[wd2010,main] WD2010 disc geometry fixes

• Wed, 13 Mar 2013 00:43:25 +0000
• by Philip Pemberton <philpem@philpem.me.uk> [Wed, 13 Mar 2013 00:43:25 +0000] rev 134
• [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.

[memory] Emulate main memory read wrap-around

• Fri, 18 Jan 2013 17:18:50 +0000
• by Philip Pemberton <philpem@philpem.me.uk> [Fri, 18 Jan 2013 17:18:50 +0000] rev 129
• [memory] Emulate main memory read wrap-around
  
  3B1s with 512K or 1MB of base memory have a decoding quirk which causes reads
  to 'wrap around'. That is to say, on a 512K machine, reading from addresses 0,
  512K, 1024K or 1536K will address the same RAM byte. On a 1MB machine,
  addresses 0 and 1024K address the same RAM byte.
  
  Emulating this incorrectly causes P4TEST to report an incorrect amount of
  available base RAM.

fix default HDD sectors-per-track

• Wed, 16 Jan 2013 00:41:51 +0000
• by Philip Pemberton <philpem@philpem.me.uk> [Wed, 16 Jan 2013 00:41:51 +0000] rev 127
• fix default HDD sectors-per-track
  
  The 64MB Micropolis drive we're trying to emulate in FreeBee has 17 sectors
  per track. Fix this in main.c to avoid tripping the sector range checks.
