    Or the guy who runs his car on water using magic pills?

    I can see the 5170 being used a multi-user system; after all, we had Z80 boxes being used in that way also. We ran a (gasp) 8085 in 5-user...

    I have a digicam set up as a sort of copy stand. Every once in awhile, it seems to think that I'm lying on my side. I run the result through gimp, but it is annoying. There's probably a setting...

    Er, every PS/2 had EPP (bidirectional) capabilities, which dates from 1987.

    Could well be--I don't know much about that particular model.

    Deskpro M--is that the 486 CPU on a card EISA model? It may simply be too old to support ECP/EPP.

    Some SPP implementations still observe bit 5 in the control register as switching off the data drivers. Have you tried that?

    I tried the fan with a 5VDC supply--spins right up, pushing a lot of air, drawing about 600 ma. and fairly quiet. I may use it that way. Much lower than that (e.g. 3VDC), the fan squeals, but...

    I've been using the F407 evaluation boards for years. Cheap (at about USD$9) with all the bells and whistles that one could reasonably want for most things:

    Certification of computer equipment for use in nuclear power plants is an arduous, slow and costly process. I recall a friend who worked for GE in the 1980s saying that they still used core-memory...

    The nice thing about RL compression is that you can compute checksums on the uncompressed data and the compressed data at the same time you're looping through the data doing compression-at least in...

    I've been through the specialists and nobody around here practices brachytherapy any more. Apparently, there was a group who made a hash of it locally and nobody wants to touch it. So the only...

    I wonder if that's the same book that I gave away last year. I also gave away a complete copy of IEEE 1284 at the same time.

    Compression depends on the nature of the data that you're...

    At my age, the "few years more" matters less than the quality of those few years. My own mother lived to 90, but I wouldn't want to live her last 5 years for anything. Barely aware of her...

    As I said, somewhere around here I've got a little Chinese 24V fan control board and thermistor probe. I don't even remember why I picked it up.
    I'm pretty sure that it will deal 12V well.

    Heck,...

    A good friend passed away a few years ago. He was a Korean war vet, probably about 150+ pounds overweight, got no exercise and what he ate would give me cardiac failure. For breakfast, 4 eggs,...

    I think bugs were present only on the initial 16032/32016 chips, which were very late (I started talking about them to the NS guys in 1979).

    I think that the later chips, as used in laser...

    It was not uncommon practice at the time to use CPU loops for timing delays. The D765 controller in the CC I/II definitely requires delays between certain operations. Fast hardware renders these...

    For whatever it's worth, calling the interrupt a "Divide by zero" is a bit of a misnomer at times. What's really happening is that the DBZ interrupt vector is at 0000:0000, so the interrupt can...

    Are you using the CC I drivers?

    If not, have you tried reading/writing disks of both densities?

    I've owned both CCI and CC II boards, but never used them as primaries.

    Motherboard fan ratings?

    I've got a case that can accept a 120mm fan. I also have a 12V 120mm fan that is spec-ed at 2.5A. Is it safe for me to plug this into my motherboard's case fan connector, or should I use an...
