Has any ever thought of writing simulators for the two missing systems, the
PDP-5 and the PDP-12?
The PDP-5 is almost identical to a PDP-8, except the program
counter is in memory location zero.
The PDP-12 is

Well, for those NOT running VMS in simulation, but wanting
to get at some archival programs, I finally figured out how to
make vmsbackup work. First, you need to extract the backup
save set from the tape container file, so it is just a stream of
bytes, without the block size and file mark
From: Al Kossow a...@bitsavers.org
Is there any particular reason you are inventing ANOTHER tape container format?
Well, because I figured out how to do it. Is there a place where this
format
is documented? Is it compatible with Linux binary files? This scheme
is really
minimal.
Well, I am now really close to having a mag tape drive working on
a Linux system. The docs confused me, so the bit ordering is
backwards. That will be easy to fix. It is not detecting file marks,
they just show up as zero-length records. I'll have to track that
down.
What I will do next is

Hello,
I want to use the pdp-11 sim of simh to teach my kids some
machine-language programming.
I have it compiled and running on a Linux system. When using
interactive deposit
in the PDP-11 simulator, it increments by single byte addresses, so you
get :
