Subject: Re: Unix for 8080/Z80? [Re: WooHoo!! PC/XT Unix anyone?]
<Any Unix clones for 8080/Z80 systems? It ought to
be doable, given that th
<original Unix was done on a 64KB address space machine...
Uzi in a 64k machine required 32k of it for the kernel
and the rest for
apps. It was a full swaping scheme so hard disk for similar was a must
have. Banking/mmu made it more palateable as you could have the kernel in
it's own space.
AFAIR (pleas correct me) there was also a multi user unix
system from ALTOS based on the Z80 - AFAIR for up to four
user terminals.
