I tested the three C64s i got and none are getting video on a known working
composite monitor. im also not getting a beep when i try ^G (assuming a
speaker is inside the computer) do these systems need an rf modulator or
require a tv?

>Could someone provide a quick tutorial on how the process works?
All you need is one page out of the RT-11 manuals: that for COPY/DEV/FI.
As an example, if you've got a RX02 that you want an image of, and you're
going to put that image on a RL02 and call it "MYRX02.DSK", you do:
COPY/DEVICE/FILE DY0: DL0:MYRX02.DSK
Then you use Kermit (or, if you're like me and have a half-dozen networked
PDP-11's, you just use FTP) to move the image off to whatever other place
you might want to put the image.
To do the reverse operation, you'd (or course!) do:
COPY/FILE/DEVICE DL0:MYRX02.DSK DY0:
Note that doing this under RT-11, you *only* get the blocks that RT-11
usually addresses on the disk. There are the usual caveats about
track zero on 8" floppies and the bad block forwarding table on RL02's;
these are well-discussed in the RT-11 _Software Support Manual_ in
the sections on individual drivers, and the .SPFUN ways of reading
these areas are also thoroughly documented.
Also note that in doing this, you'll be copying every block on the disk,
even those not included in a file. Don't get burned like some others
have and end up copying proprietary or personal data that you didn't
want copied when you make the image! Bob Schor has a program called
"CLEAR.SAV", that is available from the 11S113 RT DECUS SIG symposium
tape, that will clear out blocks not allocated to a file. This, and
many other useful utilities from Bob, are available from:
ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/rt/decus…

A buddy of mine is packing up to move and asked me if I'd like to take a "bunch
of computer junk" off his hands. Now that I have it home, I find I have:
1 commodore 64.
1 composite monitor for a 64.
1 1541 floppy drive.
1 Sekosia(?) printer with a C=64 interface.
1 vic 1600 modem.
1 Apple Printer.
lots of manuals and stuff for the 2e I bought from him earlier.
lots of manuals, cartriges, and software for the 64.
I haven't had a chance to test anything but the printer, which appears to
work (although as usual my GS doesn't seem to LIKE it much. I may wind up
switching back to my epson lx800 with that machine.)
Once I've tested the 64 and whatnot to make sure it works, and messed about
with the software I always wanted to have but could never afford, I'm probably
going to get rid of it. And I can't quite put my finger on why, since I was
a '64 owner until 1990. Maybe its that I would miss the custom hardware I had.
Or that I can't imagine going back to a 60 column screen. Or the non-standard
interfaces for EVERYTHING on it. I dunno. Does it make sense that I wouldn't
be nostalgic for the machine I actually owned, as opposed to the apple2s?
*shrug*
Anyway. Just a heads up for you Commodore folk out there. :)

Hi Jason,
I can't precisely identify what you have but I've got a navarone cartridge
connector somewhere in my collection. They were a small company and
the connector I have allow you to have 3 cartridges connected to the TI99/4a
at once. there was a switch to select the cartridge that you wanted to be
active and a reset button if I remember correctly. This allow you to
switch cartridges *without* reseting the computer or putting too much
wear on your cartridges. This was very useful in certain circumstances
such as when using the assembler cartridge. You wolld use it in this
way to examine the workings of ther cartridges.
Maybe your device serves a somewhat similar function.

I was just watching a thing on robots and they mentioned some of the early
80s attempts. Does anyone have in their collection a H.E.R.O, or other robots
of that vintage?

