Good book or guide on how FS ROMs work

Evening everyone! Does anyone have any recommendations for good books or well-commented assembly examples that demonstrates how filing system ROMs communicate with the OS? What the OS expects of a well-behaved FS? It's mostly as an exercise in self-education but also for my homemade-beeb project. Th...

Hi I may be coming up to Alrewas to visit the National Memorial Arboretum on Wednesday so if nobody nearer has already picked them up and if I do come up (from Hampshire so not a decision to be taken lightly), I'd love to take them. I used to have all the Disc User magazines and a large selection o...

Hey,
In that lot, do you have the A&B spring supplement? or some Beebug sales pamphlets that came with the magazine from 1982 or 1983?? :D

Re: For free: "Master" badged monitor, Burton on Trent, DE15

HI everyone!

Thanks to everyone who replied, and sorry I haven't been more responsive. I didn't want to say "this has now gone" until it actually went, and the recent snow in the UK slowed things down a lot.

The monitor is now on its way to its new home.

All the best,

Re: Playing with the SAA5050

Hi Robert, I think you are possibly storing your teletext page in the ROM in the wrong way. From the schematic, it looks like each 40 character line needs to be aligned to a 64-byte boundary in the ROM. Whereas I'm guessing you have just taken a standard test page and stored it in the first 1000 by...
