Xenix on the Acorn 32016

An update to the comments of last week: I retrieved my source listing of the linker for Panos last night, and buried in the middle of it was a commented-out section for handling object files from Xenix-32000. So I guess at some point Acorn was indeed looking at Xenix for that platform. I do sort of have a vague recollection of some involvement with Logica. I suspect this was one of those one-man projects where the only Acorn person involved was the manager. Maybe Dave Lamkin, or his boss whose name escapes me for now. (Mike someone?) By the way the Panos linker is 3/4in thick fanfold and quite a bit to scan. I guess I'll do it sometime but it's not a priority; I've been having much more fun recently scanning Edinburgh University documents detailing the operation of both the PDP9/15 systems, and the Interdata 74's. In recent weeks I've scanned the sources of an operating system for the Interdatas ("Legos") and a BIOS for an ICL 7502 remote job entry terminal which Edinburgh University managed to turn into a serviceable computer. Also the documentation for the High Level Assembler used on both these systems. (We already had the source of the assemblers, just no docs or predef files.) The Edinburgh collection is getting quite impressive. We also have recovered locally written operating systems for the PDP9 and PDP15, two O/Ses for PDP11s, Perkin Elmer 32bit, 68000s and of course the big one, EMAS for ICL29XX and IBM mainframe architectures of various flavours.
