Attn: Hams! Need help with CW/RTTY software for C64 or Apple II

Hi, gang. Over the weekend, I picked up an old audio-to-TTL or RS-232 interface at a hamfest (AEA CP-1, for those of you who know what it is....) with joystick-port TTL cable, but no RS-232 components installed. (That might be a project for later, since I have the book/schemo/parts list). I want to use either one of my C-64's or one of my IIe's with the interface, but I lack the necessary software. Since we all love old software, and I know several of us are hams, I figured this would be as good a place as any to start looking. If I can't find anything, I'll try installing the RS-232 components to the motherboard and see if I can get a regular serial port to work and try it on my pc. But I'd really rather use the older machines for this. CW receive/decode is a priority, since I can still send with a paddle, and I'd like to try decoding some RTTY if possible. Can anyone help?
