- I assume you are talking about building a RS-232 serial port and a
- Centronics compatible parallel port for your 8bit directly from the SIO
- port. Sorry to say, but you will be major money ahead to buy something
- like the P:R: Connection. The SIO port doesn't have the correct voltages
- or data lines to simply assemble a cable with a SIO connector on one end
- and a RS-232 connector on the other end.
-
- Going from a RS-232 line to a SIO device (as in the ST-Xformer) is another
- story. It is much easier to drop from RS-232 12volt signals to SIO 5volt
- signals, AND not too much more than the data lines and software polling
- signals are needed to send/receive from SIO devices.
