Neat design.  The D connector for the serial port is a little
expensive though. ;-)

I've also just downloaded Antti Lukats PIP-02 package, which looks
very nice (I haven't got any 84's at the moment, or I'd have tested
it by now!).  And I didn't think it was possible to write useful
software in Pascal! :->

Only thing is, I want to be able to program '54s as well.  The PIP-02
files refer to a 'ProCheap 1.0' programmer which can do this.  Anybody
know anything about this one?

I'm assuming I'll have to bootstrap via an 84, unless anyone knows
of a 16C54 programmer on about the same budget.  (Perhaps slightly
more: the windowed parts aren't cheap, so I suppose I can afford
a similar amount on the programmer)  I know the ETI design does
these, I was wondering if there are any others?

Incidentally, has there been any progress on solving the infamous
'84 code protect security problem?  Or is it still going to be a
while before that's fixed?

Thanks,

Dave.

(just off to get a 16C84 to play with...)
