Apple II on eBay with 4909 Serial!

[Jesse]

This isn't mine, wish it was and that I could afford it, but here's a
very nice Apple II with Serial 4909:

That mobo is certainly not a match for 4909. No wonder they don't have
a picture of the corner. The pan, keyboard and power supply are fine,
but the motherboard has been replaced.

Did any of the non-Plus II motherboards come without the memory select
jumper blocks? I'm not seeing them on that board.

I couldn't say for sure. Probably not, though.

Looks like they were eliminated with the Rev 4 boards:

My first II Plus came with the 16K blocks, so there was some cross
over. My standard II tech knowledge is a little hazy...

That board looks an awful lot like my 820-0001-07 from 1980.

Rev 4 still has visible 16K blocks, but they're not removable. Pretty
sure that rev 4 was the last revision that had them, but rev 4
definitely had them and rev 7 definitely didn't. There were certainly
both standard II and II plus machines that had rev 4 boards, but my
relatively late red-label A2S1-66838 has a rev 7 (8029) board in it, so
it is possible that rev 7 boards did ship in some standard IIs.

Motherboard in the auction is now pictured, it's rev 7 (as the seller
indicated in an update to the description).
