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,


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