An aside to all this... The 1802 was a very strange chip. It was by far
the crudest and yet the easiest to program all at once. My pet peve is
there are holes in the instruction set where a reciprocal instruction
would have been nice but wasn't there. It redeeming feature was it was
CMOS and the only other CMOS part at that time was the 6100 (PDP-8).
What surprized me is that the 1802 (maybe the 05 too?) are still
available. The 05 is desireable as it has the hard coded SCRT
instuction (more like a procedure!).
