MANUAL FOR OSWDTCT (BBC BASIC)

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
hardware software to allow the 'Doomsday' ROM to be used.
The 'Doomsday' ROM extends the date range of 8 bit Acorns from 1900-1999 to the
year 1900-2299, and also adds several useful *commands.
The manual and software is (C)1997 SPROW

INSTRUCTIONS-
At the BASIC prompt, type CHAIN"OSWDTCT"

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 this machine.
