Apple /// Serial card weirdness
What can you guys tell me about these Apple /// 820-0071-D (670-0129) Serial Cards? I have 3 of them and they puzzle me, especially with that giant pushbutton. I cant find any documentation about them. Are they identical to the RS-232 port on the main board but a secondary device? Need info please!
