Changing the second byte to 8 gave division by 8, etc.
Argh! I said earlier that the NEC V20 assumed that the value of the
second byte of AAM was always 0x0a. If I'dve checked my notes from
2016, I'd find that I tried this on a NEC V20 and it worked fine with
other values. The "assumed" 0x0a for the V20 is apparently a rumor
that nobody bothered to verify.
My wetware must be leaking, if I can't remember that I checked this one
out 8 years ago.
