hehe.

Well, the chip's now here. It'll be a simple 2 minute job to swap them over as it's now socketed and I've not screwed the top on the C64.

Tell them (in true shareholder take over bid fashion) that they have been outvoted (i.e. by me and @rubber_jonnie) so to let you go home right now.

No changes. It's just the same.

I'm leaning towards the conclusion that it's a "feature" of this particular motherboard revision.
