SDrive-MAX Upgrade

Description

Upgrade your existing SDrive-MAX to allow it to be used together with physical drives on the SIO chain.

The SDrive-MAX did not work well if it was not the only device on the SIO bus, but thanks to Bernd Herale there is now a modification that can be made that will allow the happy co-existence of both the SDrive-MAX and physical floppy drives together.

This upgrade is designed for anyone who bought our SDrive-MAX’s after December 2018 and includes the following:

• SDrive-MAX SIO Mod PCB

Please send your original drive, and your new order number back to:
Vintage Computer Center
373 E. Shaw Ave. #178
Fresno, CA 93710

If you have a drive we produced prior to December 2018 we suggest this upgrade as it will also provide a much higher quality case and SIO cable.

The daughter board is thanks to the great PCB design work of Steve Boswell if you want to build your own check out his UNO2SIO page.
