Clock port which can be used for faster Serial, parallel port/s or for a sound card and you can also buy a board which goes on the clock port so you can use 4 devices on the port. or below is what was really intended for the port,



A1200 clock port interfaces:

PortJnr - 460Kbps serial interface
PortPlus - 2x460Kbps serial & 800kB/s parallel i/f
IOBlix-12S - 1.5Mbps serial interface
IOBlix-12P - EPP parallel port interface

This soundcard will plug into the A1200's realtime clock port along with a connection terminal in the rear expansion booth. It has almost all the features of the 'big' Prelude, e.g. true 44100 and 48000 Hz fullduplex, a multi channel mixer, record level adjustment, etc.

The Prelude1200 comes with a special connection terminal made to fit inside the A1200's rear expansion bay. The audio output as well as three inputs are available externally. A fifth internal connector can be used to route CD-ROM audio through Prelude's mixer. One of the external inputs will be directly connected to the output as long as the card is uninitialised. This is ideal for connecting the original Amiga output so that you don't need to replug any cables just to play old bootloading games which do not use the soundcard driver.

In case you want to build your Prelude 1200 into a tower converted A1200 there's a special customized slot bracket available which will carry the connector board.
