Oh there are: Miniscribe (early Maxtor) 8051A (40MB, voice coil) supports XT or AT mode. Seagate in either: ST325A/X or ST351A/X (quiet stepper but pretty good).

And Tandy have website for every all the way back to early models. Search for it with www.metacrawler.com By the way, squash the thoughts of getting IE installed. Get Netscape 3.04 gold (very reliable, appox 15MB total) and seperate email program like Pegasus Mail (under 1MB), suitable programs for mail use. Netscape 4.x is too new and too bloated for current crop of late 486's and most pentiums. Real bad program is IE 4.x which breaks everything especially angering those notebook owners.
