    The PSU uses a higher voltage than the battery, so using the PSU on the battery connector will destroy the machine. Using a correct voltage PSU should work, but I never tried it on a Toshiba (I did...

    In most cases, you can just connect the VSYNC and HSYNC lines together. Most TVs should detect that just fine. For more safety, you put two resistors in series before connecting both wires together....

    At least for OS/2 2.1 and Warp 3, it is definitely possible to install on HPFS only. I don't have OS/2 2.0.

    I noticed that Warp 3 formats the partition instantly, while OS/2 2.1 would take forever...

    The 7812 is a linear regulator and will eat the voltage difference itself. So if you drop 18 V to 12 V, at say 2 amps, you will burn 12 W in the regulator, which is a bad idea. Use a switching power...

    Standard troubleshooting:
    - Does it spin up?
    - Does it seek?
    - Check the cables.
    - Check the jumpers.
    - Disable DMA modes in BIOS for the secondary controller.

    It looks like your PSU has two wires, and the internal connector has four (which are pairwise connected together, forming two pairs). Is this correct?

    do 3.5" floppy drives require 12V power?

    I started to build a Z80 based system a few years back, but never finished any disk interface. CP/M runs off a ROM disk for now, which isn't that...
