mike@edstb.UUCP asked about the difficulty of porting minix to Zenith's
Z-100.  Since the only similarity between the Z-100 and the IBM PC is
that they both run the same cpu chip, it looks to me like all of the
device drivers will need to be re-invented.  We may be able to use the
Zenith rom for simple things like screen output, but anything dealing
with interrupts will probably need to bypass the rom.  A floppy-only
Z-100 lacks a dma controller.  I plan to add a dma chip to my homebrew
SCSI disk interface.  Does anyone know if Zenith's hard disk controller
does dma?

Are there any other Z-100 owners out there who want to run minix?  I
will be taking a shot at porting minix to my Z-100 as soon as I get
organized and acquire a copy of the book and software.
