I agree, but you'd better start re-designing the monitor since it has a
*few* single source obsolete parts that make *me* nervous! They're
definitely more likely to die.

All good reasons, but I think Al's original point was ease of design, which
is directly related to completion time.

You can start this evening wiring up some banked EPROMs on an existing
speech board and have it done by the time you go to bed (there's something
to be said for that) ...and not to be too cynical, but I'll wait for the
"all in one" DSP card's availability before I worry about freeing up a slot.
