Hi,
in a few days Macintosh IIvx will arrive. I am looking for informations which capacitors I will need for recap motherboard and PSU but I did not find any informations about this model.
Can I ask You for help with it? Computer should be in a working condition but probably never have been recapped.
Thanks a lot.
Greeting
Daniel

For the logic board, you can use this IIvi guide. The IIvi, IIvx, and Performa 600 use identical boards, it's just that the IIvx's CPU runs at 32MHz on a 16MHz bus and has 32K of L2 cache, the Performa 600 retains the 32MHz CPU and 16MHz bus speed but has no L2 cache, and the IIvi runs at 16MHz for both the CPU and the bus, while also having no L2 cache. The only differences because of that are the presence of cache chips, and the speed of certain clock crystals and the 68030 itself. The capacitors and all other components should be the same.

I don't know about the IIvx specifically, but for a lot of models, there were multiple power supplies used at different times and in different places, so you might have to wait until it arrives to find out precisely what PSU it is you need information for.

You've right. shipment should arrived on friday on monday. Then I will be able to check PSU model.
