Running a bit off-topic here, but I'm giving it a shot anyway.
A colleague came up to me and asked if I wanted "something that's twice as good as a C64" - for free. Obviously, I accepted the offer without hesitation. Turned out it was a C128 in original box with cassette player, PSU, games, joysticks - the lot. Yay!
Now, I don't know much about C128's, but I noticed the RGBI connector on the back.
Is this similar to the RGBI on the Amiga?
If so, are there any scandoublers avaiable for the C128?
