If anyone would like a copy, mail me. Is anyone else running Forth on the 6809? It's a good combination. The public domain fig-Forth for the 6809 is not so great; for example, its "*" (16x16->16 multiply) does shift 'n add to get a 32 bit product, then drops the high word. Close to 1000 cycles. Using the 6809's MUL instruction, you can cut this down considerably (83 cycles for the unsigned version). David Anderson (..uwvax!anderson)
