There’s plenty of fun to be had with retrocomputers of yesteryear, but for modern users, it can be something of a culture shock. Going back to floppy disks after all these years is a reminder of just how far storage technology has come in terms of speed, reliability, and of course, capacity. Luckily, there are ways to combine the best of both worlds.
Floppy drive emulators for classic computers are of course nothing new, but we think this one [c0pperdragon] has put together is worthy of a closer look. Not only does the ATmega32U4 based emulator have an exceptionally low part count, but the code has been written in the Arduino IDE. Both features make it easy for new players to duplicate and revise the design should they feel so inclined. In a pinch you could even implement it on a breadboard with a garden variety Arduino.
The emulator is housed in a 3D printed enclosure designed to look like an era-appropriate Atari 1050 Disk Drive, except you’re using SD cards instead of floppies. The firmware can mimic two physical drives and supports up to 100 disk images on each SD card. The user interface is about as simple as it gets, with two push buttons and a pair of seven-segment LEDs to indicate which disk image is currently loaded up.
We’ve seen some very elaborate disk emulators over the years, but there’s something compelling about how straightforward this version is. If it helps a few more people experience the unique joys of retrocomputing, it’s a win in our book.
