====== Prototype Board (Rev3) for RC2014 ======

ProtoRC3 (**Proto**type for **RC**2014, Rev**3**) is a 100mm x 76mm perf board with an Altera EPM7064S CPLD prewired to a [[http://rc2014.co.uk/|RC2014]] bus. The 5V programmable logic is flexible and has sufficient logic to handle a varieties of designs. ProtoRC3 is designed for through-hole components.

===== ProtoRC3 Designs =====

==== CRC65 Prototype ====

The first [[builderpages:plasmo:protorc3:crc65proto|CRC65 was prototyped]] using ProtoRC3. It is a frugal single board computer based on 65C02. This is the [[builderpages:plasmo:crc65|homepage for CRC65]]. Discussion about CRC65 can be found here:
