I also have some questions of actual users of the Altair. I wanted
to use a copy of Palo Alto Tiny BASIC on the emulator (because that's the
BASIC that I have), but TB relies on CP/M for console I/O. Regarding the
original Altair BASIC, did the BASIC code provide its own I/O services or
did it use CP/M also? What port locations were generally used to service
serial ports used for console I/O? Does anyone have a working set of CP/M
binaries that I can load into the emulator?
Hi
There was no standard port used for serial I/O. and even if
there was, the device could have been a AY-3-1015, a 8251 or
a 8250. All of these would have different handshake and
setup information. I don't know how you'd be able to have
anything that you'd call standard.
