This file describes the program OSWDTCT which makes several OS calls to your version of the Operating System, and additional ROMs, to see if you have suitable hard- and software to allow the DOOMSDAY ROM to be used.
The DOOMSDAY ROM extends the date range of 8bit Acorns from 1900-1999 to the year 1800-2199, and also adds several useful *commands.
Instructions
At the BASIC prompt, if not calling from the EUG Utilities Menu, type:
>CHAIN"U.OSWDTCT" <RETURN>
The program will then report back to you which OS calls you have available, which it needs to run. Plus an overall opinion whether DOOMSDAY will function or not in your machine.
