Apple ProFile, Apple Widget, Sun20 these parallel port hard drives use a proprietary interface protocol to connect to historically important Apple computers, namely: Apple Lisa aka Lisa 1 Lisa 2Lisa 210 aka Macintosh XL Apple ][ Apple As the original drives are now 20+ years old and new repairparts are long unavailable, it is no wonder that the number of working units is dwindling. This style of hard drive is essential for most Lisa operating environments and the Apple SOS, so a solution was sought to maintain operability of these legacy computers. We set out to develop a longterm solution to this problem, with emphasis on maximum compatibility, flexibility, and performance. The result is the XProFile.
