GottFA80 - a Gottlieb System80 MPU based on a low cost FPGA
This is a 1:1 functional replacement to a original Gottlieb System80/System80B MPU, without the additional features of a LISY80, but with much faster boot and lower costs. You can build a GottFA80 for less than 70 Euros!
I have four versions at the moment
based on CycloneII FPGA, cheap but 'later' 80B games are not supported
based on Bversion 1.0 but with JLC preassembling service
based on CycloneIV FPGA, 'later' 80B games supported but unfortunately the FPGA board is not available at the moment.
