Nope... the 100+ and 100B were (IIRC) the same thing. The B rev could
handle more memory than the 100 (the B was a motherboard rev IIRC).

The B went to 896k of memory... the 100 was less. The B or + also
had a larger power supply to handle the hard disk and more memory.

I don't remember any cost/price reduction at that time but I was mostly
a PDP11/VAX guy back then.

All Rainbows (with the correct software) could read IBM MS-DOS 40trk
160/320/180/360 floppies.

No standard Rainbows could handle the 1.2mb AT disks which came later.
