I think someone is thinking about 6502 assembler. When I was learning to
program, I was taught on training computers, one of which used 6502 as in
the Commodore machines. The other used the Z80 assembler as used in
Amstrad and the ZX80 among others.
My Texas TI 99 did use 9900 which was, I think, a one off.
I still have a sheet of the codes in 6502,Z80,8080 and 386, As Warren
says, versions of 386 are still used now for single processor machines.
The 6502 instruction set was simpler than Z80 and had 151 seperate
instructions compared with the Z80's 722 instructions. That was due to the
Z80 having a lot more internal registers but it was possible to get a lot
more done with fewer instructions using the Z80.
As for arcade games, I never played them though I did repair a couple.
Only monor faults like not addressing the ROM in which the games were
stored and clock faults, nothing involving the CPU.
Sorry if I'm wrong about the TSR-80. I was under the impression that it
was around about the same time as the ZX80 which Sinclair used to flood
the market i.e. 1980. He is remembered bacause he was the first to bring
home computing to your average punter and cheap too. Boy were they cheap
and nasty!
At least nether Clive Sinclair nor Alan Michael Sugar tried to control all
the world's softawre like the young William Gates. I have my own opinions
about him.
