I've been on this list for about 2 years, but I have to say that
sometimes I miss some of the posts because I can't cope with the
traffic.
To answer the last part first, yes the P850 was
perfectly operational
last time I used it (about a year ago), and I don't see any reason why it
should have failed since then.
OK, to the programmer it looks like a 16 bit machine, but it's actually
got an 8 bit ALU and 8 bit data path to memory. Every word is processed
in 2 cycles, one of the low byte, one for the high byte.
[very interesting description of the machine deleted]

Thanks Tony! looks like a rather interesting machine to learn
about processing units. I don't have any machine with a TTL-implemented
processor. I'll keep my eyes open for one...
