Fwd: Looking for an HP16702A or B logic analyser mainframe

by alexandre.tabajara＠gmail.com

Dear friends, I'm trying to find a nice and stuffed 16702A or B to buy, shipped to Brazil or NV, USA. B preffered but I can use the A. I'd rather have it already stuffed (a pair of LA cards, oscilloscope and who know, pattern generator) Anyone willing to part with one? I can do paypal Thanks, Alexandre

ABLE, other non DEC boards.

by useddec＠gmail.com

I had a nice talk with an old friend earlier today, and we talked about how some companies were so proud of their products that they never put their name on it. Sometimes a logo, sometimes only a part number. Bitsaver is great- I don't don't know what any of us would do without it. But There are a lot of items that, at least I, can't turn up there or on Google. While looking for the ABLE (ACT) board that Mattis was talking about (and I found it for a list member who has first dibs on it) I came across: Computer Consoles 343d01533 Computer interface Tech -looks like a DZ11 clone CMD CDU-700/T witch I think can be upgraded to a M/T SCSI Unibus Simpact Assoc inc ICP-1600 DPD might have been bought out by CDA Computer design and Applicationd.which might be a subsidiary of Analogic. MM3000, 40199 2mg, FPPC Some of these I've heard of, some not. I have a few hundred DEC compatibles, and I'm tired of going through them. Duel, quad, hex, and 780. A lot of Emulex, dilog, ADAC, Data Translations. Please contact me off list if you are interested in any. Pics would be nice. Thanks, Paul

RK05 spindle pulleys - trade 50Hz vs 60Hz?

And long after WWII! In the 1960s, I had a Motorola 140D (140 for the power, "D" standing for Dynamoter) mobile radio (6 meter ham band) in my car. Everytime I keyed the mike, the dynamoter would instantly spin up with a loud whine. Such radios were normally housed in the trunk of the car and required heavy wire to carry the 12 volt battery current for the dynamoter. My Monarch 10EE lathe originally came with a big motor-generator to power the variable-speed DC motor. Later versions use thyratrons, while even later ones were solid state, but they all continued to use DC motors. The variable-speed DC drive was very similar (identical?) to elevator drives, known as the Ward-Leonard system. To bring this back to the RK05, someone asked if anyone had a copy of the RK05 IPB. If you still need it, let me know and I'll dig it out. I haven't packed it for my move yet, but the drives are. Alan

Note that ConnectorPeople has a relatively large minimum order. Quest has the male connectors (i.e. female pins), but not the females. Noel

HP-2116 front panel lamps

When I was "doing sort of " C.E. for 2116 ( 1971 _ 1981 ), we were using CM 380 as replacement. Even longer life !!

But it would be nice to be corrected here. According to one dealer Web-site, what I think are those connector shells are now out of production. However, as I indicated, I have located several places that still have some, and I have ordered some to verify that they are the right thing. If they are (they should be here at the end of the week), I will send another message with part numbers, sources, etc. Noel
