who says great deals can't be had on ebay!

by jwest＠classiccmp.org

I was going through the Ebay completed items just out of boredom, and noticed that an HP2748B paper tape reader went for $5.00 back on April 6th. That is one HECK of a deal!!! About a year and a half ago I saw (much to my chagrin, long story) an HP 7900A disc drive in working condition go for about $100 bucks. I missed the 2748B, but wouldn't have bid anyways, I already have two :) Jay West

It's sort of standard DEC for a parallel interface.

Can anyone tell me just how this card maps into the I/O space, >given the CSR? I would like to know just where to read from and write to >in order the drive the beastie... The necessary manuals are all available at: http://www.openvms.compaq.com:8000/ Start with the OpenVMS VAX Device Support Manual ( http://www.openvms.compaq.com:8000/73final/documentation/PDF/OVMS_VAX_SUP_GD .pdf ) and the OpenVMS VAX Device Support Reference Manual ( http://www.openvms.compaq.com:8000/73final/documentation/PDF/OVMS_VAX_SUP_GD .pdf ) Both of these are now in the archived section. The second one of these is basically an introduction to writing a device driver for OpenVMS VAX and includes probably all the info you need for the Qbus mapping in Chapter 14. The Coinnect to Interrupt stuff in Chapter 21 may be a useful introduction if you've not done a full driver before. It will show you how to map the registers and respond to device interrupts. Once you can do that you should have the hang of talking to devices on the Qbus and can move on to doing a driver proper. Antonio

>Does anybody know if motherboard removal was >a common practice in decomissioning tempest computers? Maybe the people that were using it were super paranoid? There is a company near here dumping PCs right now, and each one has to have its motherboard snapped in half before it hits the dumpster.... because they are afraid a rival company will get the PC and find info left behind on the motherboard. (it really just tells me some ignorant person is in charge of the disposal, but either way, it is their policy right now). Hard Drives are being reformatted with one of those secure wiping programs and then opened and smashed. Of course, I can't personally verify this, as the info came to me from a friend, but with some of the moron IT directors I have met, I don't hesistate to believe it. -chris <http://www.mythtech.net>

Some web browsing shows me that Mate-N-Lock pins are still available, but the flat connector shells seem to be gone. On the Compaq web site there are some cables with Mate-N-Lock on one end and various other connectors on the other end, for use with LA30's. I tried to search the Compaq site for Mate-N-Lock but it crashed my Netscape 6, as usual. carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu

While driving home I remembered something that has bothered me about DEC parallel interfaces (DR11, DRV11) for nearly 30 years. Why couldn't they make the programming model the same as the single-channel serial interface? Input control CSR Input data CSR+2 Output control CSR+4 Output data CSR+6 Then you could use the same software driver for an 8-bit parallel device or an 8-bit serial device. Just plug in a different bit of hardware. Actually the Heathkit 16-bit parallel Qbus card was like that. carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu

Can anyone help? There is a program "md5sum" that comes with GNU textutils. It will run on most Unix or Unix-like systems. I suspect that with a fair amount of effort it could be made to run on RT11, compiled with DECUS C, but I haven't really looked at that.. When you run mda5sum on a file it produces a 32-hex-digit "message digest".

I happen to know (from the guy who > runs the place) that the local scrapyard is overrun with these ;) Just remember that all of the NeXT printers are getting on in age, and most of them have one or more of the fatal symptoms: Input roller has dried out so paper doesn't go in. Output gear has stripped so paper doesn't come out. There are other interesting problems that some printers have, such as the "door open" sensing switch insisting that the door is not closed. I don't know how many printers you would have to merge to get one that worked.

CX and SX engines sometimes have problems with crap collecting on the corona wires...especially the transfer corona underneath the paper path. Look for a trough about 0.5" wide with a hair-thin wire running through the middle of it, possibly shielded with a sparse wrapping of a plastic thread that looks like fishing line. Clean this VERY carefully by rubbing an alcohol-saturated cotton swap back and forth over it. That might help a bit. If not, it may be the drum precharge corona wire, which is inside the toner cartridge. There should be a little green plastic tool with a strangely-shaped felt tip stuck into a clip inside the printer. Stick this into the transfer corona wire access slot on the toner cartridge and run it back and forth. It's self-aligning due to the shape of the green plastic tool and grooves in the toner cartridge...there's only one place and direction in which it'll fit correctly. (sorry for the lack of detail here, this is difficult to describe textually) Give that a shot and see how things clean up. If that doesn't help, contact me and I'll see if I can dig up anything else from my dusty memories Canon CX and SX print engine repair training back in 1987. -Dave -- Dave McGuire "Mmmm. Big."
