# micro-sci-a2-controller
|
|
|
|
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)
|
|
|
|
v0.2 replaces the 2708 EPROM with a more-common 2716/2732 EPROM.
|
|
|
|
Firmware images can be built via the Makefile in the firmware subdirectory. The build framework requires cc65.
