What's New

  • [Change #1392, #1423] Add a 64-bit version of AppleWin to the distro: AppleWin-x64.exe (beta).
  • [Change #451] Debugger: Support address prefixes for breakpoints and Mini mem dump window:
    • bp or bpm[r|w] [s/][/][l/][rom/]
    • Similar for m commands.
    • Additionally inspect Mockingboard state: m s/[a|b]|ay[a|b]>
    • Extend the UI to show specifics of memory bank number & LC 4K bank 1 or 2.
    • Extend the 'bpl' command (Breakpoint List) to include the full address prefix.
    • See AppleWin.chm help doc, Debugger: Breakpoints & Memory sections.
    • NB. divide operator changed to '//'
  • [Change #1416] Mockingboard and Phasor cards now default to SSI263AP (instead of older SSI263P).
    • mb-audit 1.57 (and earlier) will now fail the Phasor/SSI263 reset test: "43:F1:00, Expected:02 Actual:00".
    • Restore the old AppleWin behaviour with, eg. '-s4 socket1=ssi263p' for the SSI263 at $C440.
    • NB. mb-audit 1.58 supports both the SSI263P & SSI263AP for this Phasor/SSI263 reset test.
    • Add command line to add/remove SC01: -sN .|sc01>
  • [Change #1421] Debugger: reduce start-up console output, and add new 'log' command.
  • [Bug #1428] Fix issue when changing Apple II model where aux slot became empty (regression at 1.30.21).
  • [Bug #1414] RamWorks III: Power-cycle now resets to bank 0.
  • [Bug #1412] SSI263: Chip power-down not silencing continuous phoneme (regression at 1.30.21).
  • [Bug #1407] Mute any sound when right-context (pop-up) menus are shown.

Note: This is the last planned version to support Windows XP.

  • [Change #1363] Right-click Disk Drive buttons QoL features to manage new disk images.
  • Support creation of new DOS/ProDOS blank or formatted disk (including default ProDOS apps).
  • [PR #1364] Document the new UI workflows.
  • [PR #1375] Document the disk image size magic numbers.
  • [Change #1365] Update disk images included with AppleWin distro.
  • [Change #438] Remove MASTER.DSK and add BLANK.DSK (created using the newly added DOS 3.3 System Master disk).
  • Add 'DOS 3.3 System Master - 680-0210-A.dsk'.
  • Add 'ProDOS_2_4_3.po'.
  • [Change #478] Support up to 16MiB in RamWorks III card (-r 256), and default to 1MiB (eg. -aux rw3, without -r switch)
  • [Change #1397] Debugger: Monitor's memcpy: Warn and abort when the source's end address is below the source's start address.
  • [Change #1384] Debugger: Support viewing pseudo-HGR pages at all multiple-of-8K physical start addresses within the 64K main memory.
  • [Change #1341] Support Apple //e with empty aux slot, or with a 1KiB 80-column card.
  • Includes accurately supporting the video modes, eg. aux=empty and enabling 80COL, then floating bus is fetched for aux memory.
  • Currently only available via the command line: -aux .|std80|ext80|rw3>
  • NB. For -aux empty, -aux std80 and -alt-cpu-emu this uses a different CPU emulation code path, where full-speed runs 25% slower.
  • [Change #1403] Help window now owned by the desktop (instead of AppleWin window).
  • Change: Improve logging: for -fs-width/height=x: for each display resolution, after the WxH also output the aspect ratio.
