Data General also had a delightful small two reel 7" tape drive also. Used
with the Nova series of computers
BASF Endura is good tape. It shouldn't delaminate.
When I got boxes of new tape I looked for a reseller in the back of Processor
Magazine that specializes in tape. Shipping is a killer though.
I was never able to sell a box of 7" reels of tape (1200') though. No one
wanted them.
