bugs fixed

  • AltirraOS: Implemented XL/XE NOCLIK variable.
  • Cartridge: Fixed MegaCart 512K (3) banking disable behavior to only use bit 7.
  • Debugger: .diskreadsec now always uses the virtual sector length for consistency with .diskwritesec.
  • Disk: Fixed hang when loading ATX images with extra data pointing to out-of-range sectors.

authors comment:

  • AltirraOS bumped to 3.29: NOCLIK is now implemented in XL/XE mode.
  • Megacart (3) 512K banking fixed to only use bit 7 for disable.
  • Fixed a crash that could occur if somehow a disk image got persisted in settings with an empty path.
  • The Wine64 on macOS bug workaround has now been enabled by default -- it activates on the x64 build whenever a bad TEB pointer is detected and the program is running under Wine.
  • Debugger: .diskreadsec command now always uses the virtual sector size, for consistency with .diskwritesec.
  • Removed an unnecessary stat call in most file open paths and fixed some cases of poorly buffered disk image I/O.
  • Fixed bug where some portions of the emulator like the Disk Explorer could not write to double-density boot sectors when formatted by a full drive emulator.
  • Fixed bug where XFD image files were always completely rewritten on the first write instead of being incrementally updated.
  • Fixed the FDC to use proper write track limits for 300 and 360 RPM disk drives. Removed a hack that had been put in to make the 1050 work, as it now properly runs the FDC in 8" mode as the real drive does.
  • Fixed an FDC issue preventing the 1050 Duplicator firmware from formatting disks (waiting too long for initial byte write).
  • ATX: Sectors are now properly sorted by ascending position when writing.
  • ATX: Fixed bug where an unmatched extra sector info chunk would cause the parser to hang.
  • ATX: Added experimental support for double density images. The specification for this is not yet finalized, so this is gated in Tools > Advanced Configuration > image.disk.atx.full_sector_support.

  • Devices: Fixed a case where Rapidus could fail to cleanly switch from the 65C816 to the 6502..

authors comment:

  • Fixes an issue with Rapidus emulation where an unclean CPU switch would occur from 65C816 to 6502 mode.
  • 815 emulation now supports writing and formatting. Note that attempting to format a format-protected disk (VRWSafe mode) will end up going through the entire format, as the emulator has no way to know that the 815 is trying to format the disk until it's too late to stop it (though it will block the writes).
  • Fixed an 815 bug with sector corruption across the index mark.
  • Fixed an 815 bug with the drive indicator being left on for drive 2.
  • 815 drive ID configuration now works.

  • Disk: Added full emulation for the Atari 815 disk drive (read only)..

bugs fixed

authors comment:

  • Fixes to effective address computations for non-history based disassemblies.
  • Initial read-only emulation for the Atari 815 disk drive.

For those who don't know, the Atari 815 is an odd duck. It has two drive mechanisms and is the only Atari 8-bit disk drive I know of that has no floppy drive controller chip. Instead, Atari opted to brute force it with a 2MHz 6507 (faster than the computer!), 4K of ROM, three 6532 RIOT chips (mislabeled as PIAs), a MC6852 Synchronous Serial Data Adapter (a.k.a. overgrown shift register), and a data separator made out of miscellaneous logic. It is also the only disk drive that cannot read a single density disk, with its hardware and firmware limited to MFM. It also cannot read enhanced density -- the hardware is capable of doing so, but we'll give the designers a pass for not supporting a format that didn't exist yet. The 815 does support code upload, and a couple of the extra commands are suspiciously similar to ones in the 810 revision E firmware, which implies a relationship between the two. No support for high-speed, sadly, even with the 4K ROM and 2MHz CPU -- and with hardware support for another 2K ROM expansion this drive could have done a lot. As the 815 has no FDC, the firmware itself reads and writes raw MFM data, including scanning for sector headers. The emulator has to synthesize a raw MFM track to support this and without the FDC doesn't know what sectors the firmware is trying to access, so currently the emulation is read-only and only shows track numbers instead of sector numbers. The hardware strips MFM clock bits on read but requires the firmware to encode to MFM and calculate CRC-16s in software. It's surprisingly capable of doing this with the 2MHz CPU and the drive formats with a 16:1 interleave, slightly faster than US Doubler standard interleave. The one sub-par thing I've found is sync -- instead of just waiting for the $4489 pattern to appear, the 815 has to use a two-step process to detect the $44 and then check the $89. This means that it will miss the sync when a pattern like $44489 shows up and makes the drive unusually dependent upon the $00 bytes before the sync. The drive also doesn't report errors the same way as an FDC, although this is hard for me to test as ATX doesn't support double density disks yet and there aren't really any copy protected double density disks anyway.
The 815 seems to be format compatible with other double density drives, including the three boot sector convention -- which is interesting, considering when this drive was made (1980-1981?). It's also the only drive to implement the mysterious Read Spin, Motor On, and Verify Sector commands documented in the Atari Operating System Manual that no other drive implements.
You'll need the 4K firmware to make this work, combining the two 2K ROM images. I've opted for a format where the A107 chip is first and the A106 chip is second, which matches the canonical order in the address space ($0800-17FF). For convenience, it is attached. All copies of the 815 firmware that I have found, including those from Bob Woolley, are the same, with A107 CRC32 32BD3CFD, A106 CRC32 C13657E0, combined CRC32 1527D542. Some dumps come with an extra 6-byte Atari executable header that must be removed.

