[Coco] Unknown Coco 2 - Socketed

[Kip Koon]

Hi Guys!

I hope everyone is doing well.  

I have a Coco 2 with a "Radio Shack TRS-80 64K Color Computer 2" label
centered on top and absolutely no label on the bottom of the unit.  None!

All the ICs on the rectangular motherboard are socketed.  Since my phone is
out of juice just now I can't put any pictures in my dropbox to show you
guys.

How many versions of the above mentioned 64K Coco 2 had a rectangular
motherboard with all ICs socketed?  I'd like to id this version of the Coco
2 if possible.
