https://www.thecomputerarchive.com/Catalogs%20and%20Price%20Lists/Retail/Tan... page 19 of this Radio Shack catalog shows what looks to me like a Bernoulli 10MB drive cabinet. The 20MB drive cabinet and drives look the same but the 20MB system can only read, not write, 10MB carts. Web search "Tandy 6000, 10 meg cartridge system" found this catalog. I imagine "Bernoulli 10 MB cartridge" will be informative. Who knows if a non-Tandy controller/software can read Tandy carts? Or if the Tandy drive system was compatible with non-Tandy models (IBM, Mac, ??). http://www.retrotechnology.com/aux/iomega10.html my 10MB drive and controller and such. These are available for sale, contact me privately. regards, Herb -- Herbert R.
