A fairly quiet day

Not done a lot today - tweaked the assembler so the changes I made yesterday are the same - I've also made the assembler generate code in TMS1x00 PC order, rather than normal counter order so I don't have to maintain two lots of code, but it's still flattened in the emulator so it looks normal.

Thanks to Sean's scan of the output PLA I know that the mapping of O register -> O lines is 1:1 on Vegas Slots, need to check the physical wiring tomorrow - I do have a couple of Microvisions and most of the cartridges made.

Oddly MB seem to have made different cartridge designs rather than just two - a TMS1100 and an Intel8021 one.
