David - sure can.  What you'll need to do is to hook up one at first (as /d1)
so that you can still boot from the 40tk drive until you've gen'd up a new 80tk
bootdisk.

The L-II disk has the descriptors needed, I think.  Something like "d1_80ds.dd"
or similar.  Or use "dmode /d1 sid=2 cyl=50 stp=3"  to make any /d1 double
sided, $50 cylinders (80tks), and 6ms step rate.

Hardware-wise, you should be able to just set the jumpers to the drive number,
and for HM instead of HS (head load on motor, not select), and plug it in.

Get them, then yell for help if needed.  At least half the people here must be
using them, altho perhaps have forgotten over time what they did to make a new
boot .  Like me.  - kev
