    Dual Pentium III

    Aren't we forgetting 4+ CPU systems? https://www.ebay.com/itm/200736309992

    Searching for IBM S/23 Datamaster users

    Heckuva setup for an 8085 system. :)

    Tandy 6000 binary-math Basic?

    You learn to write tight assembly code... :)

    Question about retro software.

    Sometimes the beta copies were sent out with time limitations. I never used one long enough to run into that, but I do have a bunch. I'm trying to recall what Release Candidate turned out to be so awful that the next CD that came out was another Beta... I suspect that there's little or no...

    Dual Pentium III

    Such as Saxpy? (whose apparent raison d'etre was to corner the market on the saxpy portion of linpack). "There are lies, damned lies and benchmarks..." I was in that (supercomputer) racket for some time. "Maybe we can make a tweak to the (Fortran) compiler that will be absolutely useless to...

    Dual Pentium III

    Probably the 2007-ish early version. On a dual P3, it mattered some, but not a lot, IIRC.

    Tandy 6000 binary-math Basic?

    In 1979, we ran an 8085 multi-user BASIC with standard BCD 14 digit + 1 byte precision. I wrote the code, recoded in in 1980 to be suitable for M80 assembly; it was also used in a couple of Sorcim products--and I still have the source. Don't recall what the CBASIC precision was, but I think...

    Dual Pentium III

    I do know that early on, there was a dual CPU version of gzip. Don't recall the name now.

    Dual Pentium III

    For years, I ran a SuperMicro P6 dual slot I P3 board with SL4BS CPUs. Ran DOS, 98, 2K and XP and Debian Woody on it. Storage was a 250GB SATA SSD with a PATA-SATA adapter. Still have the board; the lack of SSE2 sort of limits your options.

    Weak Disk Imaging

    Disk magnetics are pretty stiff; the majority of problems I have are with shedding or contaminated media. IMD is pretty good, but I guess you can't boot MSDOS?

    How do I test this weird conner hard drive?

    Darn--I got to you too late. See: https://stason.org/TULARC/pc/hard-drives-hdd/conner/CP-30084E-85MB-3-5-SL-IDE-AT.html Under "J4". I suspect that you have the +12 and +5 swapped. Likely the drive was toast anyway. Out of my several Conner <500MB drives, none has survived.

    IBM 5154001 Monitor: Needs recapping

    A very likely candidate is the RIFA safety capacitors used to control line noise on the AC mains. Very common; doesn't damage the unit.

    Can someone tell me what this external Tandy HDD goes to? I honestly dont remember.

    The number of pins and labeling on the connectors leads me to believe that a standard ST412-type controller will work just fine.
