Hardware test: Building a serial/parallel loopback adapter
Adam Wilson is an electrical engineer who reworks old electronics in his spare time. In his blog he reports about his work with old computers, about the expansion of his collection and the repairs or restorations he has carried out.

In the latest blog entry, he documents building some serial/parallel loopback adapters for easy diagnostics using Keir Fraser's Amiga Test Kit Software. "Loopback testing" involves sending transmitted electrical signals back to the transmitter so that the transmitter can check its own output. In communication (e.g. parallel and serial modems) the output of the transceiver must be connected to its own input - if the device gets its own output signal back, this proves that it works. (dr)
