Re: TTL on an Apple IIe
Thanks. Open house is in two weeks. I have a Stamp here, but it will hopefully be in use that day. My problem with Pics is that I would have to order one. I don't like ordering on line because I have to borrow a credit card to do it. The same problem occurs with the super serial card. I will check into the links. The good thing is the port I want to use is already at the five volt level. Also, I will be using AppleSoft Basic to program. If there is a way to use asm, I don't know it. Basic gives me direct access to the hardware unlike modern computers though. Language should not be an issue.

FYI, the speakjet chip uses 9600 baud by default but I can configure it to take just about any baud speed. It is also 8 bit no parity ($0054) in Pic Basic.
