I don't know if that tells you anything, or even what the date code of your original one was. But let me know if any of these are in the ball park. The cases are all in very nice condition, just a bit dusty. The 'No Power' one is the cleanest by far, and still has the protective plastic film on the Cart door and only a few very slight scuff marks on the clear plastic bezel on the right (would polish right out). Even the brushed aluminum buttons are in very good condition. Of course any bottom can be swapped with any top. I got these cheap in a lot of 5 for about $20 each. I opened up one of the non-Chelco ones that also said 'No Power' and it was missing about half of it's Atari chips. So I think I'll check out the Chelco one and see if it has the same problem I would be willing to sell you any one of these for $30 which should cover my cost+shipping to you if it'll help get a bit closer to your childhood system's time period.
I like your keyboard solution It does look some what familiar
My original is 5th week 1984 : 7YJ HA 54348 5 4
The one I picked up on ebay is 49th week of 1983: 7YJ HA 23865 49 3
So all of yours are a bit older, and most likely all REV A1. I still appreciate the offer, though!
Interesting that if the serial numbers are indeed sequential, they churned out almost 7000 units in around 1-2 weeks time - based on the count from my ebay unit to your newest unit. You also have two made the same week - and most likely the same day, since they are within 13 of each other. Keep that pair together! Or maybe I'm the only one who thinks that's cool.
