Gorat80
Gottlieb Rom and Test for System80
This is a project back from 2016. By placing Gorat80 into the 'TC1 Adapter' of your Gottlieb System80 MPU you can test your Gottlieb MPU and even replace game and/or system rom.
The adapter is controlled by a PIC ( PIC16F688(DIL14) ). You need to program the PIC with the hex file provided! This can be done e.g. with a PICKIT3 ( Note: you need to use 'High Voltage Mode' )
Roms can be placed on a 27C256 (32 KByte) Eprom
Note: The LEDs do have integrated resistors, do not use standard LEDs!
