Better means any feature that would bias one towards one computer
versus another. Did it include a z80, by any chance? On the back
of this machine, there were some slot covers; did it take standard
apple cards?

amazing amount of information on the Tandy site! They should be proud
of themselves, considering someone was actually paid for typing this
stuff up!

Subject: RL02 slides & brackets
Hello All,
Who can help me with a pair of RL01/RL02 slides and the 4 brackets?
I want to mount my 3rd RL unit in the cabinet but don't have a 3rd
pair of them.
A payment can be discussed.
Thanks,
Ed

I certainly think that any electronic computing machine is appropriate
here.

Keep in mind that early RQDX3 revisions don't know how to talk to
RX33's - they're limited to RX50 floppies. Seeing as how your system
is apparently doing bizarre things with the RX33's, this might be the
case.
What exactly do your "RX33's" do when you try to access them?
What firmware revision is your RQDX3?

Yes.

To get RT-11 to deal with two DU controllers, you can either:
1. Do a SYSGEN to create a DU handler that can handle more than one
DU controller. With recent enough RT-11's, the same handler
copes very nicely with multi-port booting.
2. COPY DU[X].SYS to another name (say, DG[X].SYS), and then SET DG:CSR=nnnnnn
and SET DG:VECTOR=nnn, where nnnnnn is the CSR and nnn is an unused
vector in your system. When you create a bootable floppy which you
want to be bootable on your second controller, you must lay down the
DG bootstrap instead of DU, since the DU device points to the wrong
controller.
The tradeoffs between the above two methods are documented in the
RT-11 _System Generation Guide_ and the RT-11 _Device Handlers Manual_.
Method #2 above is easily the quickest, and will probably do just fine
for your purposes. (Though a RT-11 system with extended-unit multiport
DU handler is a beautiful sight!)

Look for the file MUB.COM on your distribution:
! COPYRIGHT 1989, 1990 BY DIGITAL EQUIPMENT CORPORATION
! ALL RIGHTS RESERVED
!
! MUB.COM command file used to build binary kits
Again, it will depend on which version of RT-11 you're running whether
MUB.COM is MU-bootability is present.

I had to trade back some RQDX2s for RQDX1s on some PDP-11/73s I delivered
to the gummint because RT-11 didn't support them. I don't recall which
version we were using; it would have been at least 5.0. I remember
grumbling about how fancy (read "bloated") RT-11 was getting, but I don't
recall doing _that_ until 5.2; I thought it happened during the 11/73
incident, though. I also don't remember why I thought 5.2 was bloated
(it may have been the UCL/UCF stuff, which I thought was unnecessary),
but I did stash away a 5.0 distribution kit as a hedge against bloatation.

Yes, the UCL stuff is unnecessary, which is why if you don't want it
you simply answer SYSGEN question 100 with "NO":
100. Do you want the user command linkage (Y)? $
USER COMMAND LINKAGE OPTION:
The user command linkage allows you to define your own commands
which can be issued in a format similar to the standard DCL
commands.
100. Do you want the user command linkage (Y)? NO
> but I did stash away a 5.0 distribution kit as a hedge against bloatation.
An even better hedge against bloatation is to get RT-11 5.6 or later
and learn how to use SET RUN VBGEXE. No matter how big the monitors
and drivers grow, by appropriately setting a .SAV image's VBGEXE
bits you can give it access to "all" 56kbytes of virtual memory space. If you
want direct access to I/O space, you can turn that on too, or you can
also elect to have 64kbytes of virtual memory space available to your
process if you don't need direct access to I/O space.

Found an old modem that I forgot I owned and was just wondering a few things.
First, it's a Concord Data Systems 224 ARQ/Autodial that I now remember was
in tow by a 3B2 I picked up a while ago. Anyway, it's rather heavy (humongous
hat sink on back) so i opened it up and began to think that the innards seemed a
bit complicated for a 'modem.'
OK, I'll admit it, I was 11 years old when these things would have been in use,
but I have other modems from the peiod ('85-'86) that aren't nearly as complex.
It's about the size of a large book and has three levels of circuit boards
with a
Z80 CPU, an SIO chip, and memory chips (one says "zeropower (tm) ram" on
it and "DO NOT DISPOSE OF IN FIRE!!!!") on one level, Intel 8031 series chips
on another and who knows what on the bottom (haven't taken it all apart yet).
Not to mention the 32 dip switches (all off) and the 23 led's on the front.
To make a long story short, what did/does this thing do that a regular modem
of the time didn't do?
Thanks,
les
