Either LSI11/03 or 11/23 CPU card
M7264 or M8186, respectively
64K RAM (I forget the name - it's the standard
M8044 card - is that an
MSV11?). Maybe more than one on an 11/23 system
MSV11-D was 32KW (64KB) Ram (up to 4 can be used)
DLV11-J quad serial port (one for the console, 3 for
the user)
M8043
LPV11 printer port
M8027
IBV11 GPIB interface
Don't remember off-hand... there was no standard RT-11
device handler for it...
Either RXV11 (RX01 floppy drives), RXV21 (RX02 floppy
drives) or RLV11
(hard disk) controller
RXV11 M7946
RXV21 M8029
RLV11 M8013/M8014 (Q/CD)
In the far left slot there's a BDV11

Hello gang,
I just unloaded and sorted out 5 boxes of documentation and a little
cabinet with 2 RL02's.
The documentation :
a full set of RSX-11M 4.0 binders
an incomplete (?) of RT-11 5.1 manuals, I got no's 1A, 1B, 2A,
2B, 2D, 3A and 3B (which ones do I miss besides 2C?)
a set of boxes for the Professional 300 (CPM/80, HD system,
diskette system, Install & maintenance and Communication disk)
a set of 7 grey binders for the Professional (Developpers
Toolkit 4.1)
a grey binder for the Professional (Dev. Graphics Toolkit)
an incomplete set of MINC-11 docs, missing book 4 and 6 from
the set of 8 (dates 1978)
Some course books for RT-11 (User, Programmer and Programmer
Administrator).
The 2 RL02's worked without a problem (except the squeeking sounds
when they got started, I guess they didn't run for a while :=).
One of these drives has a little switch inside which allows you to
use the drive either as an RL01 or as an RL02!
With some luck I might be able to pick up 1.5 Kennedy tape drive
and a genuine DEC tape unit (don't know it's model etc).

Hi Ed,
I have a set of RT-11 5.1 manuals too. In vol. 1A do you have the "Guide to
RT-11 Documentation". That gives a complete inventory of the manual set on
page 2. There should be one for the RSX-11M set too in its respective
"Guide to..." manual.
Here's my RT-11 5.1 volume list: 1A, 1B, 1C, 2A, 2B, 2C, 3A and finally,
3B. You apparently are missing vol. 1C which is the System Generation
Guide, an important vol. if you plan to do much work with RT-11. Therefore,
just vols 2C and 1C are missing from your set.
The Dutch (or European) manual set may be somewhat different. There is no
vol. 2D in my 5.1 set. 2C has the System Message Manual and the Keypad
Editor User's Guide in a single binder. Could there be a different editor
or something in the Dutch/European set causing a volume 2D?
Let me know if you have other questions on my RT-11 set Ed.
Megan, have you any comment on the diffs between my 5.1 set and Ed's?
Big congratulations on scoring this haul of documentation!
Regards, Chris

New subject: RT-11 manuals Was: Re: Latest finds
Hello Chris,
There is 'Guide To ..' but it was still in it's shrinkwrap, and it was
not in the firts binder, in fact, it was placed at the end of binder
3B.
It seems that the European version is a little different, it lists
binders no. 1A, 1B, 1C, 2A, 2B, 2C, 2D, 3A nd 3B. The manual 2D does
contain the KED editor guide. It looks that the System Messages were
part of a separate binder. So, only thing I miss is the SYSGEN and the
System Messages guide.
Unfortunately I do not have the RT-11 SW yet, I'm still looking
for it (on RL02, anybody able to help me here :=) ).
Best regards,
Ed

One of these drives has a little switch inside
which allows you to
use the drive either as an RL01 or as an RL02!
That's an unofficial mod that is reasonably common. Basically, the switch
changes the link settings on the logic and DC servo boards to make the
drive behave as an RL01.
Watch out, though. The RL02 heads write a narrower track than the RL01
heads, and if you write to an RL01 pack in your drive, it's possible that
a real RL01 won't be able to read it. Reading RL01 packs is safe, though.

The DEC FS guy that showed me a drive that he had mod-ed also mentioned
that the same set of switches he flipped, also included a "force write

Disclaimer: I have never installed this mod on any DEC drive, but it sounds
pretty safe. YMMV.

Based on Ethan's and Tony's information, what are then the differences
between both types, just the track width (i.e. size of the head) and a
few jumpers on the locig board? Or is there more?

More exactly, there exist some models of RL02's and RL01's that have
identical boards, different heads and three or five jumpers that are different.
There are also drives that have boards that are *not* interchangable.
You must check part numbers to be sure.

New subject: RT-11 manuals Was: Re: Latest finds
Megan, have you any comment on the diffs between my 5.1
set and Ed's?
I can't really comment... I may still have a few docs from the V2C
days, but since then, working in the RT group, I couldn't maintain
a copy of each doc set (along with all the other pdp-11 docs I had)
so I only kept a copy of the most up to date (and one version
behind that).
I used to work in the Mill... when the RT group was moved to another
facility about a mile away, I had to pare down my collection, and
at that it took 90 boxes to move my office. Later, when the RT
group was assimilated into the Ultrix development group, we were
told to throw out everything pdp-11 related... I didn't. But I did
have to pare things down a little more. That move took about 60
boxes to move my office.
As it is nowadays, I only have a copy of the V5.6 documentation, and
the release notes for V5.7. And most of my pdp-11 documentation
(what is left) has been moved home...
I still have my collection of handbooks for pdp8s, pdp11s and early
vaxen... three boxes worth of them.
