EXDOS card (compact version)

Brief information

It is a clone card EXDOS. Compact version designed by pear. It includes the Bus Bridge on-board.

Jumper J9 near a power socket:

  • Short: card and a EP powered with a common power supply connected to the card,
  • Open: card and a computer powered with separate power supplies.
Do not connect the interface to the computer when the power is on !
The original Enterprises power supply does not have enough power to both the computer and the card !

If you want to use a single, common AC adapter should provide 9V voltage and current of about 3 - 4A. In the case of the power supply connected direct to the card's polarity can be any (the card has a diode bridge).
