CCR-81 cassette drive: - portable, extra batteries available from any shop - storage cassettes available from shops and thrift stores - no need for linux or any software skills - user friendly interface, great for beginners - uses standard cassette drive cable, or alternatively a DIN adapter cable - Large size, not easily forgotten on the coffee shop table
