Image them with what hardware?  A PC or one of my TRS-80's?

I will look for that.  I used to have some nice DiskZap programs
but have been unable to find any of them.  At least not on a disk
I can still access.  :-(

I didn't try typing in a program but I got the "READY" prompt.
I thought you had to have MODELA/III and be able to load it to
get to BASIC on a 4P.  I would be very surprised that while it
could not boot TRSDOS it could somehow load MODELA/III from the
floppy.
