I'm not lazy, just impatient and afraid to burn something down. I've
been unable to get my distributor to sell me a copy of the Site
Preparation Guide, I understand that the answer is in there. I'm too
remote to be able to borrow one, but I need to hook up a printer to pp0
on the hpsio-8.
The connector is a DB-25S, does anyone know if the pinout is the same
as a pee cee? I have cables that will work on a pee cee parallel port.
I suppose I should just try it, but it would be my luck that something
would be grounded that shouldn't be. My distributor's sales prevention
outfit is so good that they can't even give me a price (I gave them
the NCR part number) for a "real" one.
Sorry for the dumb question, but conventional efforts thus far have been
futile.

I have cables that will work on a pee cee parallel port. I asked the same question several months ago, and somebody else asked almost the same question at about the same time. (Gee, maybe we should start a FAQ list, I'll even volunteer to maintain it and post it regularly.) The answer is ..... (opening the envelope) ...... NO, the pinouts are very different. I have them around here somewhere ..... (rummaging through old NCR postings, loud clanking noises heard, rather like Fibber McGee opening the closet door) .....Ah, here it is. Gee, did I really ask this question way back in February? ..... >In article <80@texbell.swbt.com> writes: >> We've just installed a 650 with 1 HPSIO card.
