    Assembling VG version 4 monitor

    Hi Mike,

    Progressing slowly, but progressing never the less.
    I'm pretty sure I have worked out the serial port assignments, at least for the console port.

    I want to re-assemble the VG monitor...

  6. IBM Xebec 62X0776 MFM controller card, ROM wanted

    Hi all,

    I have an IBM Xebec 62X0776 MFM controller card missing the IBM ROM.

    25294

    A few questions:

    What size is the ROM?
    Could I replace it with the equivalent sized EPROM?
  7. Can anyone identify these cards for an IBM PC/XT

    Hi All,

    Ive been given an 5160 XT with a few additional (Taiwanese clone boards).

    I've mostly cleaned and restored the 5160, but would like to identify these boards if possible.

    I know their...

    Hi Mike,

    I moved the start address of the FDC to C800h (as a test) and I can see the ROM, so that strongly suggests the RASE80 is also decoding the F800h address range (the board has NO jumpers...

    Hi Mike,

    My mistake, it is missing.

    I found the ROM it was at BC00h, switch 5 seemed to make no difference.

    Sounds too good to be true, shouldn't be an issue, is there a source code listing of the ROM anywhere.



    Definately a Z80A, dual serial ports, software programmable baud rates.

    Rebirth of an S100 System

    Hi Mike,

    Yes, I agree, my apologies to those who originally asked about 10 sector hard sectored diskettes.
    I have started a new thread, entitled "Rebirth of an S100 System".
