Missing capacitors on Umax Gemini secondary CPU card

[Branchus]

Hello all,

I have a Umax Gemini secondary CPU card (604e 250MHz) but it's been through the wars and lost a few surface mount electrolytic caps. If anyone has one of these and can tell me what sort of caps I'm missing, or a picture of one that I can use as a guide, it would be greatly appreciated!

I haven't had it under the microscope yet, but at a glance, it looks like the missing resistors are meant to be that way. I think the only components that were deliberately removed are the surface mount electrolytics.

I'll take a wild guess and say it's probably 47uf 16v or 100uf 16v. The Apple 604e 200Mhz card (630-2508-A) I got seems to be using 47uf 16v on the caps I can see without taking off the heatsink.

This has the same layout as mine:

I'll keep on looking to see if I can find anything else.

Here is my Umax primary 604e 225MHz. These cards need to team up in a in a Supermac S900, if possible....... Would definitely make a great video!
