Relay Trainer

The relay trainer is inspired by the single board microprocessor “trainers” of the 1970s / 1980s, but with a custom 8-bit CPU implemented with 83 electromechanical DPDT relays.

As with other recent relay computers, the memory is implemented in semiconductors to keep the relay count low. Microchip PIC microprocessors are used to implement this memory and the front panel user interface.

Today’s small-to-medium-sized (SMB) businesses and large enterprises are saving on their monthly communications costs by making one simple decision: to switch to a VoIP service solution from their old, outdated Plain Old Telephone Service (POTS). By choosing a new VoIP service, these companies enjoy the flexibility, reliability, call features, and audio quality that only a VoIP service can provide. Plus, they cut their phone bill by up to 70%!
