NitrOS-9 V3.1.3

• The asm program now supports 6309 bitfield instructions.
• The prompt command has been added to the standard command set.
• os9gen now supports the -t= option which allows one to specify an alternate boot track file.
• Two new directories have been added: BOOTLISTS and BOOTSCRIPTS. The former contains bootlist files for building boot disks, while the latter contains scripts to build boot disks.
• There are now two booters for booting from a WD1773-based floppy controller: boot_1773_6ms and boot_1773_30ms for 6 and 30 millisecond step rates.
• The help utility has been enhanced to show help subjects if forked without any command line parameters.

Level 1 Only:

• Clock modules for Eliminator, Disto 2-N-1, Disto 4-N-1, Harris, and SmartWatch have been added (these are all UNTESTED.) Also, the clock_bb clock module has been renamed to clock_bnb, and clock.60hz and clock.50hz have been renamed to clock_soft and clock_soft_50hz.

Level 2 Only:

• The M1 device descriptor now references the SACIA driver.

NitrOS-9 V3.1.2

• A bug in the help utility has been fixed.
• The MODULES directory structure has been enhanced to include multiple subdirectories for better module organization.
• Booter modules for Burke & Burke, Disto RAMPak, Eliminator and IDE-LBA have been added.
• The BOOTLISTS/ directory has been added on the Modules disk, and contains bootlist files for various configurations.
• The cputype command has been optimized for size.
• Minor help file updates have been made.

Level 2 Only:

• Drivers and descriptors for Tandy's Hard Disk Interface have been added to the MODULES directory.
• Slight performance modifications were made to RBF and SCF.
• More commands have been added to the merged utilpak1 file.

NitrOS-9 V3.1.1

• SYS/helpmsg expanded to include new commands.
• ident now correctly reports modules with a language byte of Obj6309.
• The LogBook file in the SYS directory has been removed.
• A bug in the cputype command that caused crashing on a 6809 system has been fixed.

Level 2 Only:

• rbf.mn has been back-ported from NitrOS-9 in order to unify the code base and bring non-6309 specific features to OS-9 Level Two.
• A bug in IOMan which affected any driver wanting to access the port address of its hardware via its path descriptor has been fixed.
• The montype command had a bug-fix and now shows the current monitor type if no parameters are given. Also, the montype.hp file has been updated.

V3.1.0

• New common version among all releases of OS-9 for the CoCo
• Many commands have been updated and optimized:
  • For size reasons, command help information is no longer embedded in the utilities, but is instead available through the helpmsg file in /DD/SYS
  • date, dir, mdir, procs and verify now require a dash (-) before options
  • format now has a cluster option and now shows the correct number of good sectors on large sector devices
  • Numerous commands have been optimized for size
  • cputype, ded, devs, disasm, dmode and irqs have been added to the CMDS directory
  • cmp, error, help and touch have been rewritten in assembly for size
  • copy has been enhanced to include OS-9/68K-like features

Level 2 Only:

• VDGInt has been back-ported to OS-9 Level Two from NitrOS-9. The vdgint.io module contains both CoCo 1/2 AND CoCo 3 graphics code.
  The vdgint_small.io module only contains CoCo 3 graphics code.
• CC3Go has been moved back into the root directory from the CMDS directory. This keeps ROM-based users and those who want cc3go in their boot file from having to change the init module, which referenced CMDS/cc3go.
• CC3Go once again references /H0 and /H0/CMDS as paths that it tries to chd/chx to upon startup. This allows for those with floppy boots who want to point /DD at their floppy to continue to do so. Also, if the forking of shell startup fails due to lack of a shell file, then CC3Go will now try to fork AutoEx instead of jumping to the crash routine.
• Several bugs that crept into IOMan during the last release have been fixed.

V2.1.0 'Phoenix'

V2.1.0 'Phoenix' Release (11/04/2002):

• Defs files now have properly terminated lines and pag is now emitted
  as a comment.
• Asm now assembles 6309 op-codes

Level 1 Only:

• SYS/password now references /DD instead of /D0

Level 2 Only:

• SCF, Rammer and PipeMan are now made from the NitrOS-9 version source base, bringing in new improvements and features from that platform.
• Clock and Clock2 are now unified once again and are built from the same source base as the clocks from NitrOS-9.
• The printer driver is now for the CoCo 3 serial port. In the previous release, it was mistakenly made for the Disto parallel port.
• Window descriptors now have proper initialization count.
• The debug program is now part of the CMDS package.
• With the inclusion of NitrOS-9's SCF, a bug which crashed the system when typing Ctrl+E or Ctrl+C while using Shell+ has been fixed.
