I recently got an Apple 2 ( a pal one ) and I have some unknown boards inside. I absolutely don't know why these board are used for.
Here are some info about them :
- AMPEX ASSY 3586600 with a stickers where " Host Adapter for Apple IIe " is wrote on it. It ends with a 50pin connector at the back of the computer. It's plugged on port 4.
- One with a stickers where " LPV1 " is wrote on port 1. It ends by a "Centronic 50 pin" connector.
- One with a stickers where " Jumper for high resolution monitor " is wrote on it. It's on slot 3.
If someone could tell me what they are and how they are used it would be very nice :).
