It's just an Acorn Archimedes BBC was an older computer
Yes and no
First thing you need is an emulator of the system to let you play on a windows system
There are 4 that I know of but it's been too many years since I looked at those to be able to tell what is the best of those
I will list the live ones though

Note read the web sites carefully some of those base emulators do have branch versions done by other groups that may be more up to date
RISC OS ROM will also be needed (think of it as a bios image)
Finally you will need diskette images
Also note that this system can seem complicated to start with because there are several versions of this computer with several components to it that had been upgradable, a bit like standard PC's of today
