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. Leonard Young KS4RN From: n8vem...@googlegroups.com [mailto:n8vem...@googlegroups.com] On Behalf Of monahanz Guys, I thinking of trying to solve the chicken/egg problem by doing a single Z80 based S100 board that would contain 64K RAM, EEPROM, PS/2 keyboard input as well as a host of indicator LED's and jumpers to deactivate ROM/RAM keyboard etc. one at a time as other boards are added to get new people started on the S100 bus. 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 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 -- |
