Absolutely true.

On the other hand, if you need to do some CP/M-80 development, this may 
still be the system for you.

The V20 normally executes 8088 instructions and indeed the V20 plugs
directly into an 8088 socket with no problems (executing slightly
faster, by the way).  But with a special instruction, the V20 can be 
made to execute 8080 instructions.

I know of an entire 8080/Z80 development that was done on a standard 
set of PCs using this mechanism.  They replaced the 8080s with NEC V20s 
and used a Shareware program called V2080 to allow them to run CP/M 
utilities under it.

Instead of fighting over the single SBC prototype to compile and debug,
they were able to run a CP/M-80 c compiler and do unit testing from their
desks using their PCs.  Quite a productivity increase.

E-mail me if you want a copy of V2080.  I think I can dig it up.
