At the recent USENIX conference in Toronto, I saw a port of UNIX(tm) to
the Lisa, running with a standard line-oriented interface (a mouse driver is
included, but not used by supplied software). Perhaps more interesting,
after watching me hand-time a cc helloworld.c which took just under a
minute, the sales rep. mentioned that there would be a new, faster, hard
disk for the Lisa by the end of the year.

Part of the problem with the Lisa's "profile" disk sub-system is that
it doesn't do DMA, in spite of the existence of interfaces for that
somewhere in the back of the thing. I remember this from a talk that
Scott Bryan of UniSoft gave at Uni-Ops in January (February?) in Palo
Alto, CA. Scott did UniSoft's port of UNIX to the Lisa. As for a faster
UNIX, part of the problem there is the fancy graphics screen it uses.
The 68000 loses cycles scrolling it. That's why it's only 5 MHZ.
