Besides having a superset of the 8088 instruction set it has an internal z80 emulator, allowing direct running of z80 software. Regards, der -------

The V20 has an 8080 mode, not a Z-80 mode. There are also various software support packages to complete the CP/M environment by making use of the V-20 processor under the MS-DOS system. I have heard of public domain ones, but not used them. I use one put out by Intersecting Concepts called Acceler8/16 (not public domain). I then run M-80/L-80, DDT, etc. under that. I haven't yet tried BDS-C, but I think it should work. Acceler8/16 also includes a software simulator of the 8080, so you can do the same thing without an NEC V-20 processor. This works fine, too, but is of course a lot slower. You can also get MS-DOS cross compilers that produce 8080 or real Z-80 code. I know Aztec makes (or made) one. I've seen it but I don't have it myself. Bob Clements CLEMENTS@BBN.ARPA {ihnp4, linus, decvax}!bbncca!clements K1BC @ K1BC Everything above is the trademark of somebody.
