I have used the PIC32 version in a number of project, as a VT100 terminal, works very well, it also cheaper to build that the propeller version... Full source code is available and is well documented... Easy to program the PIC32, or you can order a pre-program chip....

Tom Lafleur (858) 759-9692 I agree that this sounds really cool. I'm also in the "yes, please, serial port" camp. I haven't seen a VT100 built from ATMega's, but I recently built this VT100 that's based on a PIC32: http://geoffg.net/terminal.html - it turned out great. Serial in + PS/2 keyboard, VGA and composite video out, all driven from the PIC32's internal D/A. Only a few bucks in parts (most of the $ in the connectors).

I second the preference the others have for the serial port. Less clutter on the desk (one screen and keyboard less if you have a laptop) and allows for xmodem, PC logging and additional peripherals to be connected in the future.

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
