"My" FORTH was done in 6502 assembler, and used for a water company records and billing system which included interfaces for the company to get the local water flow rates! The meters reported with synthetic voices. Back then BT owned the phone system and were very resistant to letting us pass data from the flow meters to the head office: was it voice or was it data? We argued over that for weeks.
