The Apple II Universal Controller, not to be confused with the Video Technology UDC card is equivalent to the Apple IIc Plus SmartPort, where as the Liron card is the Apple //c SmartPort. The Universal Controller is compatible with everything that the IIc Plus and IIgs are. It is a Double Density controller based on the IWM, 342-0041/B as the //c, IIc Plus and IIgs have on board. This card is horrendously rare, if that word is ever appropriate, it is here.

The Blue Disk can do 5.25 and 3.5 drives, DSDD and DSHD. 5.25 Disks from the Blue Disk should be considered NOT COMPATIBLE with anything else. 3.5 Double Density disks are compatible with the SuperDrive controller and AE PC Transporter only. 3.5" High Density disks are compatible where ever Apple II's can deal with high density formats.

The Blue Disk does 800K in MFM mode. These disks ARE NOT COMPATIBLE WITH ANYTHING ELSE. BlueDisk 800K is for convienence only, as you may be accustomed to 800K worth of storage when working with Apple II 3.5" disks.
