Apple II peeps, anyone know what DIY thing this is #retrocomputing #appleii
(my only slightly educated guess is a connector for external keyboard or joystick)

@thomasfuchs The green thing is a 20-pin ZIF socket for an IC. Not sure what the other two things are.
@thomasfuchs since so many people are saying it, no, this is 100% not for a rom.
roms are 0.6 wide not 0.3, and need data+address+control lines. Even a 256 byte chip needs 20 pins.
Both keyboard and joystick are 0.3 wide 16 pin DIP sockets.
The keyboard is a one byte input port on the databus so can't have two and a select switch.
Joystick was internal connector only, so an extension is the only way to swap joysticks without opening the lid.
@dissy614 yeah I suspected this, but haven’t seen such mods before
@thomasfuchs The internal joystick connector is a DIP socket on that side.
Before the IIe there wasn't a 9-pin on the back for it.
Are those buttons or switches?
A shift-key mod was a common thing, and a switch to choose 'reset' or 'control+reset' to trigger a soft reset
