Data Recorder Arduino UNO Cassette / Tape Dump CMT remote control for vintage computers
An Arduino UNO R3 (ATmega328) project.
Arduino code by Mr. Takuya Matsubara.
A complete solution to playback and record old tapes using a micro SD card (8GB or smaller, default FAT - no subfolders).
The board can connect vintage computers with a CMT cable (data recorder connector) and manage REMOTE MOTOR control.
It can playback binary files (tape dumps) from the SD card and save binaries from WAV (or authentic FSK signal coming from a tape) to the media.
Tested and compatible with the following vintage computers:
- NEC PC-6001mkII [.CAS / .P6]
- [further to come...]
Main features:
- Arduino UNO layout
- Minimal BOM list for a cost-effective solution
- Wide LCD display
- Speaker for listening FSK during the operation
- Push buttons and fine-tuning for options selection
- No need to make any conversion / post processing using a mobile app
- Automatic REMOTE (motor) control for single and multi load games
