UtlimateMicro has re-released their clone of the highly sought after Apple II 3.5 “SuperDrive” Disk Controller. Known also by it’s Apple code name, the “Mustang Controller” allows you to use standard Apple 3.5 and Apple SuperDrives on your enhanced Apple IIe (and IIGS).
It’s a much better option versus the slower Liron/UniDisk 3.5 combination or VTech Universal Disk Controller (which can also be hard to find). In addition to reading Apple’s GCR format, it can also read IBM formatted MFM disks (an enabled MS-DOS file system translator required).
Available now for USD $149.99 plus shipping and handling.
