Default Amiga 4000 Desktop Motherboard (Rev C)
What is the story with A4000 Rev.C motherboard?

There are very few information about it on the Net. Most sites say that it is rare. Also, It has built-in 030 CPU and "Chip Ram surface mounted onto the motherboard".

It's probably a cost reduced version.

Rev D is the better-known cost-reduced version, so C must have been an earlier version along those same lines. C does appear to be rather uncommon, but I don't think there's anything particularly special or desirable about it to differentiate it from Rev D. If it has a coin battery like Rev D instead of a barrel battery, that would be neat.

Just curious would anybody know what the price difference was between a rechargeable battery and a coin battery in the late 80's - early 90's.. Because commodore being so cheap I would have thought coin batteries would have been a cheaper option in all big box Amigas?
