It was cross-checked with a Franklin-branded board, as well as the (belatedly discovered) official Franklin schematic (included in doc/service_and_schematics.pdf) +Since it is a faithful clone, it requires a 2708 EPROM (or a different EPROM with a 2708 adaptor). A board slightly revised to use a 2716/2732 is available on the 2716 git branch. + Firmware images can be built via the Makefile in the firmware subdirectory. The build framework requires cc65. ![usci](usci.png?raw=true "usci")
