Sorry for the repost... but has anyone heard of
the (old) Dataproducts printer inteface?
It was also called the Line printer interface, and
was used on other Brands besides just Dataproducts.
Basically I know it uses differential signals - otherwise similar
to centronics - but I would like to find out some details.
I have the Pinout:
http://www.hardwarebook.net/connector/parallel/dataproductsdsub50.html
I would really like to find a description of the
"Demand" signal and the polarity of "Strobe" and "OnLine"
I would like to know the levels (I presume they are TTL)
If anyone can help me out, perhaps I can respond
in kind by giving them the final result - a circuit
for a Centronics-->Dataproducts interface.

FWIW:
I've never heard of a "Dataproducts interface" but I've seen dozens
of
Dataproducts S-100 cards including printer interfaces. They do, or at
least did, show up regularly in the scrap places around here (Florida).
Usually there are some name brand S-100 cards with them. I pick up the
standard brand S-100 cards but not the Dataproducts ones since I have no
docs for them. I've never seen the machines that the cards come out of so I
have no idea about them.
