Y2K updates for OS-9 level I (184,347 bytes)
Updates to fix year 2000 in OS-9 Level 1 for Dragon 64 computer. This disk contains changes to the utilities Date, Dir, Free, Login, Setime, Basic09 and Runb. It was the intention to provide the same user experience as in 1980. Therefore most utilities will still display a two-digit year except 'date', which shows the full four digits. Setime in particular still expects a two-digit year and will then adjust to the twenty-first century unless no date is entered. The sources are provided for your own assembly.
