VGA on a Tandy 1000 wasn't all that unusual. Most if not all of the earlier Tandy 1000 models that had ISA slots could take a VGA card in them. The hardware worked fine (it's just memory bus accesses under 1mb and I/O port instructions), it just depended on software support to do anything with it. Tandy's magazine PCM often listed and rated add-in VGA cards. I remember reading of a later version of DeskMate that supported VGA resolution.
Most Tandys with 8-bit ISA slots could not take a VGA card because the internal graphics chip could not be disabled. It was only the later series where that became an option.
