Colecovision Motherboard with Sample Sticker

[TheGato]

Hi,

Just recently picked up my second Colecovision because it came with a ton of games and controllers I needed. 

The powerswitch was very dirty so I took it apart to clean it up and make sure the caps looked good.

At the top right of the motherboard is a handwritten sticker that says sample.

The board is the same revision as my other Coleco the H2 board and it has the same layout with some different chip manfucters. 

I've attached pictures of the two boards. 

Just curious if anyone has seen this before or has any info regarding it. 

 

Thanks,

TheGato
