Got mine too. Arrived just today. Fitting Xmas present
Tested it and I must say its a fine piece of hardware. Rather impressive to see tech like this on an ancient system like the colecovision.
Just wanted to give Steve my respects here. This cart is quite an accomplishment.
But on a side note: isn't this SD Cart a limited edition? And as such shouldn't it have a running number/serial/something? Mine doesn't have anything like that.
