> 2.) Can it be done without a tape? If so, has
anybody pulled it off?
A ~32mb disk is going to be very tight for any 2BSD
system. V7 will
fit I think.
But does V7 have a MSCP disk driver? Recommending to someone that all they
have to do is write a driver when they don't even have a running machine yet
is, IMHO, a bit optimistic :-).
Of course, under the Mentec PDP-11 hobbyist program he could install
RT-11 or RSX-11 or MicroRSTS on such a machine quite nicely from a bunch
of RX50 or RX33 floppies he made from the Mentec CD-ROM's.
> 3.) Are there any utilities, either DOS or
UNIX/Linux/FreeBSD based, to write

Hmmm, I thought John Wilson has some utilities that
could do that.
See ftp://ftp.dbit.com/pub/putr/
How many RX50's would it take to hold a root filesystem dump? 15 or so?
It's not *quite* as cruel as the RX01 root distribution we discussed over
some Pastrami sandwiches a couple of years back. But it is approaching the
"Wagner Ring cycle on convenient 45's" stage!
On the other hand if the controller is an RQDX3 it is
possible with
some luck (and more hardware skill than I have ;)) hook up a standard
5.25" Teac floppy drive. I don't have the location of the info for
that at hand - you might try the alt.sys.pdp11 or vmsnet.pdp-11
newsgroups (lots of knowing folks hang out there).
See ftp://ftp.spc.edu/third-party-disks.txt
See, it's these sorts of references we need in the PUPS FAQ list. The
same questions come up every month, I give the same pointers, then everybody
forgets them again, until I answer the same questions the next month :-).

Hi,
is a location known where this may be preserved? This should be
an Algol68S (P.Hibbard) compiler from CMU adapted for V7 Unix in Manitoba.
At least, Andy Walker calls the beast 'Manitoba compiler'. See recent
discussion in comp.lang.misc.

Is it freely available or requires a license? Regardless, I'd be happy
to put it in to the PDP-11/Applications area in our Unix Archive.

Hi -
From: SHOPPA(a)enterprise.trailing-edge.com
But does V7 have a MSCP disk driver? Recommending to someone that all they
Oops - I messed up there didn't I? Concentrated so much on the size
of the disk I forgot about the MSCPness of the device :(
Ummm, as a matter of fact no it doesn't. Depending what version
of V7 you have it may or may not even have an RL driver.
How many RX50's would it take to hold a root
filesystem dump? 15 or so?
Oh perhaps 8 or 9. Using RX33 disks it only took 4 floppies but
the RX50 is what, 400kb (about 1/3 that of the RX33).
It's more like just Siegfried on 45's rather than the entire Ring ;)
Is ftp.spc.edu still up and running? I know spc11c.spc.edu is out of
action and I'm not sure home much longer the systems at SPC.EDU will
keep running now that Terry's no longer there.
