What files must be included in that archives. Project files or firmware maybe? If you need gerbers for pcb there is possible to be downloaded from shared OSHpark page.
Importing gerbers to CAD software to modify them is problematic. As of now I don’t think I could do it but I would be glad to be able to play a bit with it.
Ok. In reallity it will be easier to make new pcb at all. The circuit is very smple for that. Just quick reverse engineering ciruit. 2 and 3 are jumpers on pcb, also forget jumper 4 to draw on pin 2 of MCU. This jumpers I think are for STAR firmware.
