I've purchased a second complete Total Shop set-up and based on some of the features and the date of the invoice I suspect it is build around 1983, but since I can't tell for use it has set me to wondering if it would be possible to begin to build something of a registry. I'll continue to research as I can but for now I'll just say if you have a Total Shop tool, how about leaving a comment with your serial number and if you happen to know anything about it's history please share that too.
