Upgrades for a Mac II
Posted by: jayco242 on 2014-02-02 08:41:19
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.

to get superdrive support from what i have been told by others on this forum, is a 2 part thing.

rom + swim chip.

if you need to me to solder on a rom simm, so you can use a IIx - IIfx - se/30 rom I can do that for you.. for a charge.. i just did it to mine, i am running a SE/30 stock rom in my Mac II.

Its pretty cool.

Hehe,

thanks for the offer. But I am on a different continent so costs would be prohibitive! I am bidding on a Mac IIx on ebay hopefully that will provide all the spares I need. Good / rare Mac stuff is hard to come by in the UK.
