RE: HP97 The journey begins
(11-30-2019 01:22 PM)teenix Wrote: These codes tell the new CPU to jump to a subroutine that processes the messages. This does not exist in the original CPU and I expect the new codes execute similar to a NOP. I will test that in next day or so, but that's what happens in the emulator when these codes are disabled. I added an option to turn the message function on or off so that the CPU can function as a normal 67 if required. Running a program with messaging turned off still works, and as expected does nothing when those codes are executed. The final messages count that can be stored for use ended up being 100. cheers Tony |
