Re: Modifying the MAX-80

I don't think so.  In case you missed it, the design in question is a Model 4
compatible, based around the Z-*2*80 processor, which is to the Z80 as the
80286 is to the 8088!  The Z-280 has a 16 MEGABYTE address space, on-chip MMU,
and lots and lots of other goodies.  The MAX design, good as it may have been,
wouldn't be ANY help building a M4 compatible system around this CPU.

A primary consideration for those working on this idea is that the existing M4
DOS (LS-DOS 6.3) be able to boot and run with no problems, assuring that the
machine will be usable and useful until specialized software to take advantage
of its special abilities is written.  Sorry, it looks like this machine WON'T
have a Model III mode.  I don't know if they've settled on a clock speed yet
or not, but Z-280's are available rated up to 25MHz!
