Yep, but with the 1991 date on the ad, it makes sense that they might have been trying to expand the market into that territory. It'd be a second HDD for those models, where on a Plus its obvious utility would be the primary/boot disk role. It makes little sense to me in either case, as a ZFP drive puts the CRT at a less neck hostile height.
Coupled with a CD/SC however, the Bacster would make for a very nice Plus setup indeed! :approve:
