Playback adapter for CD-ROM drives - Part 2

摘要

To keep costs down, we've de-signed a single-sided PC board for this project. This board is coded 740 and measures 136mm × 97mm. The complete board and the CD-ROM drives could optionally be encased inrna plastic case or mini-tower computer case, along with the power supply.rnBecause it's single-sided, the PC board is somewhat larger than a double-sided board would be and there are quite a few wire links that have to be installed.rnBefore installing any parts though, do inspect the PC board for hairline cracks in the copper tracks or shorts. Some of the tracks are very fine and quite close together, so check carefully.
