*sobs*  I am _such_ a geek.

If you're after 6502 code, you missed. :)  OTA and INA are not valid
opcodes and even if they were, your addressing is off. :)  The instruction
is one byte and the operands are two bytes, so assuming OTA and INA _were_
valid, you'd have:

1000   INA $1620
1003   OTA $1720
1006   JMP $1000

Which if course would be an endless loop and you'd lock the machine up. :)
