A DiskVaccuum For Obsolete Disk Formats

drive

[Jim] has a box of disks for a very old Compucolor II computer, and with bit rot slowly setting in he figured it might be time to dump all those disks to a more permanent format. After reviewing the existing tools to read these disks, he decided to build his own floppy disk interface that he calls the DiskVaccuum.

The DiskVaccuum is based on a Papilio Pro FPGA board and a few chips worth of level conversion. The FPGA is able to read bits and move the head of the disk with ease, saving everything to the drive of a much more modern computer.

On the USB side of the Papilio board, [Jim] wrote a shell of sorts in Python to capture tracks on the disk, read out the track listing, save an image file, and do all the things a proper DOS should. Right now the project is only for the Compucolor II disk drive, but [Jim] played around with KiCAD enough to create a Papilio-to-disk-drive interface board with connectors for most of the disk drives of this particular vintage. The hope is to generalize the hardware and software to read disks for other systems, including those with 8-inch drives.

[Jim] put up a video describing the hardware and demoing his Python capture utility. You can check that out below.
