    There seems to be some confusion...





    Absolutely wrong! The TI 2532 is NOT the same as others' 2732; the TI 2732 is.

    The barrels from dried-out ball point pens are a good supply of spacer material and they're insulated, so no risk of shorting the PCB to the chassis.

    It has to be a 'real' oldskool fluorescent, not a newfangled compact fluorescent (CFL) bulb, or you could try an LED powered from a low-voltage AC power brick through a resistor.

    Yup, that was my suggestion; forget the resistors & '138, add a couple of jumpers and use 3 x 32K EPROMs; just make sure you put them in the right socket. No issue with the E ROM, just use a 2716...

    Boy, I don't know what you've got there but it sure doesn't match my DIP '138 version of the 6540>27xxx adapter; mine are the same as the SMT version except pins 3 and 1 are swapped and pin 9 is the...

    Go for it; as mentioned it should only involve a few easily reversed mods. You may have to patch the ROM as well if you want to be able to set the 'modem' to higher baud rates.

    There are two ROM types for the M100 but AFAIK the actual contents of the US versions are identical; yes, the 102 and 200 have the pi symbol instead of the inverted exclamation mark.

    Note that (at least) one character in the M100,M10 and KC85 is different from the T102 and T200: CHR$(136), originally a sort-of-stretched tall i, later changed to pi.
