I can't find any solid stats, but it does seem like most of the sales were US and Canada. And probably a fair amount of those sales after they priced it below cost during their death throes. I believe it was under $50 at the end, which was crazy cheap at the time.
It was our family's first computer in the UK -- pretty sure my Dad picked it up very cheap when the local department store were getting rid of the last of their stock after TI killed the machine. The lack of commercial games for it compared to the Spectrum etc meant I spent more time typing in BASIC listings, which was my first introduction to computer programming...
