Hi, Does anyone happen to know the model of 5.25" drives used on the System 4 (or 3 or 5)?

Cheers

VintageAcorn.com suggests that the System 5 shipped with Tandon TM101 drives (96tpi, double-sided 80-track) but the System 5 handbook (in the power supply load section) mentions Olivetti, Shugart and Tandon drives.

For anyone looking for older floppy drive information (in my case 5 1/4" Full height drives) this is a pretty good resource

Ps. if anyone out there has any fully height acorn system compatible (80 track, 96 TPI, double sided) drives they want to donate to a good cause or sell - please let me know. :D
