I am a tad embarrassed! Unaccountably for me, I asked the question
before I pulled the cover. As many of you surmised it is a rebadged
Syquest SQ3105 SCSI unit. Sigh :(

>i) COPY/SYS DDO: DD1:
This needs to be followed by the
COPY/BOOT DD1:RT11FB.SYS DD1:
and then it should be bootable. As for initializing the output
tape (DD1) first, yes... that is advisable:
INIT/NOQ DD1:
However, I'm concerned by the INPUT and OUTPUT errors. The OUTPUT
error while doing the COPY/BOOT indicates that block 0 or 2-5
are bad on the output tape. These are the blocks which would
receive the boot code. The INPUT error from DD0 indicates that
they have a bad bootable tape... if it is the only copy they have,
then they really have a problem.
When the system is booting, it should be possible to interrupt
the startup command file by simply ^Cing as soon as you see the
RT11FB V04.00
bootup banner.

I happen to have a pair of Rodime 20 Plus external drives, and a Rodime
40 external. All three were bought used from Computer <mumble mumble>
(can't remember the name, some Computer place that was a big Apple dealer
in the 80's and went out of business). They had a yearly warehouse
clearance sale, where all their stores sent unsold or used/returned
items, and they sold them to the public cheap.
I think I paid $200 for the 20's and $300 for the 40, this is when the
Mac SE had just moved to the FDHD, so they weren't that bad of prices (I
think they were about 50% off the normal price)
All three still work to this day (um... ok, maybe one of the 20 megs is
dead, not sure, but I am using one of the 20's right this very minute in
the next room, and the 40, last I knew was operational... since I can't
vouch for the where abouts of the other 20, it might be dead).

I'd like to find the schematics for the DCT11-EM board (or even
better, a board based on the J-11).

3174 is just a considerably updated 3274 with more possibilities in the
software. They're functionally identical, for the most part.
As, so you're the brave one with the 4381 in the basement?

I passed along Megan's suggested COPY command to the company who are
trying to copy their one and only tape on a VT103. I have just received
the following response. Any further suggestions would be appreciated.
Out of curiousity, I asked what the machine was and whether they had any
pictures. They have kindly passed along a scan of the original brochure,
which I'll put online shortly. The VT103 is controlling a CNC milling
machine for cams. It was made by a Swiss company called Macor SA, back
in 1983. I'm not surprised they're worried about the longevity of the
tape!
--quote--
As for the copying of the tape no success as of yet, I tried the
following:
i) COPY/SYS DDO: DD1:
I tried this twice the first time the following messages appeared :-
FILES COPIED:
?MON-F-SWAP ERROR
I then tried to boot the system using using the new copy and it said:
?BOOT-F-NO BOOT ON VOLUME
The second time I tried the message was:
PIP-F-DIRECTORY INPUT ERROR DD0:
ii) COPY/BOOT RT11FB.SYS DD1:
This caused the following:
?DUP-F-OUTPUT ERROR DD1:
I don't know if this will mean anything to you but the following
messages are what is shown on the screen when the system is booting up,
I thought it might shed some light on the situation:
RT-11FB V04.00
.SET TT: SCOPE
.SET TT: WIDTH=120
.SET USR NOSWAP
.RUN ID
The last command loads up the program that's all I know, because on the
tape there are two programs ID and IDT when we want to swap between them
we press CTRL C then the message ?MON-F-SWAP ERROR appears and then we
enter RUN ID or RUN IDT
One thought I did have, do I need to format or erase the blank tape
before copying on to it?

I have finally gotten around to scanning pages 79-97 of the HP3421
user's guide. These pages contain the compact programming reference
guide. They are not pretty (darn HP (Un)Intelligent scanning software!),
but the info should be useful. They can be downloaded at

I don't think so, an equivalent duration WAV (uncompressed) or AIFF file
would be 10-15MB (maybe 6-8MB for mono).

You probably have an hp9000/310 . I typed a little about them
when I auctioned off all of mine:
http://nazas.autonoma.edu.co/hp310.htmlhttp://nazas.autonoma.edu.co/hp310orange.html
You need an HP-HIL keyboard and a monitor such as this for it:
http://nazas.autonoma.edu.co/hp35731a.jpg
In addition, you need an HPIB HD with the HPBASIC OS.
These machines are OK for instrument control, although I find
that my viper card (essentially the same system in an ISA card,
which you can then use from DOS) is far more useful.
The 9000/220 is the little sister of this one (9000/236C):
http://nazas.autonoma.edu.co/hp9836c.html
The monitors for these are very hard to come by, so a 220 without
a monitor is hardly useful. The one above, with monitor, went for
about $200 on ebay back in 2000. How much memory does it have? I think
that 220 memory could work in early hp300 models (236 memory
certainly worked).
The 200 series machines are interesting if you have the software.

These could be interesting. Can you describe them?
