this analog board looks different from the other ones I have delt with, is it rare or different? Should I leave the macsnap board? Is this rare? I also noticed the RAM looks different, I attached pictures of it. Is this hard to find? Thanks | Posted by: joshc on 2022-09-16 16:14:36
Different revisions of analog boards exist and some have components that look different to each other. So nothing too out of the ordinary there. It looks like yours has a smaller flyback which indicates an earlier analog board, and those are definitely the original capacitors.
The MacSnap board itself is valuable, a lot of machines won’t have it and it will make yours much more usable.
Your RAM looks like RAM, what am I missing there? | Posted by: MacTopus29 on 2022-09-16 17:18:41

I also wanted to say that the RIFA cap blew up and I was wondering if it's worth keeping the analog board and soldering a new RIFA cap on or just buying a new one from Ebay. unfortunately, on the MacSnap board one of the pins are broken, is there any way to fix it?
Yes, the RAM looks like RAM, lol. I meant to say that the RAM was socketed unlike other RAM's I've seen. The RAM's I've seen are soldered on and have the apple logo on them. My bad, the Macsnap board is supposed to be missing one pin from the beginning. | Posted by: Juror22 on 2022-09-16 19:44:27
wondering if it's worth keeping the analog board and soldering a new RIFA cap on or just buying a new one from Ebay There is no guarantee that the one you get on eBay will be working - most likely you would have to repair it and/or replace parts there too. If I had to make the choice between a used $65 analog board vs. a 70 cent RIFA cap to fix the one I have, I know what I would choose, but your skills may point you another direction.
There were a lot of board modifications/upgrades going on when those machines were out, so the socketed RAM appears to be from the period of the machine, or it could have been added after. | Posted by: joshc on 2022-09-16 22:42:41
I also wanted to say that the RIFA cap blew up and I was wondering if it's worth keeping the analog board and soldering a new RIFA cap on or just buying a new one from Ebay Replacing the RIFAs is something that has to be done with any analog board that hasn't been recapped/refurbished yet, so you may as well just do that on the board you have. The board you have looks period accurate for your machine.
unfortunately, on the MacSnap board one of the pins are broken, is there any way to fix it? Post some photos, can't tell without seeing it. | Posted by: unity on 2022-09-17 19:42:34
That is an early 128k analog board. Probably week 24 or earlier. Its dated on the board under the plastic cover. But looks pretty standard as other said. | | 1 |
