Geez.. I suppose now I have to register mine. AWESOME score though! I wonder how old mine was. I posted pics of it on January 24, 2010 For it's birthday. That and the fact that mine works now is really nice.
Congrats on yours!!!

Does yours have the 800k floppy drive upgrade too like mine since it was a 512k upgrade? I also love the blue bag!

No drive upgrade. The 800k floppy upgrade was separate from the RAM upgrade. Specifically, it replaced the motherboard not with a 512K upgrade, but with a 512Ke upgrade.

You can tell when yours was built by the serial number. The letter(s) at the start tell you where it was built, then comes one letter for the year, then two numbers for the week of the year, then three characters for the individual serial number during that week. Finally is the model number

So mine is F352035M0001. Split up: F 3 52 035 M0001. F = Built in Fremont, CA. 3 = 1983. 52 = Week 52 (the last week of 1983.) 035 = 107th built (it's in base-36, aka this group may contain numbers 0-9 and letters A-Z.) M0001 = model M0001.
