Well, first posting, and it's a suggestion, not a problem... Hopefully
that's a good sign, for me anyway.

No, my PC532 isn't up and running yet, though I'm roughly
30% of the way through the soldering. Just waiting on a
few parts to arrive from Steve. Anyway, back to the point...

I've noticed a few people commenting that they don't feel
confident working with SCSI, and would like to have a more
conventional bus to work from. Personally, I'm happy with
the SCSI approach, as it does provide a nice comforting
hardware barrier between the card most of the board. Or at
least it appears to. Shoot me down if I'm wrong.

So, it seems it would be reasonable for someone who has
a) the time, and b) the expertise etc.. (the former seems
to be a rare commodity around here :) to come up with a design
which incorporates some basic circuity to at least ease the
interfacing to SCSI. Perhaps a DP8490 and a bit of DRAM (or
maybe SRAM since, as someone already pointed out, it is
becoming comparatively cheap?) just to get the nasties out
of the way. A description of how do deal with it and what
sort of behaviour to expect would finish it off nicely and
might make some of the ideas that are floating around here
easier to bring to fruition.

Blame me for these ideas. I take full responsibility for them,
but no responsibility for the consequences :-)
