*whoops*.
I've been mailing personal replies, instead of replies to the list. Too much
relying on procmail, I suppose.

It's a 11/53+ (aka: 1.5 MB RAM), which *should* be able to run 2.11BSD.
What OS did you manage to get Kermit running under?
Micro/RSX
I do not believe Kermit itself can handle the multiple
block sizes used
when writing the files that make up the "boot tape". Do you have any
development facilities on the currently running system? If so then it
might be possible to write a program to create a tape from the files
brought over via kermit.
There is a Macro-assembler, and reportedly a PASCAL compiler. However, my
Micro/RSX skills (let alone -programming skills) should be considered
rudimentary - the only resource I have is the on-line helpfile (which isn't
very clear every now and then).
If you've a PC with a 5.25" drive and the
ability to do image copies
to it ('dd' on a *BSD* or Linux system) that might be one way to
get 2.11 over to the MicroPDP. A single RX33 can easily hold the
standalone programs (boot, disklabel, restore, mkfs, icheck) and
it only takes 3 or 4 RX33 disks to hold a root filesystem dump.
The "RX33" is working (that's how I was able to low-level format two
MFM disks, and how I got Kermit running). And yes, I have a Minix-VMD box
with a 5.25" HD drive.
For the sake of completeness, I'll include the currently available
hardware:
KJD11-D/S (processor), DZQ11, TK50, RQDX3 with one RD32A, a third-party
21MB MFM disk (ST225, RD33? 31? Something like that), a second 21MB
MFM disk standing by (A microscribe of some sort), a 5.25" PC floppy
drive shoe-horned into a RX33, and a DELQA card.
(Well, that's what I have installed right now. I do have some other cards,
including a DRV11-J "Hi-density parallell line unit" and some strange
VG-Electronics cards (which they claim are specific to surface analysis))
And a spare TK50 mechanic..

Well... you can borrow one of my TK50s with 2.11 on it ;-)

If you need a TK50 with 2.11 on it I could produce one for you (provided
that you have jumped through all the license hoops). The only sticky
point might be shipping, where are you located? I'm travelling a lot
this month, so it may take a week or so to get it done.

Hi -
From: Martijn van Buul <pino(a)dohd.org>
*whoops*.
I've been mailing personal replies, instead of replies to the list. Too much
relying on procmail, I suppose.
;)
It's a 11/53+ (aka: 1.5 MB RAM), which *should*
be able to run 2.11BSD.
Indeed it should be able to. I personally have not done so but the
processor/mmu meet all the criteria and 1.5MB is perfect.
The "RX33" is working (that's how I was
able to low-level format two
I have a "RX33" on my 11/73 so I can create a boot disk and the
root filesystem dump (split over 3 or 4 1.2MB disk images).
For the sake of completeness, I'll include the
currently available
hardware:
Ah, thanks! That answers some other questions I was going to ask ;)
KJD11-D/S (processor), DZQ11, TK50, RQDX3 with one
RD32A, a third-party
21MB MFM disk (ST225, RD33? 31? Something like that), a second 21MB
MFM disk standing by (A microscribe of some sort), a 5.25" PC floppy
drive shoe-horned into a RX33, and a DELQA card.
It is going to take some creative symlink and mount point work to
fit 2.11 into 20MB disks - the system really expects to have ~80MB
at least for /usr. An RD54 at 159MB is more than enough but a RD53
paired with a couple RD32/3 would be adequate.
