There are a couple of reference designs on the
internet. Here is one:

Here is another one:

The later provided software too. But the software was
written in assembler language of the xilinx CPU they
made.

I want to see if I can get the parallel port on a
modern PC hooked up to
one of the old SCSI/ST506 bridge boards that I
have,
oh, and if anyone's come across a schematic to do
just that then let me
know where... no point me reinventing the wheel (I
get the impression
that most parallel port SCSI controllers are way
more complex though
because they're built for speed and compliance with
later SCSI standards
- I don't need any of that so hope I can get away
with just a few
latches / tri-state buffers)
cheers
