I don't know that much about them but think they are descended from the HP 2100 and 21MX processors used in earlier 1000s (and would like to find out more, so corrections are invited). What are the first four digits of the serial number? That will give you some idea of its age; first two digits are probably year less 1960, next two digits are week-of-year. > It says "hp 7970E" It is a 1600 BPI 9-track drive.

Pop the lever in the center of the supply hub up, and slide your tape on. Leave the lever up for now; you will be pulling tape off the supply reel and if the hub were engaged you would have to turn it too. Pull the tape off the supply reel, threading it around the stationary post, then the tension arm, then the heads (lift the cover over the read/write head to thread the tape through), then the other tension arm, then the other stationary post, then onto the takeup reel. Hold the tape against the takeup reel -- stick your finger through the little hole -- and make a turn or two of the takeup reel to get the tape firmly held on the reel. Push the lever on the supply hub down to engage the supply reel. Now you can push LOAD to get the tape drive to scan for the load point. If it just keeps going and going then there is a problem with the light/sensor assembly. ONLINE puts the drive on-line. Won't work unless the tape is loaded. RESET is "stop what you're doing and take the drive offline". REWIND is "rewind to load point or 'til the tension arms lose tension because the tape came loose from the takeup reel". 0, 1, 2, 3, OFF switch the drive's unit number; OFF is effectively offline. Note that unit number may not have an obvious relation to the system's device name or number. I don't know much about RTE (the OS on the 1000s) but under MPE on classic 3000s it was a component of either the DRT number or the unit number, which were in turn referenced by the logical device number. > Any info is appreciated. Hope this helps, if you have more questions feel free to ask. -Frank McConnell

Old arcade game?

by kaikal＠MICROSOFT.com

If you jumped buses, it was Atari Stunt Cycle (1976). Basically a clone of Atari Night Driver (http://www.pipeline.com/~jhardie/gallery/coinop/nightdrv.jpg), which I believe owns the title as the original "black & white dots" driving game. I don't recall what Atari's earlier entry (the first driving game) called Gran Trak looked like. Another well-known example was 280ZZZAP.

Pertec cabling

by kyrrin2＠wizards.net

I can't speak for the 7970, but I can tell you that Pertec formatted connections are usually a pair of 50-pin (25 to each side) PC edge paddles. I've seen a few (very few!) devices, specifically an old Unibus tape controller, where one connection was a Berg 50-pin header and the other was an edge paddle. From your description, it sounds as though the drive may not have its own formatter built in, outside of the HPIB interface section. I could, however, be mistaken (read: I'd need to see the drive). -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin2(a)wizards.net) http://www.wizards.net/technoid "Our science can only describe an object, event, or living thing in our own human terms.

DEC DOC LESS

by dcoward＠pressstart.com

I dug these boards out of a closet last night to find enough boards to get an H-11 up and running. I was wondering if any of the DEC experts out there could identify the purpose for any of these boards.(Names come from whats written on each board) They all appear to be Q bus. M7940 or M7946 RXV11 LSI 11 Interface (Half width) I may have written down the wrong board number here. This, I'm 90% sure is the serial interface board I'll need to connect a terminal to the system. At least it looks like one I had on my LSI-11 many moons ago. If it is, I sure could use the pin-out for the connector and baud rate settings. M8340 Decoder and Step Counter (Full width) M8341 Multiplexers and Timing Generator (Full width) These two boards are linked togather with a connector across the top of the boards. M8639 RDRX Disk Controller (Full width) Is this a hard drive or floppy controller and if its a floppy controller, is it single or double density? M7957 Asyn Mux (Full width) M4002 ? (Half width) M8189 KDF 11-B (Full width) This appears to be a processor board with only 3 of the 5 sockets filled. M8043 ? (Half width) I have the processor board covered. I have about half a dozen M7264 LSI-11 processor boards. But, I could also use a list of commands for the resident monitor. Damn, I can't even remember what it's called.

Harris flyback transformers for H192 terminals:FS

by dseagrav＠bsdserver.tek-star.net

My boss is getting rid of a bunch of these. New and used. $35 apiece new, the used ones are $10. He's trying to clean out the back room. Can anyone use these? We have around 50 new, and 500 used ones.
