Unidentified Hardware

KDS Interface for the Amstrad

KDS Interface for the Amstrad - there is some confusion on this device.

Some people say it'd be a serial interface - this may be true, but it's definetly NOT the KDS Electronics Serial Interface (which has a 50pin connector).
The device looks quite similar to the KDS 8-Bit Printer Port but with an additional cable attached to it, which isn't attached (or isn't visible) on the 8bit port photo, Media:KDS8Bit.jpg.

Actually, the KDS 8-Bit Printer Port should require a similar cable (for 5V power supply, which isn't available on the CPCs 34pin printer port). So it's quite possible that the "KDS Interface" and "KDS 8-Bit Printer Port" are the same hardware, both having the cable, but with the cable being not visible on one of the photos for whatever reason.
