very cool... keep us informed as i'm very interested in this. as an aside. I
have a ton of little HD's from apple mac lappys. various sizes from 80meg to
250 meg which are SCSI. does any1 know if i can get a scsi interface and use
them on the beeb and how I would go about doing it?
as for cdrom;'s they should "theoretically" work out the box as they just
look like a read only hard drive. I would assume u just need to handle
writes in that sense.
now what WOULD be cool is if someone could add suppport for something
likeext2 (being OSS) into the beeb.. then you could read/write things onto a
linux box and put them straight into the beeb w/o a prob.
I would have suggested FAT as that's easier and smaller to code (iirc) but
the prob is we'd prolly get dumped on by M$.
regards
charles
