Disc reader project -- quick status update

Hi guys, Just a quick update regarding the disc reader project. I've added sync-on-MFM-word to the microcode, and the software MFM decoder is working. I got the first valid MFM decode using the "soft-PLL" decoder engine about five minutes ago -- the first 16 bytes of an MS-DOS 5.0 boot sector. I can see all the sector headers, address marks and pad bytes displayed on the screen. "Just a bit" more than the PC disc controller lets you see... :) Now to find a disc with a slightly less ordinary format... perhaps a BBC Micro (Acorn DFS) disc? My target is still an Amiga disk, if I can get my hands on one with known contents. More to come when I've had some sleep... I'll see if I can get some photos of the hardware (and maybe schematics) uploaded in the next couple of days. Cheers, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
