The Beta computer

The Beta computer is a small but fully functional 6502 system. Ideal for controlling applications! The base, called ‘controller’, is a PCB with 6502 cpu, a 6532 RIOT and a 2716 EPROM. A really minimal 6502 system with lots of I/O and a minimal IC count.

This standard controller is meant to be inserted in a PCB called ‘terminal’ on which specific hardware can be placed, depending on the application.

Two ‘terminals’ have been described in the original articles, one acting as a development system, with KIM-1 like seven segment LED display, hex keyboard and an EPROM programmer. The second ‘terminal is a smaller board with a relay to switch a load and temperature sensor and also a keyboard and LED display. Besides the original articles, scanned and in dutch, the most relevant information on this system is shown, including source of the monitor.
