I have an isa board with ulnxxx chips on output/input

12 bits out 8 in. Open collector or totem depending on
chip selected. < 1ms switch time.

As delivered handles 50V or 500ma (max power dissapp per 8 bits
are 500mw it's the chip that is the limit)
It includes a 12/24 v DC-DC converter (can be removed).

I have no driver for bsd (although should be fairly straigt forward),
it is used to interface dos software with cincinnatti nc-mills.

It costs me $ to get maunfactered, i pay > 200$ per board :-(

But you *could* use the lp driver and hardware (provided you
modify the driver) and optionally make some external buffering.

Drive Carefully!
