Epson Portable PC

  • Dear all,


    this is more like a general question - I have recently acquired an Epson Portable PC, to which I would like to connect an external 5.25" drive -


    is there a standard pinmap for DSUB25 external floppy drives, or it varied by manufacturer and device types ?


    If the latter is the case, do any of you know what would be the correct wiring on an Epson PC?


    Thank you in advance,

    nils

  • Since floppy ports (shugart bus) always (should) work with open collector outputs, this shouldn't be learning by destroying:
