I don't think VMware will run Win95 or Win98. If that is wrong,
I'd sure like to know, as I could pack up an ancient system I
still keep around for archival reasons.
I realize that no one else may be using the Symbolic Debugger
(SD: - specifically SDHX.SYS) in RT-11, but there is an
enhancement that should be helpful and I could use some
This question will probably receive opposite answers since
this group is so diverse. BUT here goes:
The questions is (as described below): "Should all 6 possible
SET commands be available or is that too confusing to the
user and only the first 4 SET commands should be available?"
In RT-11, a user program can issue an EMT request so that
RT-11 allows the user program to handle TRAPs to locations
4 and 10 so that special expected error conditions can be
However, in the RT-11 Symbolic Debugger, these TRAPs
are again over-ridden unless the user again forces them back
to the user program with the commands:
_T4;V let the user program handle TRAPs to 4
_T10;V let the user program handle TRAPs to 10
For turning off either selection (if either was selected), the
;V turns off both TRAPs to 4 and 10
Unfortunately, the DEC version Y01.16 of SD: always
required the user to first activate the Symbolic Debugger in
order to execute one or both of those commands. However,
by adding two additional SET commands to the SD: code, the
user can use these SET commands (even in a command file to
automatically initialize everything) before the SD: code is
even LOADED and activated, as for example:
SET SD: T4 - equivalent to _T4;V
SET SD: T10 - equivalent to _T10;V
Turning off the selections uses the commands (the commands
are only almost equivalent to ;V):
SET SD: NO T4 - ONLY turns off _T4;V
SET SD: NO T10 - ONLY turns off _T10;V
Of course, it is also possible to have two more SET
SET SD: TRAPS - equivalent to both _T4;V and _T10;V
SET SD: NO TRAPS - equivalent to ;V
The questions is: "Should all 6 possible SET commands
be available or is that too confusing to the user and only
the first 4 SET commands should be available?"
By the way, although it is not very useful to re-implement the
current SET commands so that the change is applied after
the LOAD SD: command has been executed, it is possible
to add code to the "SET SD: T4" option which changes
both the SY:SDX.SYS file and any copy which is in memory.
This allows the user to execute "SHOW CONFIGURATION"
without having to first "SET SD: BREAK". In addition, the
"SET SD: T4" command can then be done either before or
after the "LOAD SD:" command.
Another other comments or suggestions would also be helpful.

Does this mean you have other tapes in the tray? If so, could you

I can OCR and email it to Al to save him time. Do you have any other
of these documents that can be scanned? David G. may want to put all
of your images/PDFs on his site too.
I have some questions about Televideo 955 terminal.
The manual lists a serie of options, among others the ability of emulate
tek 40xx graphic terminals.
I'm interested in this feature, but it's not clear to me if a particular
version of the terminal, or a particular board is needed.
Furthermore, the manual pictures two different motherboards, normal and
extended, but what it's the difference?
Finally, there's a way to identify the hardware / software options of the
terminal with some key combination, our some special command?
Firstly, if you've seen my message about this on VCForums, then I apologise for the redundancy.
I've spent the best part of 4 years getting my Ohio Scientific C24P working. The biggest problem being the MPI drive unit of which I've replaced and fixed many parts. I think I now have everything working, but don't have any bootable media to test it with. I was wondering if there was anyone here who would be willing to make me some copies of OS65D on 5.25" media?
Thought I'd share my site with you. I restore/recondition M's despite
their condition. It's a labor of love for these fantastic mechanical
The site is at http://www.phosphorglow.net/
If you are in need of a lovingly reconditioned M or need yours restored,
please mosey over to my corner of the interwebs.
I also have a small army of classic computers in my personal collection
that will be making their appearance when I get the time to play with them.

We have a CNC controlled DEC (motherboard M 8189 picture -0).
Please submit an offer for the replacement of the emulator with DECtape-II (Fig. 1.2, 3) for loading the data from the memory card, USB stick, or propose another solution which allows us to make technical backup data cartridges (DECtape-II photo 1).
If you need more information or photos please write.
We appreciate the timely development of our inquiry.

I've got a 2400' reel of 9-track tape here from 1971--so far, no issues.
But the brand is "Wabash"--I'm well acquainted with the execrable
quality of the brand when it comes to floppies, but have no experience
with pre-floppy-era tapes.
I'll bake the thing (130F for a day or so) before reading it, but does
anyone have any experience with this brand and age? I'd used mostly 3M,
CDC and IBM branded tape back in the day.
