Are you keeping up with Commodore?

Apparently I am, now.
These aren't my usual collectables, but I still find them fun and for the right price I'm keen because they were quite a big part of home computing history and there is an massive software library for them.
So originally (as per previous thread) I got a C64C in a bundle with other machines. After much playing around I got it to start but the keyboard was broken. I organized a replacement through here and WelshWizard kindly sent one down. But then it wouldn't start any more! I had a hot RAM chip - so I replaced both memory modules with 'new' replacements. Still no life.
So I hop on trademe, find another for $20, it arrives and black screen still.
So I hop back on trademe, and find a disk drive and working C64C with damaged keyboard for cheap. This arrived with a proper 5 pin video cable, serial cable, drive, etc. I connected it up using the same cable setup I originally used on the older machines, black screen.
Then I used the proper 5 pin cable, and it appears this was the problem.
C64C #1 - faulty
C64C #2 - works perfectly although quite yellow (older C64C - labelled "C64")
C64C #3 - needed replacement keyboard, but works perfectly now and is still white in colour (newer C64C, labelled C64C)
VIC20 - powered up first go, no problems
C64C disk drive - formatted, loaded, saved - perfect
C64 breadbin style drive - makes all the right noises but had trouble reading the disk (alignment/clean needed)
Datasettes - they work but no suprise there - loaded up the Introduction to Basic quiz off a VIC20 tape
Since my 7 pin cable used to work on C64C's, I can only imagine that it's become damaged at some point.
I snapped pictures on my phone last night but somebody reorganized the office and my cable has gone missing. Will upload soon.
I've been instructed that this weekend I must build a PC<-->1541 cable so we can play games on them.
