I've got the service manual that I used to use when I
supported them. I still have a couple of drives though
so I don't want to lose it. I could make a copy given
enough time (it must be ~200 pages). I was planning
to do that at some point since there's someone else
on the list that I promised a copy to (I'll have to dig
up that message to find out who).
Do they have an urgent need or are they just trying
to prepare for when they need it?

Opps, I missed that URL. It's late (early?) and
I thought it was part of your digital signature.
I'll follow up on it myself.......

Now a question for the real wiered stuff:
Does anybody know a Wang-71 ?
I just know the name - I'm right now on a trace of
a specific Russian computer, and they told me that
this machine is a Wang-71 clone, but I can't find any
information about this machine. No, I have no pictures
of the Russian machine and no further data. The clone
is build 1975, so the original design might me a bit
earlyer.

P.S.: has anyone a list of PDP-clones ? I want to
classify some finds.

I am not familiar enough with both machines to make a judjement on which one
is better but the franklin display some features that seem interesting:
apple dos 3.3 compatibility, floating point basic, apparently could run CP/M
or Pascal (OS?)(not much info on that), programmable function keysimpressive
display capabilities (16 colors at 560 x 192), built in parallel and serial
interfaces and memory expandable up to 576K.
Compare that to the Apple IIe or IIc. The memory extension and RGB interface
cards are optional (128K and 80 column color?)
It's hard to tell what the exact caracteristics are the users manual keep
refering to the technical manual that I don't have.

A computer museum in The Netherlands is looking for the documentation for
a Kennedy 9300 tape drive. I'm sure someone on this list has that.

Since you've got a WQESD, you've got two choices with respect to
partitioning:
1: Hardware partitioning.
Partition your 150 Mbyte drive into multiple 65536-blocks drive
through the WQESD firmware. You don't need to do a reformat from
scratch; just redefine the disk structure and write it to disk.
2: Software partitioning.
Partition from RT-11. Assuming your drive is at LUN 0, you
already have the default mappings SET DU0:UNIT=0 and SET DU0:PART=0.
The "UNIT" refers to the MSCP LUN of the drive, and the PART
refers to the software partition number.
Map DU1: to be the second logical partition on the first MSCP
LUN with SET DU1:UNIT=0 followed by SET DU1:PART=1.
Continue on up until you've used up all the disk. Each PART
refers to a logical partition on disk, each of which is 65536
blocks long (except for the last one, which is whatever is left
over.) Of course, only the first 65535 blocks of each partition
are directly usable, given RT-11's block numbering scheme.
SHOW DEV:DU will show you the current partitioning.
Keep in mind that if DU is your system disk, you'll have to do
a reboot to reload the driver with the "new" partition settings
before they'll go into effect. (You wouldn't believe the number
of RT-11 5.7 field test sites who complained "partitioning doesn't
work" when they simply failed to reboot after the SET DU's! This
has been in the manuals for over a decade!) After rebooting, INIT
DU1:, etc., and away you go!
Since you *do* have the WQESD, I heavily recommend that you do your
partitioning at the WQESD level and not at the RT-11 level. This way
all your partitions will be hardware bootable. If you do the
partitioning through RT-11, the resulting logical partitions won't
be hardware bootable.
A neat tool (hey, I wrote it, I think it's neat) for looking at MSCP-
level stuff under RT-11 is the DUSTAT program, available from
ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/rt/dusta…

By default, if your disk is larger than 65535 blocks, the physical unit
numbers for the DU device map to partition zero (0-65534) of the
selected physical unit. If you want to map another unit of the DU
handler to another partition, you issue the command:
SET DUn UNIT=m part=p
where 'n' is the RT-11 unit number, 'm' is the physical unit number in
your MSCP configuration, and 'p' is the partition number (starting at
zero).
For example, say I have an RQDX3 with an RD54 (169mb) and an RX50
(dual drive):
DU0 = Partition zero (0-65534) on phys unit 0 (rd54)
DU1 = First of the RX50 drives
DU2 = Second of the RX50 drives
If I want address more of the RD54, I can do the following:
DU0 = Partition zero (0-65534) on phys unit 0 (rd54)
DU1 = First of the RX50 drives
DU2 = Second of the RX50 drives
DU3 = unassigned
DU4 = Partition one on phys unit 0
(set du4 unit=0 part=1)
DU5 = Partition two on phys unit 0
(set du5 unit=0 part=2)
DU6 = Partition three on phys unit 0
(set du6 unit=0 part=3)
DU7 = Partition four on phys unit 0
(set du7 unit=0 part=4)
This is, in fact, how many partitions you would get on an RD54. All
of the partitions except the last one will be full 65535 block units.
The last one is about 7k blocks.

p.s. I forgot... after doing all these SET commands, you'll have to
reboot for them to take affect.

I checked the storeroom at school today to discover that all the old
Tandy equipment (which had collected dust there for 2 years) has been
disposed of. Not even a keyboard left. All I could find is an
assortment of Apple II GSes, drives, Imagewriters etc & a few old Mac
LCs.
Sorry, I remember those old Tandys - 2 labs worth. (used 86-96). They
even had an Apple Emulation card (Trackstar) since at that time no one
in education could imagine using anything besides an Apple.
