* Some information fragments are here: [[Cirkit]].
== Technical ==
* I/O ports are unknown...?
* Chipset: uses 8251 UART (according to the advert)
* Note - Cirkit reportedly also made a "Twin-port" serial interface (which probably used other chipset)

== Specs (from advert) ==
* Plugs into Disk Drive, through Bus Connector for Disk Drives and other peripherals.
* Can be used to interface to other RS232 devices, such as Modems, Plotters and Printers.
* Baud rates supported 75/1200, 1200/1200 and 300/300
* INPUTS:- Data, one handshake - RS232 compatible
* OUTPUTS:- Data, one handshake - +5 volt positive going Works with all TTL level inputs and most RS232 devices.
* All interface features are software addressable, uses 8251 UART.
* Supplied with full RSX drivers, which may be used in your own programs.
* Not directly compatible with Amstrad CPM.
* Extensive documentation about interface and RSX's supplied on cassette.
