Hi Christian, Glad it worked.
> How much of 256KB flash is effectively usable with AmForth on the 2560? ? Good question. I don't know. The file avr8/words/store-i_big.asm may give some clues. > Will this work as well on a Chinese ATmega2560ProMini (with FTDI USB chip > for terminal input) ? Again, I don't know. However, if the board has an ATmega2560 mcu running at 16 MHz then there is good chance. I think only by flashing the board and testing it will you have a better idea. > If so, may I share your links with a friend who has an ATmega2560ProMini? Yes.
