That 6809 bewitched my middle school self. Having already learnt Z80 assembly language, the 6809 just looked so much more elegant. It had index registers that were actually useful! It had position independent code! It could do multiplication in one instruction! So when faced with choosing a CoCo or a C64 .. of course I chose the machine with the MUL instruction. Naturally, within mere months, that horrid 32x16 black on green display forced the harsh realization that a computer is more than just the CPU, that the support chips could actually be far more interesting. Who cares about a multiply instruction, when you could have sprites and 3 voice sound? |
