The only reason I would think to do this is if either that person has no soldering experience and/or wants to keep the board historically accurate but still be able to use it. As for that 64k RAM card, do those chips really work with my system? I'd be forever grateful for the help if they do!

Interesting question: if piggybacking really does work, why don't those will little soldering skill simply attach a ram chip on top of the broken one?

Wouldn't it be a lot cheaper to just replace the faulty RAM?

Are those piggybackable with my soldered 4265s?

Haha no worries, I'm probably wrong. Here is a picture of the RAM on the cards.

So are you saying I can piggyback one of my 6342s on one of the 4264s?

I think I might try piggybacking a 4265 once I can get my hands on one. Can a 4165 replace a 4265?

It looks like my RAM chips are 4264, while my RAMWORKS card has all 6342s.

That sounds like a really cool idea! I have an Applied Engineering RAMWORKS III that came with the computer, it's all socketed so could I pull a chip from there to test with? Also, how exactly do you "piggy back?"

What would really help at this point I guess is to find out which RAM chip (f6-f13 I think) the "RAM 00000001" error is referring to.

I've thoroughly looked at all the RAM chips and even cleaned them a little with some alcohol and scrubbing. It doesn't seem like any of them are suspect cosmetically. And yeah, they are all soldered...

I've pulled all cards and it still says the exact same thing every time.

Hi there! I was wondering if anyone could help me with this particularly pesky problem of mine: So I just recently got an Apple //e off of eBay and was super excited as it came with loads of software and stuff. After cosmetically cleaning it I decided to test and see if the Duodisk it came with...
