Hi,

I have recently acquired a vintage Mac II. However it needs a few upgrades. It still has the hochsprung MMU which I want to swap for the Motorola 68851. I have 1 on order so that is covered. What I have trouble finding is the SWIM chip upgrade or one that even looks the same. Anybody know If any of these are available and where to get them? Apple upgrades kits I expect are no longer available so 2nd hand recovery would be typical. Any info would be helpful.
