Sega Genesis / Mega Drive prototype pcbs

[fcgamer | 4,723]

I was looking online at Sega prototypes, and I saw this thread referencing this to be a Sega prototype PCB:

Then I found a few more threads with Sega prototypes with similar PCBs:

http://www.nintendoplayer.com/prototype/pirates-gold/

I guess what I am wondering is was thus type of PCB only used for prototypes, or was it also used elsewhere?

Edit: Also, has anyone ever seen one of these with the code 171-5694, instead of 171-5694-01?
