Hi Vince,
Could you please point us to the Makefile which "actually converts a disk
image" using SIMH to "automate the ritual of unistalling RK05 drivers and
replacing them with SerialDisk drivers"?
Ah, I seem to have misspoken. Inspecting the Makefile in .../installer,
it still runs the executable "handler_installer", which is the older
tool that more or less just hammers a new system handler and bootstrap
into place.
The script for the new installer is "sdsk". This sets up a path for the
tools, copies the newest driver binaries into the exploded disk image
(while padding them to an even block length), then imploding the
exploded directory and making a new bootable RK05 image.
Then "runbuild" is invokes, which in turn invokes SIMH and sends a
series of commands to BUILD.SV to remove various other drivers and
install the "SDSKSY" and "SDSKNS" drivers copied above. Finally, the
"BOOT" command is given to write the new second stage (and third stage)
bootstrap. The self-modified BOOT.SV is also saved as BUILT.SV.
Sorry for the confusion.
If you don't want to use diagpack2, SDSK.md is helpful, but basically
you need to edit the line:
image=diagpack2
in the sdsk script, and to have previously copied in your starting
image, and run ../tools/os8xplode on it. SDSK.md also contains
information about the need for "perl", "socat", and "expect" and to get
them (on Linux, anyway).
Oh, and the SIMH initialization file (pdp8.ini) is also firing up the
server program, so you need to tweak that to make your "foo.new"
available to the SIMH serial emulation. That script used to also
require a functioning xterm, but it doesn't any more. If you have xterm
and want to see the server log in real time, there are lines there to
invoke ../server/server the other way, and you can un-comment that and
comment out the bash line.
Once you've done all the above, it suffices to just type "pdp8" in that
directory and your new system should boot in SIMH.
Hope that helps,
Vince

The Makefile there will actually convert a disk image, and you could
just swipe the default one once it's been made.
