Hi there!

A friend of mine, and I are working on a serious project on the Amiga.
It is already 12000 lines source. But then the hardware will come through.
So we have some questions, that I hope someone could send me some answers!
Doesnt matter if you just know something about it, or could reference me
to a place where I could get more information!

1) I would like all information about the OVR (Override) pin on the GARY,
   which are connected too pin 17 on the expansion bus.

2) The new hardware addresses like DFF1DC, and DFF002 where you could check
   if you have the new Agnus chip etc.

3) The memory clock bits! We know how to set the time and date but not all
   bits. I mean the expansion clock at $DC0000.

4) Where could I get information about the FFS on the disks? How the blocks
   are structured etc. We know the SFS and made some really fasts routines,
   to load and save amigados files, but whant to know the FFS too.

5) The Dos hunks. Like overlays and so, the codes etc. like $03F3, $03E2.

6) How could we access a regular SCSI harddisk without reffering to DH0:


We program in pure Assembly Code, and really need some information, especially
about the hardware. We don't like smelly computers...

Please help us. My friend doesn't have access to this net so send me the mail.

Ron Birk and Per Hakan Sundell.
