I have been told that the Atari 400 is incapable of supporting a 1200 baud modem. Anyone know if this is true or not. I don't see why it wouldn't. Does anyone know what the pin configuration for a standard RS-232 25 pin connector is? I.e. pin 4 data send etc. Finally, I see adverts all the time from Radio Shack for replacement keyboards, however I have yet to see one that they make that will connect to my 400. Can you alter the output pins from the keyboard to match the Atari? Is there a full stroke keyboard around that will connect to the 400? (Other than the b-key). Dave

The 400 does support a 1200 baud modem, currently you need either the
ATARI 850 or PR connection.

I purchased one of the Radio Shack Keyboards once-- when they had ADAM remnants. The reason you can't do it easily is that all keyboards, in general, are matrixed differently. Computers send a certain number of lines out to their keyboards, and require a certain number of lines of responses. These lines vary from computer to computer. For example, an Atari Keyboard might sense a letter "J" when it sends out on it's first line and receives a signal on its first input line. Another Keyboard might put "J" somewhere else entirely. Furthermore, even writing a translator program is difficult, because different keyboards have different numbers of input and output lines. Does this mean you're stuck? Of course not. There are lots of mail order places that you can order real Atari keyboards from. I'm sure the other people on the net who know what these places are would be happy to tell you.

You can buy any keyboard with spst switching and rewire it according to the schematic for the atari keyboard. While a bit tedious it does work.
