Default Re: INS8073 - What I wanted, but never got.

I was more interested in the ins8070 and the additional instructions compared to the ins8060. The ins8070 includes stack operations and also multiply and divide, so it would be interesting to see if this made programming any easier and then if it made the ins8070 more competitive against the 6502 or z80.

It has a similar bus interface to the ins8060, removing cont, ads, si and sout to allow a full 16 bit address bus, instead of multiplexing the top 4 bits of address with the data bus. It should have similar multiprocessor option as the ins8060, but not sure if that could be used from the onboard basic of the ins8073.
