A&J MicroDrive System-100
The A&J MicroDrive System-100 is a tape drive almost identical to the Exatron Stringy Floppy.
A&J was a company that spun off from Exatron. Initially they sold tape drives with the same drive mechanisms and cassettes (called "wafers") as the Exatron Stringy Floppy, then switched to a different drive and wafer from BSR that is conceptually and essentially the same merely with slightly different dimensions. The BSR drives & wafers are not compatible with the Stringy Floppy.
The same drive was sold in at least a few other products for other platforms. Two known examples are the Rotronics WafaDrive for the Spectrum, and the Quick Data Drive Model 8500 for Commodor 64, and a Quick Data Drive rebadged by NCS.
The wafers were made & sold by Entrepo, and also rebadged by at least Phonemark and Smith Corona.
