Hello Jay (JRJ),

I'm not sure if I understand well, what do you mean by "drawings", do you need additional images of the beast, maybe to better identify it ?
If yes :

Regarding SimH it was one of my questions in previous posts: Is there way to make bootable tapes with the data provided with SimH, apparently the answer is yes and it is excellent news ! I have never used this emulator but I will follow your suggestions and try to install the equivalent of a Nova 1200. After I do not know how to convert a disk image into a bootable tape. Regarding RDOS I see that I downloaded with SimH a file "rdos_d31.dsk", how to proceed to put this .dsk on a tape? Regarding my hardware, I have two possibilities, I'm currently working on a set of machines that I'm going to dedicate to the production of bootable media for a whole assortment of machines, I want to be able to generate floppies 8 inches, 5 1/4, 3 1/2 (DD or HD), and also 9 track tapes.

For that I have two machines:
- One is a TU81 Plus attached to a VAX 4000-505A running OpenVMS 6.2

- The other is a Shugart (KENNEDY) 9612 which can write in 800, 1600, 3200 or 6250 bpi, this tape drive is equipped with a SCSI interface but I do not know yet if I can connect this drive to a conventional Adaptec scsi interface and I do not know which program I can use. I read somewhere that Linux seems a good choice concerning the support of old tape drive, that'is right ?

Anyway, all is to make a 800 bpi bootable tape to mount on the Mag-tape Pertec 8840A of my DCC D-116(E).

Regarding the floppy drive I have a project but just started, and as usual no information, I recovered this triple 8 inches diskette drive , it is a Shugart Model 3800 (or SA3800)

I found a brochure about this:
http://bitsavers.trailing-edge.com/pdf/shugart/brochures/Shugart_SA3800_Brochure_Feb78.pdf

I do not know if there is a way to connect this machine to my D-116, I don't know if I have the required interface in the D-116, and finally I don't know anything about the interface currently present inside the SA3800. This machine was hooked to another rare machine, a "Hermes Data System 200 FD", machine currently down, and no doc, no info:
http://www.zeltrax.com/classiccmp_forum/tapetransfert/hermes_data_system_200_fd.jpg

I wanted to use the Hermes as a telex and one of these floppy drive - Although it's an SD one - for data transfer between my recent machines and my dear (still dead) Sperry Univac UTS 40, but that's another topic again, sorry, I'm scattering ;-)

FYI I still have many lacks of knowledge, I do not know what an AWS image format. I do not know anything about licensing and copywrite issues in the context of retro-computer preservation, I've always found that very inappropriate in regard of the efforts we make, the time we take on our lives to protect this legacy for the unique purpose of preserving a piece of history related to the evolution of technology. Fortunately there are people like you, in a good spirit of mutual help that goes beyond the borders of countries and continents,  a big thank you for that!

Hi all

I start here another topic concerning my research about a new Operating
System for my freshly restored DCC-116 E.

http://www.zeltrax.com/classiccmp_forum/second_boot/04.jpg
http://www.zeltrax.com/classiccmp_forum/second_boot/02.jpg

I originally intended to install RDOS on my machine but it seems very
difficult to find the files needed to make a system installation tape.

FIRST:  If you have drawings for the DCC, please let me know.  I have
two of them (long in storage in the house, but they ran when I pulled
them from their Unitote/Regitel rack a couple of *decades* ago.

There is an RDOS - disk images, available at:

http://simh.trailing-edge.com/software.html

(Top entry in the list)  It is about a 2.5MB disk image.

I suggest that you might download SimH and that image, configure SimH as
a straight Nova (rather than a /3 or /4) and see if it runs that image
OK.  If so, there you go!

Beyond that, I *might* be able to help, but it will depend on what the
status of copyright is on what I have, and whether your system can even
run what I do have.  I am looking into the copyright part of it - that
may take a week or two.  (This is something I needed to to anyway).

In the meantime:

Do you have a way to *write* a tape image?  I have an AWS format image
of an RDOS starter system.   Note, however, that the label on the RDOS
starter image I have suggests it may  only be appropriate for a NOVA 3
or NOVA 4, so it might not run on your system.    So, I'd have to take
some time to boot it and try and set up a system for a straight Nova.
As this would take several hours, I'm not keen on doing that unless you
know that one from SimH will not work for you.

I also have some OS and compiler DG floppy images, if you have a
DG-compatible floppy setup.  Several different operating systems there.
Same issue: one would have to see how many are compatible with a
straight Nova.  I have images of the floppies.

Diagnostics for DG systems are notoriously difficult to find.  I have a
few, in listing format.
