Right... The 2051 has about as many outputs as a 16C54 PIC around 13 or 14
I think. Those get eaten up fairly quick with 8-bit databus type outputs,
but since you don't need all the parallel functions (Midway, G-80, etc) at
the same time you can just do one, or trigger some external latches if you
want to...

Oh, that's cool. I always used DPTR to index into data memory so I never
had to look for the alternative. ;-)

Still kinda spendy. I bet a 16C54 would do the job just fine. I just
don't like those funky PIC lookup/jump tables.
