With the big new Adafruit factory, and Ladyada & pt’s move to Brooklyn also complete, it’s time to turn our attention to some older projects that have fallen by the wayside. Here’s an update to our Floppsy board, it’s floppy disk-shaped and is intended to be a fully open hardware / open source interface to archive diskettes. This version adds Apple Disk ][ support via a 2×10 IDC connector. Thankfully we were able to recycle many of the GPIO from the classic ‘shugart’ 2×17 IDC connector for the diskII, but we had to splurge for an extra -12V bias power supply – we went for the TPS65130 a low-cost split supply generator – a nifty chip that is! this version will also support floppy disk emulation mode by letting us control the direction of the two-level shifters. An additional GPIO expander provides the 4-way button interface, which we will use for offline disk imaging.
