I can't make out the code on your picture either... But it begins with 02 which surely indicates a memory chip failure.

The Mac 512 (website) lists all different kinds of sad mac error codes. 

I think this one displays 02 8400 but I don't know what it means, never seen that one before. I believe it doesn't exist. As you said, it's pretty unreadable.

I'd say bad RAM chip somewhere on that board though.

I have a chance to buy 512K, but it displays 0066FFEE error I cant really decode it. Looks like 3 sad Macs at once!

Charlie, that's a properly screwed up sad mac you got there.

Surely the RAM's bad on this one. But something else might be as well.

It really depends on how much it costs... and how good you are at diagnosing logic boards.

 
BoldEagle: this guy wants 120 EUR, which is seems too much for me, esp. when you consider there's no mouse, nor any keyboard included. 

 
lol I'm not bold.  :p  I really need to think up a new name though ;)  I'm tired of this one, it's been too long.

But yeah it surely is expensive for a non working 512k. You could get one of those in working condition for that price. I don't know where exactly you are located but check your local classifieds. I got really cheap deals on leboncoin (french alternative to Craigslist).

ebay kleineizeigen or subito are good sites too.
