This board is popularly known as the Model F blue-switch and is also the only Model F that has a solenoid .
From all who use this board, need some pointers on its conversion.
On ebay https://www.ebay.com/itm/163734585116 I see there is a converter that looks like a promicro converter (?). If anyone has these, would you be able to confirm what chip this is and what firmware is on it?
Alternatively, what are the other options to convert these?
