ReCIA-AVR
About the ReCIA-AVR PCB
ReCIA-AVR is an open source PCB design by jbilander, published on GitHub. It is a 2-layer board measuring 17.4 × 51.4 mm, with 27 components from 15 distinct parts.
Other key parts include the AVR128DA64-I_MR, 74AHCT1G17, TLC2932AIPWR and 8520_DIP. By type, the board carries 13 capacitors, 7 resistors, 4 ICs, 2 inductors and 1 connector.
It belongs with the retro computing designs in this gallery.

A drop in replacement CIA for old Amiga Computers
This is WORK IN PROGRESS. If you generate gerbers and order PCBs from this source you are doing so completely at your own risk!.
Current design is based on an intel/altera 10 Max FPGA but this is mostly so we can signal tap and record how a real 8520 behaves. The oscillator on board is 10 MHz and the PLL on the Max 10 can take this clock and make a perfect 28.375 MHz or a 28.636 MHz clock signal which will be nice to base the logic on instead of the E-CLK.
