I am finally ready to load a disk image onto a RK05 disk for my
PDP-11/10. I have RK05 disk images for RSTS-11 (my goal).
What is the easiest way to load the disk image onto a RK05 cartridge?
I was thinking of using vtserver to transfer the image over a serial
line, but the 'copy' program is not compatible with my PDP-11/05 (it
uses the 'mul' and 'div' instructions which is not available on my
PDP-11/10).
Here is what I have available:
PDP-11/10 with 32kw core memory
serial connection (max 2400 baud)
RK05 (non-bootable cartridge but does load properly)
external dual TU58 DecTapeII drive
Many thanks for any information. I am really looking for a nudge in
the right direction. ;-)

Is this the same reason why I cant get vtserver to work with my
PDP-11/04 and PDP-11/34? Has anybody else had success with this?
Has anybody considered a guaranteel clean version of vtserver that 'just
ran' on all PDP-11 hardware (or is that a pipedream)?

We really need some enterprising person to spend a weekend hacking
on vtserver. Extend the file size limitations, support more target
processors, etc. I'd love to do it myself, but as with everyone
else, no time.

Well, I've been working (slowly, in my _spare_ spare time) on a Windows
version of VTServer (I know there is one out there, but it never worked
for me). I'm basically porting the original C code over to C# and doing
some severe cleanup/refactoring/etc. Getting rid of the 32mb limit was
one goal, I wasn't aware of the processor limitation, but I think that
would be worthwhile too. (And it should run fine on any system that can
run Mono, so I'm not leaving you Unix guys out, honest...)
One of these days I'll finish it...

I've used it on an 11/34. It works fine. It won't work on an 11/44 due
to console issues (the console is not a clear channel).
I have not tried it on anything else.
Later this summer I plan to have an 11/34 with RK05's and a SCSI card
and I'd be happy to load up RK05's for anyone; but I'd like to
borrow/buy/trade-for an alignment disk first, just to be careful.

Well, IIRC, vtserver requires an MMU and >32kW of ram, though I don't
remember how much exactly.
So, that pretty much excludes anything less than an 11/23, or some
higher numbered models without an MMU or enough memory installed.

I haven't exhaustively searched for such instructions, but a sample
multiplication found in the C source didn't turn into a mul
instruction. You sure this is the cause?
