== Connecting a KC compact to a CPC+ monitor ==
These connections are known to work!
What you need:
* SCART plug
* 8-pin DIN socket
Lead connections:
* Connect the 8-pin DIN socket to the 8-pin DIN plug from the monitor
* Connect the SCART plug to the SCART socket on the back of the KC Compact

I read about the KC compact in the Amscene section of Amstrad Action magazine, a Future Publishing Ltd publication. From that point I was hooked and I eventually wanted to own one.
During this time I found Andreas Krueger, webmaster of the Robotron-Net website, who owned one of these computers. Andreas was very helpful and provided photocopies of a manual and the schematics, a dump of the roms, ran some tests for me and more. I want to send him a big thankyou for all the help he gave.
In the last few months (May 2001) I contacted Thomas Tratz who owns a KC Compact. Thomas Tratz runs a great website for QuickBASIC. He has given me many of the original manuals, original software, and I bought a real KC Compact from his cousin! A big thankyou to Thomas and his cousin!
The case of the KC compact is the same as the Robotron BIC A5105, but has different hardware inside. The KC Compact I have does not have a information sticker on the underside, but information for the A5105!
Many of the IC's inside are Russian and clones of other IC's. (The U880 is a clone of the Zilog Z80, and the U82536 is a clone of the Zilog Z8536).
I know of only a few people who have a real KC Compact (Andreas Kruger, Thomas Tratz, Frank Salmon of Oldbits computer collection and myself), if there are others please contact me and I will make a list of KC Compact owners, and you will be members of an exclusive club! :)
This document will describe the hardware and software differences (that are known) between this system and the Amstrad CPC.
