Here is a pointer to a freeware implementation of Forth to run on a C84: ftp://ftp.taygeta.com/pub/Forth/Misc/F2PIC.EXE It is a small implementation, unusually byte rather than word based, but does have some rs232 support and words to write to and read from internal eeprom. ( I have nothing to do with the compiler, just thought one or two of you might be interested. ) Regards, Mike Watson
