New subject: SCO Free OpenServer and UnixWare

Hi, I'm interested in buying old hardware like PDP-11, VAX,
Sun, etc., if possible near Italy (or in E.U.).  Can someone
subscribed to this list suggest me [someone|a company|a university] that
sells this type of hardware, please?

Regards,
	Sandro

I just received this email from Frank Wortner. Anybody have a copy of PDP-11
Xenix?

I've sent off email to a friend of mine who preserved some materials from a
now-defunct software company we used to work for.  He *might* have that
tape.  I regret not keeping track of it,  but fifteen years have elapsed
since I last booted it.

Too bad.  PDP-11 Xenix had a number of nice features.

o It was based on the Seventh Edition.
o It ran on everything from a PDP-11/23 on up.
o It could simulate split instruction and data space on non I&D machines.
(*)
o It had a complete shutdown procedure (an elaborate /etc/shutdown script)
o The kernel was delivered as an archive library (".a" file),  so you could
reconfigure without source.

Perhaps someone at SCO (or Microsoft) may still have a tape of it.  Most
software firms archive their products in secure vaults,  so it might still
exist in some warehouse.

(*) The scheme involved paging the instructions while the data remained
resident.  The first 8K of the program was always resident and contained a
jump table and supporting software.  The next 8K held whatever instructions
were executing at the time,  while the remaining 48K was reserved for the
data and stack segments.  Building a simulated I&D executable required the
user to link once as a pure executable,  once as a split executable, and
finally running both executables through a program which built the final
simulated split I&D executable.  The compiler had an option ('-j' if I
recall correctly) that performed these three links automatically.

Sorry for the rambling note,  but I'm just a bit overwhelmed by nostalgia.

Well yes, sorta.  It's on the net, John Wilson has it on ftp.dbit.com.  The 
however is it's for the PRO350/380 systems.  I don't know if it can be moved 
to more standard PDP-11 configurations.

I don't think John has it at ftp.dbit.com.  And I doubt that XENIX is
anywhere on the net.  I don't even know if there was a PDP-11 XENIX. (It
was originally MS, afterall.  They "sold" it to SCO way back, before SCO
collected everything else.)

There is, however, VENIX (no commercial relation to XENIX other than a
common parent) on ftp.update.uu.se.  This version of XENIX is for the
DEC Pro350/380, which is, essentially, a PDP-11.  There was also a VENIX
for "real" PDP-11s.
