Many years ago, a company I used to work for did a
Centronics port for TURBOchannel. The timing we wound
up using was data stable 500nS before strobe, strobe
lasts 1mS, data remains stable until 500nS after
strobe. IIRC, this is fairly close to what we found
in Centronics documentation, but I don't remember
what documents we found or what the exact numbers
in that document were.
