More Info (was Re: HP 2100S microcode blanks?)

So it thus appears the same chip (or compatibles after programming) can be
used for all of the following:

HP 2100S microcode
HP 21MX-M/E/F loader roms
HP 21MX-M/E/F 1K microcode (but not 4K or 8K microcode chips of course)

Even finding 82S129's at 5 bucks a pop, still makes it painful for me to buy
about 40 of them *sigh* I wonder if it's possible to move six 1K 82S129's
into an 8K chip (I think 82S181) without the processor knowing it. Might
make those Access IOP microcode chips more cost-effective.
