Ok, this is what I was looking for. Any ideas on pricing? I hope TI still 
makes the thing. Does anyone know of any other chips that will provide 
similar stuff? While we're at it, perhaps you could let me (us) know why 
you do favour a 34010 solution? I personally would go for the dumb 
framebuffer if it were possible to do it cheaply enough...

Hmmm... My feelings here are that if we're going to put a parallel port and 
an FDC on the motherboard, it should only be done at the expense of the ISA 
(or other) I/O bus. A card with a parallel port and other junk costs 
virtually nothing. Putting a "real" parallel port (ie: bidirectional) on 
the motherboard would be a waste of board space and effort (IMHO).
