Hi: I happened to see your posting regarding a search for old Radio Shack Modules. I am just curious if you ever came across the manual for the 20 in 1 Electronics Set (28-245). I happen to have the kit but lost the manual. I have a young son that took an interest in electronics and would love to show him what I had when I was his age. Electronic copy would be fine. Any help would be appreciated. Thanks Louis Rosati
