VAX-11/730

[utzoo!decvax!shannon]

In reply to purdue!cak (Chris Kent)...
	
	1) Has anyone got UNIX running on it yet? Do the '7ZZ' ifdefs in 4.1bsd
	properly reflect a 730?

We have had 4.1bsd running on a 730 for almost a year.  The 7ZZ ifdefs
allow the CPU to work correctly.  What is missing from the 4.1bsd
distribution is any support for the IDC disk or the DMF32.  That is
currently in "field test" and will be out with 4.2bsd, if not before.
	
	2) Does anyone have any idea how fast/slow it is running 4.1? We'd like
	to put 3-4 users on it, if that's not unreasonable, but would probably
	live with it being just 'standalone troff'.

It is about half the speed of a 750, 30% of a 780.  Much of
the "speed" is controlled by what kind of disks you use.  We
used RK07's at first and they were so slow I could hardly stand
it.  Now we have a UDA50 on ours and it is actually quite usable.
We have not yet had enough experience with the IDC disks to know
for sure how they will effect performance, but since the RL02 is
about the same speed as an RK07 and the R80 is the same speed as
an RA80 (or RM80, they are all the same drive), you can make a
reasonable guess.  Another caveat - we have not had much multi-user
experience with it.

3-4 users sounds reasonable, but probably not if there is a heavy
troff load as well.
