Altair Replica and Stuff

[TomL_12953]

Well, I swapped the two inverters. The problem stayed where it was, the first port only. So both inverters are good. (You probably already knew that.) Where do I go from here?

TIA

Tom,

You said earlier that you checked the teletype by connecting it to a PC. Does that mean you have a current loop port on your PC?

Yes. I have an Advantech PCI-1603 2-port PCI board where either port can be configured as either RS-232 or 20mA Current Loop (sound familiar?) by setting jumpers on the board. I bought it specifically to run the Teletype with the Altair32 emulator until I could get Grant's replica. It works great!

BTW are there instructions somewhere for using the monitors, DBL, MBL and music ROMS I got with my system? I tried to load 4K BASIC into the replica using your instructions for the TeraTerm terminal emulator but have been unsuccessful. If I could use the MBL ROM to do it, I'd save having to enter the bootloader each time That's the point of the MBL ROM, no? 8^) Thanks again for your patience!