In a message dated 98-09-10 23:23:46 EDT, you write:
<<
I have just acquired several large pieces of equipment and I have some
questions about them. I haven't moved them yet- some of these
questions concern moving them.
What I have are an IBM System 34 (model 5340), an IBM System 36 (model
5360), two tape drives (model 8809-1C), and two printers (model 3262-B1),
plus some manuals and tapes. Everything is supposed to be in working
order- they upgraded and pulled the plug.
1. How much do these things weigh? The computer person there estimated
2000 lb. for the 34, 1000 lb. for the 36, 700 lb. on the printers and 500
lb. on the tape drives. Does that sound about right?
The weights are about right. A good loading dock or a good forklift is
necessary.
2. How possible is partial dismantling for transport? I didn't get to
tear into them to look. Loading access is fairly good in the building
they are in, but unloading the 34 could be tricky. It would help if I
could lighten them up.
Genarally they are on wheels and are not taken apart to be moved. I don't know
the configuation of the 34. It is possible it could be composed of several
parts, but looking at the model number I think it is one piece.. I have moved
several of these systems and usually I rent a truck with a railgate type of
liftgate on it. These have a larger deck and ride flatter. Hopefully the truck
matches the dock. Use a flat dock plate. If there is a mismatch put a piece of
sheet steel over the dock plate to reate a smooth surface to roll on. IBM made
a little wire U shaped clip (bent at the bottom of the U) that is used to keep
the wheels from rolling. This can hold the unit still untill you can tie it
down. Remember there is lots of mass involved. It is best to tie off each
machine.
3. What needs to be done before moving? Head locking, moving or removing
anything, stuff like that.
At each corner near the wheels are leveling screws. these need to be raised
with a crescent wrench, all the way up.
Other less important stuff that I'm curious about:
4. What kind of interface does it have to the terminals?
5. What kind of power does it need? I'd assume 3 phase 220v.
It could be single phase.
6. How much computing power is this? Compared to a VAX 11/750, say.
7. How will these things tolerate living in an unheated building over
winter? I live in IL.
They should survive if you don't try to power them up. They want to be warm to
run.
Any other hints and tips would be greatly appreciated. I'd really like to
be able to move these machines without damage (to the machines or me).
I went there today mainly as a recon mission, but they convinced me to
take home a Wang word processing system. The server is a model OIS-60X,
and it has 4 terminals hooked up by RS336 (?) over coax (BNC connectors),
plus a laser printer. I think the printer weighs more than the server.
I got a bunch of cartridges for it, and some Canon copier cartridges too,
"because they're almost the same". I think not.
>>
If the Laser printer is an LDP-8 then the Canon Carts should work. The engine
is a Canon SX I think.
When or IF you get rid of it, im very interested in that monitor.

Nope step 8 is language inquery and if it's not printing a list to
respond to then the halt button is in. Step 9 is identify the terminal.
If the terminal cannot or does not respond I belive it will continue.
Do check the settings of the halt and run buttons and The switches on the
rear pannel.

Similar save for VAXstation was the marketing thing for a workstation
configuration and Microvax generally meant terminals for IO unless there
was a /GPX or /SPX then it was a workstation. Confused... so was
marketing.

The RD53 has a problem, there is internally a rubber bumper and the head
is stuck to it! Common problem on the Micropolus 1325s. The fix, open it
HDA, unlatch the head lock and force the arm to move then apply power and
close. recover data and dispose or if you nuts like me do surgery to
remove the peice of gum that used to be rubber and button it up and use it
a few more years.
< Cycling 'HALT' on the front panel causes the usual 'break' monitor

I think it's waiting for a terminal.

This snippet I grabbed last year as I was compiling my Commodore 8-bit write
up for Vintage Computer Festival 1.0 at least it's a lead... (my scrapbook
doesn't get cleaned much) I think it was a writeup on an awards ceremony for
the innovators of the microcomputer industry.
> One of the awards went to William D. Mensch, Jr., president and CEO, The Western
> Design Center Inc. Mensch was fundamental to the development of the Motorola
> 68000 microprocessor, and he went on to help invent and develop the 6502 chip at
> MOS Technology in the early 1970s. The 6502 was eventually used in Apple,
> Commodore and Atari computers.
>
> The second award in the category was presented to Chuck Peddle, president, Thstyme
> Ltd., and another MOS Technology veteran. Peddle pioneered the phenomenally
> successful 6502 microprocessor, and, under Commodore, led the development of one
> of the first personal computers: the PET (Personal Electronic Transactor), which put the
> 6502 chip to practical use.
Hope that helps!
