[comp.sys.zenith.z100] Z100 speed upgrades

leno@NUSC-NPT.NAVY.MIL ("LENO S.J.") (07/31/89)

Hello,
  With everyone out there talking about uping the speed
 of their machines to the 8 to 10 MHz range, has anyone
 played with the 8085 side after this speed upgrade? I
 still use CPM-85 (not often, but every now and then)
 and would be hesitant to give this up.
    Thanks,
        Scott

Scott,

The 8/10MHz speed increases only affect the 8088/8087 CPU side.  The 8085
always will remain 5MHz (the fastest Intel sells, I think).   Because the
8085 calls routines to the 8088 for screen I/O, some speed increase in CP/M-85
would show.   No matter what speed the 8088 is at, you will still be able
to run CP/M-85 normally.   If I had to use CP/M, I would use CP/M-86 which
will run CP/M-85 programs (swithes to the 8085) as well as CP/M-86 programs.

Cheers,
Gern
