* 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 possibly likely, The possible that the "KDS Interface" and "KDS 8-Bit Printer Port" are the same hardware, and do both have having the cable, but with the cable being not visible on one of the photos for whatever reason.
