[comp.unix.ultrix] Binaries on DECstation 2100?

steve@fnord.umiacs.umd.edu (Steve D. Miller) (10/17/89)

I have the feeling that this is a stupid question, but does a DECstation 2100
run the *exact* same binaries (including the kernel!) as a DECstation 3100?
Is there any followon Ultrix patch release needed for a 2100?  Now that our
DECstation Ultrix sources are in, I'd hate to buy a passel of machines for
which the sources might be somewhat useless, especially since it's kernel
hacking I'm the most worried about.

It seems to me that everything (again, including the kernel!) should be 100%
the same, since the machine is just a 3100 running at a slower clock rate and
with slower memory.  Still, I could be wrong...

Its the same kind of question that, if not asked, could lead to some
real 'gotchas.'  Information that I have been given is that the DS2100
and DS3100 share the identical machine instruction set as well as
processor (identical architectures).  If this is true, then the
binaries are interchangable.

The answer is YES.  The other day, I moved my system disk (RZ55) from my
DECstation 2100
and hooked it up to a co-worker's DECstation 3100, and successfully
booted the system off
the RZ55.

My group has been using DECStation 3100's and 2100's with the same software
for several weeks with no problems.  The only problems I've run into had
to do with color tubes vs monochrome tubes, not 3100 vs 2100.
