Yet another Mystery board

Well, this one may not be a mystery if I am right, but I may not be.
Microtek 'SLOTWARE'
4 SN74xxxxx chips and a socketed chip with a label over it
has a 26-pin connector directly on the card, like the old disk ][
contollers were. I'm thinking it may be a parallel interface, since I
think I may have gotten some huge daisy-wheel printer with it at the time
and I think that this would have been the only way it could have been
attached, but, unfortunately, since there is no adapter to go between the
card and the back of the computer, I guess I am SOL.
