Found this on ebay not getting any attention, so I put in a bid on it. I think the seller made a mistake with the listing because it wasn't showing up in the usual search for Apple II motherboards.
Don't know what the story is with all the desoldered (or never installed?) sockets. Anyone know where I can get correct replacement sockets?
I'm sure this thing is how it is for a reason, but I only wanted an example of a Rev 07(the long, long term goal is get a representative of each 820-0001-xx part number (I'll skip on the all variations within, unless I stumble on it like I did with the black slot Rev 04).
Interestingly the date code on it is 20-something weeks later than my Rev 04.. is that all the time it took to go through 3 more revisions?
I wonder if this was an Early Production Run Rev-07 board...
I see some Solder in some of the Holes in the D0 and D8 ROMs positions..
Indeed, It definitely looks like it has a story.....
Yeah I agree the story on this one must be interesting. I mean, straightforward parts scavenging -- why go for the sockets? I was thinking maybe somebody trying to do up an Apple I replica (even though these wouldn't be correct), but then why remove the game port? If scavenging for a ravaged Apple II board, why remove them in a linear fashion like that instead of just the random ones you need? The pattern is what makes it interesting.
I think someone was troubleshooting a signal short on the board, or it was partially under water or something that caused a section of sockets to corrode and they started removing and never finished. Notice the rework wiring on the back as well...
Maybe someone was practicing their desoldering skills.
Looks like someone was recycling some sockets. They started at one end and stopped when they had enough for the next few projects. I've known a few people that would have done that. Sometimes they'd pull parts until they got tired or something came up.
