and +5 BBU supply lines. The problem is the manual says to set the jumper that is above C12 (bottom of board, two capacitors next to each other, pretty easy to spot) so that W3 is in and W7 is out if you just have +5v. On this board, W3 is out, W7 is in, but there are two other jumpers right above them (nothing is labelled on the board). So.... Is it the bottom jumper that is +5 or the bottom and the one above that need to be moved? This might be why this board never worked right, if the memory refresh is expecting power on the BBU line and I don't have that then it's not going to work very much :-) But which jumper is the right one to use? Thanks! Chris
