I'm still keeping an eye out for a Prophet machine; I only know of one
here in the UK. Not exactly common systems!

Yay! :)

Hmm. No to the copro's. I've not checked the speed though (one copro
went to the museum, I've got a couple - one dead - and I've still got
another one sitting in a pile of bits destined for a collector down
south).

Do you know what differences in parts there were to support 10MHz and
FP? (i.e. were the DRAM speeds different etc.)

I've got a couple of Whitechapel MG-1's at the museum which are pretty
much beyond repair (they'll be spares for an MG-1 I'm expecting near
Christmas). They use the 32016, at 8MHz I *think*, but I'd have to
check. I'm pretty sure they've got floating-point support hardware
(certainly several 32016-series chips, although one's doubtless an MMU).
If it's pretty much a clock change and CPU swap for the higher speed I
might give that a go with one of the copros sometime.

Incidentally, I never have found out why there seem to be issue H and
issue 2 32016 copros out there. There's no obvious difference between
the two expect for the decoupling caps used for the ICs. Why one issue
was based on a number and another a letter, I have no idea. Unless the
CPU speed's different on one vs. the other, I'll have to go back and
look now!

I'd like 'real' copies myself - fat chance of finding any, though.
Scanned versions are well on the way, though! *looks at nobody in
particular*
