PB-501 Logic Design Trainer
The low cost PB-501 Logic Trainer permits students of digital electronics to make efficient use of valuable laboratory time. Circuits such as clocks, switches and lights are permanent parts of the PB-501 and need not be repeatedly constructed. Students build only those circuits which directly pertain to a particular experiment. Everything required to design and experiment with logic circuitry is included in the PB-501. Power is supplied by either four 1.5 V batteries or an optional AC adapter. The PB-501 is housed in a tough molded plastic carrying case with an integral hinged cover which stacks conveniently for storage.
