Hey All,
Taking my time bringing up my Altair system. It has a REV 0 8080 CPU board, I had to replace a cap on the 32K RAM card and now I can examine memory and deposit into zero page RAM. I have a National Multiplex 2SIO card and I've checked the manual and the 2nd serial port is wired for RS232. I've verified the transmit, receive, ground RTS-CTS DTR-DSR are connected correctly. I'm trying to understand this card more and I see there is a built in monitor, but how do I configure baud, stop bits etc? Also, the manual says C000 but the ROM is labeled F000 and data is in F000 not C000. I just want to examine some memory at this point, I'm ready to connect but a little stumped at the baud rate settings.
