Another option would be to spin the data onto LINCtape with a TD8E, then
mount the result on the PDP-12. I think Dave is creating the images in
the first place with either a TD8E, or possibly a custom controller.
I folded in the SerialDisk changes from Bob and from CJL back in
January, as well as the new boot loader from Doug and various other
fixes in February, including support for systems without the KIE
instruction. Kyle approved and merged my pull requests, so that should
all be there for you at Kyle's github:
The current version should have no problems with the 8/I or with the
PDP-12. (Maybe even the straight-8, but I can't remember checking if it
is "increment and rotate" clean. Doug might know.)
