@ -4,6 +4,8 @@ This is a clone of the Micro-SCI / Franklin floppy drive controller.
v0.1 is a direct clone, reverse-engineered from a Micro-SCI board. 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.
