Schematics for remote

Postby Hastor » Sun Nov 03, 2019 8:24 pm

I saw in a message board where someone mentioned they were able to get the schematics for the remote from Rich. I'm not finding a way to contact him directly, but does anyone (or Rich if you're watching) have access to this? Of course I'd buy a new one from the source if they were still around, but would be ok to make my own like the other person did.

I'm using a IIGS so I spent a while thinking I didn't need one, bringing up the system menu to access the card and change disks. However, I've found that some games either prevent access to this menu, or freeze after opening the menu and returning to the game.

Yeah I actually figured that out eventually, forgot to post here. I have one now. I thought the whole shop was down, but apparently that's the only thing in stock. Works great!

Here is a link to the remote schematic.

http://dreher.net/projects/CFforAppleII ... Remote.pdf

Notes:
1) The remote uses a technique called Charlie-plexing.
2) The zero Ohm resistors are not needed, this was a hold over from some design choices that were not needed.
3) U1 was an attempt to minimize ESD going back into the CFFA3000 and could be removed.
