In this vein I thought I'd mention a toy in the latest Jameco flyer I
got. (Don't think it's in the catalog, which is why I'm bothering.)

It's a parallel port (LPT) ISA card which claims to support SPP/BPP/ECP
and EPP, 32 byte fifos (for the more advanced modes), IRQ selectable
from 3,4,5,7,9,10,11,12,15 (lots more than the normal LPT range) and
DMA selectable from 1-3. (LPT ports always had interrupts; modern LPT
ports are bidirectional, some are buffered and/or use DMA as well.)
The kicker is there's a 3-port version of the same card, which is still
quite affordable.

Part number 171651, single port card, $15
Part number 171539, 3 port card, $40
Mention VIP number C67 (the flyer's code number)

It says it uses DB25-F connectors, manual, cable, and CD-ROM w/drivers.

I imagine I have to get a couple, just because.

You might also want a copy of "Parallel Port Complete", Jan Axelson,
ISBN 096508191-5 . I haven't dug into it in depth but from what I
have read it's very very useful.

   Hope this helps,
