Apple Ethernet NB Card Revisions

[sailingdarter]

I was browsing between different vintage parts lists and found that there were 3 different revisions of the Apple Ethernet NB NuBus Ethernet Card.

820-0417-A​

820-0417-B​

820-0417-C​

I was curious, what were the differences between each revision and which revision is the best one to lookout for.

Thanks

Beats me. I've only ever seen a -C. I would assume the latest revision would be the best. It would have the most recent version of A/ROSE. Maybe it has to do with the amount of RAM pre-installed?
