TapeXUM
TapeXUM is a USB device that can read and write to cassettes of Commodore 16/64/VIC-20 (read and write) and ZX Spectrum (read only) format. It requires a Commodore datasette connected to it. This project is based on ZoomTape by Arnd Menge, a great idea and originally a part of OpenCBM package. TapeXUM uses Arduino Pro Micro and through hole components so it's a DIY friendly design.
Huge thanks to Data/Tropyx for creating enclosure design for 3D printing!
Changes in software (since ZoomTape)
- modified device firmware to support Arduino Pro Micro
- added ability to continue tape capture even if stopped (before that, read was interrupted once datasette playback had stopped i.e. with Stop button)
- added azimuth adjustment feature (prepare your screwdriver)