Altirra 4.00 Beta XIII 10/09/2020

changes

  • nw

features added

  • Debugger: Effective addresses are now shown in history in 65C816 mode.
  • UI: Performance analyzer now supports dark mode.

bugs fixed

  • Disk: Added workaround for 1050 Turbo firmware not detecting density if the drive is powered up with a disk already inserted.
  • PerfAnalyzer: Fixed painting bug with ANTIC DL event channel at some zoom levels and scroll positions.

authors comment:

  • 65C816 execution history now contains effective addresses for indexed and indirect modes. (This doesn't fix the case in the console window yet, which uses current state instead of history state.)
  • Added workaround for 1050 Turbo power-up density detection bug: when a power-up occurs with a disk already in the drive, the emulator toggles Not Ready until the firmware notices the disk.
  • Performance analyzer now supports dark mode.
  • Fixed a redraw issue and potential crash with the ANTIC display list (DL) timeline in traces. This typically manifested as it not drawing at some zoom levels.
  • Improved performance of the video trace timeline by caching the bitmaps and fixing a bug that caused an overly expensive downscaling filter to be used.
  • Added an awful hack to try to work around the problems in Wine64 on macOS: specifying /macwine64hack on the command-line will try to work around the broken GS: selector that only works for gs:[30h] and gs:[58h] offsets and causes newer Visual C++ runtimes to crash, by patching the CRT to go through the TEB->Self pointer instead. If this works then it can be made a bit more automatic.

  • UI: Fixed mouse wheel scrolling when the system wheel scroll setting is set to pages instead of lines.
  • UI: Profile editor no longer allows parenting a profile to itself or its children.
  • UI: Settings load/save code now detects profile loops due to the profile editor bug and forces a reparent to the global profile so settings saving still works.
  • VBXE: Improved GTIA state syncing when toggling VBXE on the fly.
  • XEP80: Scrolling now always removes one physical line, not a logical line as E: does.
  • XEP80: Fixed an occasional issue with indeterminate state after cold reset.

Author's Comment:

  • Percom AT-88 V1.2 ROM added to firmware autodetect list.
  • Fixed a bug with script threads in custom devices where the scheduler would screw up with multiple ready threads.
  • 6809 disassembler no longer prints branch targets >$10000.
  • rawdiskhs.atdevice is now one of the samples.
  • Fixed a bug in the FDC where the force immediate interrupt ($D8) command was not triggering an interrupt when interrupting another command, which was causing the Indus GT firmware to hang on a Read Address command with no disk in the drive.

Indus GT should have still worked if a disk was in the drive on cold reset; LMK if you're still seeing the hang. The drive should also still do the power-up seek regardless. I have seen cases where the Indus GT might not init quickly enough if you have an OS that boots too fast, so if it's just missing the boot then increase the power-up delay.
