Fiddling with the 8088's unused opcodes and the April'86 issue of
PC Tech Journal, I've worked out some of the extra VAX-like opcode
that the NEC V20 can use. These are very useful for manipulating
compressed bit-strings (BCD arithmetic I can do without, not to
mention 8080 emulation in hardward :-). It is tedious to make
large chunks of code around the place for these instructions into
assembler, merely to take advantage of these instructions. Does anyone
know of a better way to make use of these ? Creative suggestions,
no matter how wild, gladly accepted.
