- by Philip Pemberton <philpem@philpem.me.uk> [Fri, 12 Apr 2013 16:26:25 +0100] rev 144
- Don't set PS1 if there is a level-7 interrupt or bus error
PS1 should only be set if the page was originally present (PS1 or PS0 set). If
PS0 and PS1 are clear (page not present) then do NOT set PS1.
Once again the TRM is blatantly and spectacularly wrong...

- Fix read-after-write logic
In some cases (notably reading from a page after having written to it), the
mapper may change the pagestate from "accessed and written" ("dirty"; PS0,PS1)
to "accessed but not written" (clean; PS1,!PS0). This should never, ever, EVER
happen. Once a page is dirty, it remains so until the 68k clears the DIRTY
bit.
Once again, this wonderful bit of logic was missing from the TRM.

- [wd2010,main] WD2010 disc geometry fixes
I believe I have fixed the geometry problem with FreeBee. The geometry was set
to 17 sectors per track instead of 16, which obviously throws off addressing.
I changed it to use 16 sectors per track. However, s4diag tries to format
sector 17, so I changed the WD2010 emulation to accept any address when
formatting (since the format command doesn't actually do anything, it doesn't
matter). It is now possible to format the hard disk, initialize the file
system, and mount it. However, cpio still fails to copy the system to the hard
disk.
