    Pre-web, I used UUCP also. I may even have some of my old correspondence stashed away there.

    An RPi running Z80 emulation is far more portable--and even boasts USB. :)

    Yup--I remember the bang email addresses. Even before that, there were various private networks. Remember Call/360?

    Check the EPCOS/TDK catalog. There's a 25mm high 220F/400V version. Amazon even has a lot-deal on them.

    WWV-synchronized clocks were available in the consumer market at least starting in the 1980s. The signals are pretty strong throughout the US (and probably a good segment of Canada and Mexico),...

    Isn't that mostly a matter of changing the "home" page setting in "Preferences"? I like blank tabs myself.

    Well, briefly, the Internet didn't exist in the heyday of the 8088... :)

    Now, if you wanted to be period-authentic, you'd rig up a receiver and decoder for the WWV time signal.

    I like to keep a running copy of XP around for reference--it runs on VirtualBox under Linux AMD64. It's serviceable. I have a real XP boot partition as well, just in case, but haven't actually...

    Actually, most of those capacitance values are pretty standard. You may have to go up a bit on the voltage rating (WV = working volts); e.g. 180 F at 450V aren't uncommon at all. Just verify...

    SIMTEL20 is a great source for this kind of vintage stuff.

    I ran across my disk for EA's "Music Construction Set" for the PC, PC XT and PC JR. Copy-protected, of course.

    It would seem to me that the UKans have things a bit easier--portable power tool transformers can be readily had that translate 220V to 55-0-55V, no? Of course, the center-tap ground can also be an...

    Are you certain that the Microbee power supply can't be re-jumpered for 120V? Assuming that there aren't any 50Hz dependent parts in the thing, one approach is to use an isolation transformer. ...

    For what little it's worth, I have a Compaq PSU that looks just like a standard ATX model, but with very different pinout--and the "power on" has to be pulled up to activate.
