I can't speak for all of the amforth'ers, but I can tell you what I do. I have a set of words (in assembler) that support the Microchip 25LC512 serial EEPROM. These words allow me to save and restore a full system image on my ATmega328P. By "full system image" I mean flash from 0 to dp and EEPROM from 0 to edp.
I have modified my amforth file to detect a low state on a given I/O pin at reset. If the pin is low, the amforth startup code refreshes flash and EEPROM from the serial EEPROM, then performs a normal startup. It takes about three seconds to do a system save and about 0.5 seconds to do a restore on reset. Makes life a lot easier during development. However, this does not answer one of your implied questions. I still have to download my programs under development using the serial port. There is enough leftover serial EEPROM to hold at least 32 Forth screens, but I have not been able to hook the serial EEPROM contents into the Forth interpreter. Key words, such as LOAD and BLK are missing, which means the interpreter cannot switch between interpreting from TIB and interpreting from a buffer. If these changes are made, I would be able to develop on the target. Until then, it's the old-fashioned way. I'm looking into how best to make the needed changes, but guidance from the amforth community would be most welcome.
