This is a little circuit to connect your MD or DAT to your CD-ROM drive with standard optical cable.. Parts cost about 50 FIM. This circuit is tested by me with no problems with locking to signal. Sources were Creative Infra CDROM and Creative Labs AWE32 soundcard. Recording device was SHARP MS-200H Minidisc.
In my computer circuit is powered from free floppydisk powercable (Black ones are GND and Red is +5V). S/PDIF output in AWE is the 0 pin of the S/PDIF connector.
