Apple II Mystery Card
I received a mint Apple IIe, 3 5.25" drives, a cassette drive, light pen and a bajillion other disks / cables / peripherals over the holidays, and I'm going through all this stuff.
Anyway, when I opened it up, there is a disk controller card in slot 6, and a Proclock card in slot 4. In slot 1, there was a very plain-looking card, and I cannot tell what it does, or what it's for. On the back, it has "(C) 1984 Dunrich Computer Products Inc." and "SLOT 1" on the back. On the front, it has a 20pin male hookup (similar to that on a floppy disk controller card) and there are 3 chips and a capacitor on it, the largest chip says, "MC6821P" and "M9N8419" on it. It was made in Canada, and is a very aquamarine colour.
Google wasn't much help here. Any ideas?
BAH - it occurred to me about 30sec after I posted this that I'm an idiot, this is probably a printer adapter card. Wow, do I suck.
