Actually, I meant the RL02 terminator. I have been entering bootstrap
code by hand since one of my bootstrap ROMs went pins-up a couple of
weeks ago - you may remember I posted asking about favoured boot ROM
images? Not to mention entering quite a lot of code into ODT by hand
when I first got my 11/73 and *nothing* would play nicely...
Originally the Baydel multipurpose card could boot pretty much any
common QBus mass storage.

Terminator not required save for those with boot proms on them. However
a bootable 11/03 only needs memory, console and RX01/2 and the willingness
to use ODT to enter about 30 words of boot code by hand. Allison wrote:
I just paid about ?30 for some PDP11/03 boards, CPU, MXV11 and some kind
of serial card (can't remember the exact type). I had a BA23 lying around
empty, and an RQDX3. Now I need some media...
Alternatively, anyone got an RXV21, RL02 cable and terminator they can
sell me?
Gordon. Minix on PDP11, Not that I know of. It would be
interesting.
Well I think Minix #1, would be easy to port, but why? You got real
unix.
It just proves how effective code on the 11 could be. Too bad you can't
buy
a pdp-11 cpu chip for $2.49 like a 8088. I take it is still rather pricy
to put together
a basic 11. Any body know how much? The RQDX will need the distribution board to breakout
the floppy and HD
connection from the 50pin cable. If you find prints it's something
that can be wire wrapped (it's only connectors). The boot for MSCP
disks is also possible to hand enter.
Got the breakout board, in the BA23. Haven't played with it yet though.
