Edit: here is a really nice DFS guide: http://bbc.nvg.org/doc/DFS.rtf
So do I need to load specific drivers If I plug in another disc driver? I have a 40 track drive but I just purchased an 80 from Ebay. Will I have to load some software when i get it?

Also do I need to do anything special to get BBC B progs to run on a Master? I seem to hear reference to turning off the 2nd processor but no idea what to do.

No, you won't need any additional drivers or anything. Some FDDs even have a track switcher so you can interchange when required.

As for BBC B games, have a go and see if they work first, else you can get your hands on a B emulator which ups the compatibility a bit. I remember we had a couple of bits of educational software that came with one included. I rarely had to resort to using it though, as normally all you'll get are some minor graphical anomalies. However, unfortunately, there are some games that won't work properly at all, EVEN using an emulator, but I think I only ever encountered about 2 (baff) games that this happened to me with.

I just bought a copy of Elite off Ebay. Booted it up only to get a message that its only for a BBC Microcomputer. Bit annoyed as I was under the impression that Elite would work. The drive I have is only a 40 track though. In fact none of the discs I have seem to do anything. Every time I use *CAT I get a Disc fault 18 error.

I think that means you need to get an 80 track drive. I've always had 40/80 switchable drives for maximum compatibility. :)

One thing you might have to bear in mind is that the BBC Micro supported two different disk operating systems DFS and the later ADFS which supports directories, longer filenames and higher capacities. The Master 128 has both in ROM, but defaults to DFS. If you can't read a disk, try typing in *ADFS and see whether you have any luck.

Will take a couple of days to arrive but hopefully it will be the answer to all my prayers.

Don't you need the systems disk for the BBC i order to formal disks.

I thought the format command was stored on disk and not built in?

It's been a while sinse I've used my BBC so I may be talking rubbish! :roll:

Depends on what ROM version is installed, I think.

That BBC will be cracking to learn a bit of dead simple basic games programming.
I made a terrible space invader type thing years ago on one at school.
along with 100's of choose your own adventure games :P

I loved Citadel on the Beeb and Chuckie Egg most

I think the Disc Filing System (A-DFS) is an extra add-on supplied on an EPROM that fits into the little rectangular hole to the right of your keyboard, I may be wrong!

I think the 'standard' imbedded disk operating commands (from the BASIC ROM) don’t have any ROM based format facility.

Maybe the BBC-Master has the DFS built in by default.

I think you could also get a CPM operating systems chip for the BBC, I know the Z80 co-processor was available.

I don't think that ADFS was ever available for the Beeb. There were utility discs for various DFS. Most of the time you had to buy a disc tool kit in ROM and fit that to the Beeb. Later DFS versions did have the commands built in. On the Master the commands should be built in but my version of ADFS on the Elk has a utility disc. :)
