- I recently picked up the following stuff at a university surplus sale. I
- don't really want it, but I hate to see what might be decent computer
- equipment go to the landfill. What's this stuff worth, to you, if you
- want it, or if not, how should I get it to someone who can use it?
-
- (Note, I've included price information for stuff where I could, mostly
- from my Federated Consultant's Summer Sale price list -- That's also the
- list I used to map from DEC's module numbers to useful descriptions of the
- boards. This price information is really meaningless, because I don't know
- that any of this stuff works.)
-
- 1) A Q-bus backplane (H9275A, 9 slot quad), in rack mount enclosure with
- power supplies, fan, and front panel with reset and power switches.
- Made by Data Translation, model DT4253-Dr, SN 5051
-
- This is really a nice package; the fans and power supplies alone are
- probably worth $40.
-
- 2) A Q-bus backplane (DDV-11B, 9 slot hex).
-
- 3) M7270 (KD11-H) LSI-11 (PDP-11/02) CPU.
- Retail price $125
-
- 4) M8186 (KDF11-A) PDP-11/23 CPU (missing an option chip, the MMU?).
- Retail price $225
-
- 5) M8044 BB Memory.
- Retail price $65
-
- 6) M8028 (DLV11-F) EIA or Current Loop serial board.
- Retail price $85
-
- 7) M8043 (DLV11-J) 4 channel EIA serial board.
- Retail price $125
-
- 8) M8016 function unknown, but might have something to do with power.
-
- 9) Texas Instruments TMM10010-01 Q-bus mem. board, ASSY 1700150-02, SN 0705.
-
- 10) Data Translation EP057 Rev J, SN 72421-317;
- function unknown, but has 40 pin berg connector, 10Mhz crystal.
-
- 11) Data Translation EP125 MCP Rev D, P/N 02181, SN 68452-306, quad height.
- Has DT5712 analog mux and analog to digital converter module.
- Has DC-DC converter, +5 to +/-12.
-
- 12) Data Translation EP075 Rev F, SN 73682-301.
- Has DT212 12-bit digital to analog converter module.
- Has DC-DC converter, +5 to +/-12.
-
- 13) Data Translation EP058 Rev F, SN 76622-329.
-
- 14) LSI 50 Alloy Eng CPD, SN 5115, quad height. Function unknown.
- Has 40 pin Berg connector.
-
- 15) Scientific Micro Systems Prog Assy 1001939-0001, Assy No 0003770-0001,
- SN LE8056, function unknown, but could be ROM.
- Has 40 pin Berg connector.
- Has 20 MHZ crystal.
-
- All of the boards had been pulled from their original slots in the
- backplanes by the time I got to the pile, although I think that all
- of the Data Translation cards and most of the others came from the
- Data Translation box (item 1).
-
- I'd appreciate any advice I can get (by E-mail) about finding a home for
- this stuff. If you know of places that buy old DEC stuff on the gamble
- that some of it might work, or if you know of PDP-11 hobbyists who might
- want the stuff as spare parts, please tell me.
-
- At the worst, the stuff is good for parts, but I'd guess that much of it
- is still functional.
