Some classic 8-bit systems’ floppy drives (notably: Apple, Atari, Commodore) did not have an index sensor and had only one read head. As a consequence, it was possible to flip a floppy over and use it to store additional data, a capability used by commercial software and home users alike. These were called “flippy floppies” or “flippies”.
But! You can’t read the flip side of these disks in an unmodified PC drive, even if you’re using archival software like FluxEngine or GreaseWeazle. This guide shows a self-contained and reversible modification for TEAC FD55-GFR drives that enables you flip your floppies like it was the 80s again, and get both sides backed up.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
