All,? I have a Compaq Portable ("luggable"), revived from damp storage, and I'm trying to work through some of the troubles it has. First one I'm trying to sort involves the video card. It has the original CGA card in, with the internal output hooked to the internal screen. It has a DB-9 connector for an external C/EGA screen and also NTSC composite output on an RCA plug. I've not been able to test the external 9-pin because I don't have a screen, but I'm going to guess it's working because the internal screen display is good. The composite out is terrible. On several television sets it jumps, losing horizontal sync. The image supposed to be on screen is legible, just. Anyone have experience with this issue (a particular cap, a chip particularly prone to failure) or the schematics for the board? It's tough to trace, being a 3 layer sandwich. If anyone has the schematic for the vdu driver board also, I need to work on that too, it's suffering from dry capacitors. Thanks Phil Andrews Sent from my Samsung Galaxy S?4

Data Translation DT2766 manual?

by brad＠heeltoe.com

Hi, Anyone have a Data Translation DT2766 manual? It's a qbus 4 channel DAC card. I googled everything I could think of and can't find a thing. I could use a pdf (or the real thing, which ever works). I'd be happy to scan a physical copy and return it. thanks! -brad

360-20 core

by BHuntsman＠mail2.cu-portland.edu

Ok, time for a reality/price check folks. What do you all think a whole core assembly, new, for an IBM 360 Model 20 would be worth? Thanks! -Ben

Really old IBM gear

by BHuntsman＠mail2.cu-portland.edu

I see all sorts of stuff for collecting/trading around here, but not a lot of IBM equipment. Anyone do much hobbying of IBM stuff, especially S/360, S/370, and S/390? Anyone know where I could find some interesting artifacts, like a 1052? Or other similar-vintage stuff? Thanks in advance! -Ben

VMS Administration as a modern career (was Re: free VAX 4000 VLC)

by jgessling＠yahoo.com

I was working as a VMS administrator up until 2 years ago.? The healthcare business still has some VMS systems in use today.? The one I took care of ran the GE software for a well known physicians group in San Francisco.? We called it IDX but it had been through many names as GE tried to make it seem modern.? Based on one of the MUMPS variants.? A horrible mess that was susceptible to unexplained problems at any moment.? Very expensive to run since GE charged a lot for support and it needed a lot of it.??? Two years ago, the whole IT departement got outsourced and the overseas staff, India, was supposed to take over.? After a couple months of that I quit in disgust.? I do know one guy still doing VMS at an HMO in Sacramento.? That'll go on for a couple more years.? My Alpha XP900 is sitting unused in my garage.

Data Translation DT2766 manual? (Brad Parker) (cctalk Digest, Vol 122, Issue 31)

Were you after software or hardware info or both? Either way... I don't know the DT2766 itself, but I found a DT2766 picture that looked like 4 simple D2As on a card. Based on that, and on what I remember from a few decades ago, have you looked around for DEC documentation on the AAV11C? There ought to be some in various realtime-related documents which with luck would be available on Bitsavers and elsewhere, but I couldn't quickly find anything useful just now. The AAV11C was a simple PIO dual height Qbus 4channel DAC card (and before it, there was the AAV11A quad height card). If you're lucky you *might* get a pleasant surprise from the AAV11C. Or it might be completely different >from a DT2766, in which case, apologies. My hardcopy of DEC's 1985 Microcomputer Products Handbook has five pages on the AAV11C in chapter 33, covering addressing, configuration, but not connector pinout. Chapter 33 references the LSI11 Analog System Users Guide, an AAV11C Field Maintenance Print Set, and the AAV11 Diagnostic Documentation Kit. Manx says the Analog System Users Guide isn't online, didn't check the others.. There was also an AAV11D which really was a rather different beast, with upmarket features like DMA. Best of luck John Wallace
