The Radio Shack TRS 80 Model 1 26-1008 to my knowledge never appeared in the Radio Shack catalog and was never officially sold in stores. Obviously a few were made, but how many I do not know. Click image for larger view.
Given the serial number, at least 38 and probably a hundred or so 26-1008 model number Model 1's were produced. Click image for larger view.
Other than the (I have been told) MOS chips on the inside, externally this system looks like any later TRS 80 Model 1. I am guessing this is a first run or pre-mass-production model, produced in the Texas location. From what I read, the Model 1 was cancelled because it failed the new FCC RF interference regulations (1980-1). Click image for larger view.
Pictured is a quick BASIC test just to verify the function of the computer system. For the record, the stock 26-1008 was a 16K Level II machine. Click image for larger view.

This unit has never been opened, so I have not checked the motherboard to confirm it has MOS chips like the other 26-1008 I read about. If I open the case there is a sticker that I'd have to rip, and then it was void the warranty. :-)
