I have once again stomped a bug which somehow refuses to die.
If you are an hardware engineer, please consider including a (maskable)
interrupt for "SCOM input empty". See (or write) me for the minimum
requirments. Now, if you are a game programmer, _please_ do not attempt
to circumvent the carefully designed code in snd_com.asm for "speed" reasons
or because "it's too complicated to understand". It's complicated because
the ^&$&*^%*&^ job is complicated. In particular, trash any and all old
copies of the nefarious "keepcom.c" which keeps popping out of its little
corner of code-hell. Any version which does not include the word "reptilian"
in it is BAD BAD BAD. The version in [68k_us] is ok. If you come to me with
a coin or sound problem, and you are using the old one, I will not only
stop working on your problem right then, but I won't come back until
somebody of director or higher rank tells me to. I know this sounds petty,
but this is at least the third time I've had to deal with this, and posted
a note saying "don't do that", and it apparently never penetrates.

	You might notice I haven't said precisely what is wrong with
the non-reptilian keepcom. That's 'cuz I've said it till I was blue in the
face and wanted to save it for last and in all caps:

	DON'T SEND EXCEPTION COMMANDS TO THE 6502 WITHOUT SAYING SO!
IF YOU DON'T KNOW WHETHER A COMMAND IS AN EXCEPTIONS, DON'T USE IT!

				There, I feel a little better
