I assume you want me to look at FILDDT on the images
copied to a TOPS-10
system, correct, or is there a quick shortcut to FILDDT for a device?
Device-direct I/O is available under FILDDT. Do it from the console login so
that you're properly 1,2. If you run FILDDT and type /H to its prompt, you
will see what the options are. Basically, you want something like RPA0:/U to
start, and remember to multiply every sector number by 200 (octal) to get the
disk address right. The HOM blocks are sectors 1 and 12, so their addresses
are 200 and 2400 respectively.
Happen to have any idea how to boot one from tape?
Copy a DEC bootstrap
to the MSP disk and pray it considers one of the SCSI drives as a
supported drive?
Since DEC never supported SCSI hardware (that was done independently by SC and
XKL at different times for different hardware), that's never going to work.
I don't have an SC install manual, so I can't begin to guess how to boot from
tape. Sorry.
