Schematic for the IIe Card?
Posted by: ScutBoy on 2020-06-19 08:10:24
I pulled the IIe card out of my Color Classic since I had the caps for it, and in taking off the caps one practically fell off, taking the pads with it.

The cap is C2 - 220uf 35v.

There are vias there next to where the pads used to be, but I'd like a peek at the schematic to know where the positive side goes in case I need to bodge something up. A quick google didn't turn up any schematic, or at least not one I could find in all the other Apple ][ card schematics that are out there.

TIA

Crisis averted! 🙂

I found I had a cap of the correct value with legs. After some work to get the vias open, I was able to solder in the cap and the IIe card is working like a charm, along with the recapped CC logic board.

I think those are actually 22uF instead of 220uF.

It probably would have worked just fine even without the cap that fell off.

I think both caps are just connected between ground and 5V.

@Bolle - You are correct 22uF, not 220uF. My mistake...
