    I still have an NEC MultiSync FP950 19-inch flat screen CRT monitor, which is the last CRT monitor I bought. That must have been at least 15 years ago, and probably cost a few hundred dollars at the...

    Look at the datasheet. There is a brightness control resistor connected between VDD Pin 6 and and the brightness control input Pin 7. A lower resistor value should allow more current to flow into...

    I had a couple of those several years back. Neat systems. I somewhat wish I had kept one of them, although I never actually did much with them when I had them.

    A common problem with those is the...

    Not sure exactly what you meant by Future Domain being a "precursor" to Adaptec.

    They were competitors with their own SCSI controller product lines in the 1980s, until Adaptec acquired Future...

    The original poster should have bought that DYS50D for less than $90 shipping as soon as it was noticed instead of giving other people a chance to find it and snatch it up. Even if the chassis was...

    If you want the option of running 2.11BSD you need a J-11 CPU (at least in the Q-Bus world).

    The current cost different between a J-11 CPU board vs. an LSI-11 or F-11 CPU board isn't that...

    Did this other person use an S-handle version of the M7554 with the S-handle frame still attached in a DYS50 chassis? I have doubts about the mechanical compatibility of the S-handle frame with that...

    An STMicroelectronics M2764A-2F1 is a fairly common EPROM. I would be surprised by a decent device programmer which doesn't have a programming algorithm for that specific device.

    Someone just bought this lot of 25 T&B 609-25P parts for $17. I suppose that might be an ok deal if you needed several of them and needed to be that exact style.
