Absolutely, and this shouldn't be compromised. I do think that a lot of
the common peripherals can, and probably should, be handled by the
FPGA. If nothing else, it saves you slot space for the interesting
things. This was the IIgs's most attractive feature for mine, that you
got all the 'standard' stuff without adding a card, leaving 7 slots for
more advanced things. I think it would be worthwhile to extend the
"design" (dare I call it that) to include that feature.


I  like the idea of an extension to the system to virtualise 5.25"
hardware, allowing the permanent archival of all my 5.25" media and
drives.

Depending on the depth of virtualization, that could be either
a tall order (quarter-track spirals) or a snap (CFFA card).


That's certainly true, but the design leaves scope for somebody to do
that over time...


Yes, I regularly assemble a few thousand lines with Merlin 8 Pro, and
with the screen listing turned off, it does it in seconds, not minutes
(with an 8MHz Zip Chip).  That's fast enough that I don't get out of my
chair.  ;-)


Yeah, although I sit there, with my eyes smarting a little bit from the
fatigue of a 60Hz, slightly blurry 20 year old display, wondering when
the day will come that some critical (at least, to my needs) component
will decide to open a blue-smoke vent.

Ah.  I guess I'm old enough that I can imagine that my blue smoke
will escape before it escapes from something I can't fix (I *do* have
spares).  ;-)

Come to think of it, that may be why *everything* looks like its in
60Hz and slightly blurry...   ;-)

Actually, Matt, I suspect that we are in fundamental agreement about
what we want and why we want it.  The only thing we may not be fully
aligned on is what we think will happen to satisfy our needs.
