Sounds like the same place. They had a lot of around 35 of them for sale at a Buy It Now Price of $40 and change, including shipping, so I figured, why not? I figured someone will eventually figure out a way to store stuff for this thing (or should I say hope?).
On the opposite end of the spectrum, I only recently realized I had a Tandy Model 102 which I bought in the early 90s at an auction but never knew what it was. I think it was included in a box lot of computers which included a C64. When I looked online to see if there was any info available on it, I found out that some years back there was a pretty dedicated following for it. So instead of being ahead of the game with the CC-40, it looks like I missed the boat on a storage solution for it since the Model 100 website looks to have given up the ghost with no updates in nearly 5 years. I posted a message on the Tandy Computer forum here, but so far, no response.
The Tandy 100/102 was pretty much everything the CC40 wasn't. Hopefully you will get some response. I have a 102 and that reminds me I need to make sure the battery inside isn't leaking! That storage box (REX) is exactly the kind of thing we need for the CC40. I also missed the boat on getting one.
