Yow! I saw this on another forum. It's a C128 modernized and redone to fit in a slim-line C64 case. The webpage is at

www.the128rm.com/index.php?id=home

snd the German discussion thread is at

www.forum64.de/index.php?thread/81460-the128rm-the-128-remastered/&postI...

I used translate.google.com in order to translate the first post there --

"Hello everybody,

For some time I have been working on a C128 version, which fits in the C64 case (slim case). I have some modifications built in like: VIC / VDC output switcher, Control port switch, 8 bit color ram, Accepts 6-36VDC input voltage, Dual SID, etc.

Here are some pictures of the project (still in the prototype phase):

Looks like I'll be using a lot of Google Translate, :)
