This project is used to dump the ROM of a vintage MOSTEK 3870 microcontroller. A ATMEGA1284P microcontroller is used to drive the MK3870 in a manner where the ROM contents can be captured. The schematic directory contains the KiCad drawings of the electrical circuit, and the software director contains the software to be loaded onto the ATMEGA1284P. PlatformIO is used to compile the AVR code.
This project was heavily inspired by Sean Riddle's solution to the same problem.
To use, simply build the circuit provided in the schematic directory, and then run the software as described in the software directory. It is a good idea to test with a MOSTEK 38P70 that has a EPROM attached containing known contents so as to verify the system is working before attaching the target MK3870 with the unknown ROM contents.
Use as you see fit. Attribution would be appreciated.
