Any thoughts?
Assuming that the new disk doesn't have any bad blocks in its bad block
table that aren't on the original disk :), my first suggestion would be
to write a small PDP11 assembly program to read a bunch of blocks from
one pack, and write them out to another pack (with a lot of swapping).
It'd be tedious, but you could hand assemble a program (or use macro11
on another system) and enter it in using ODT... but you'd be limited to
reading and writing no more than about 55kB at a time, which would mean
about 20 pack swaps.
The other option I can think of, is that you could change the unit number
on one of your RL02's, either by snapping fingers off the ready
indicator, or (probably a better idea) sticking small plastic rods or
similar into the holes where the fingers go in the ready lamp for the
2nd RL02, and use that.
A little bit of googling or "ask-Tony" :) should help you figure out
exactly how to trick the drive into being another unit number.
