Owner Registry
Production figures for the TX81Z were never widely published, so there’s no official record of how many were built — or how many survive. This registry is a community census: every owner who logs their unit makes it the closest thing there is to a real count.
Serial number, condition, and configuration are aggregated anonymously into the census.
