[Coco] (very very slightly OT) 6800 emulator

Yes, call me masochistic..

I'm writing a 6800 chip emulator in Visual Basic :)

So far it initialises the RAM (4k), the registers, inserts some dummy 
asm code into the RAM and executes the fetch/execute cycle

Only a few opcodes have been implemented yet, but it's working

This is an exercise to get familiar with "how it all works" so I can :
a) try it in VB with the 6809, and

b) implement it in 6809 assembly to (very slowly) emulate a 6800

No, I don't know why either
