From: Jules Richardson <julesrichardsonuk at yahoo.co.uk> Xenix would certainly run in 1MB of memory. That is...at least on the i286 (512K was the minimum when I was subjected to Xenix). As I recall, it ran in even less on the 8086. On the Tandy 16 (68000), I *think* it ran in 256K, but please don't hold me to that. I understand that it also ran on the z8000, but I never saw that. I don't recall ever seeing that Xenix was ported to the 32016 for any machine. BSD4 was, of course, among other Unixen of dubious lineage. Considering the bugs, it's amazing any of them worked. Of course...why you would want to run Xenix on something other than a PoS system, other than to say you did, is a bit beyond me...;-)
