Hello all
I like the idea of basic serial I/O. A lot can be done with a decent VT100 emulation on a PC. You could also have an add-on card position(something like the Arduino uses?)- for video, or keyboard perhaps. Maybe just use the bare necessary pins to communicate and not all 100 of them for the add-add on location? This could save one or more card edge connectors- not to mention all the soldering! Your idea sounds good to me; I think it would be fun to play with.

The only part I'm not sure of is what to do about console output/video. Was thinking of using the basic Propeller Console IO circuit http://s100computers.com/My%20System%20Pages/Console%20IO%20Board/Console%20IO%20Board.htm but this requires programming its two wire serial EEPROM with Parallaxes software and USB adaptor/software. Do you think that is outside the range capability of most newcomers. Alternatively we could go with a straight serial output to some dumb terminal IBM PC terminal emulator. Open also to other suggestions. John -- You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
