Change Log

*** 0.0.4 ***

• A/UX 3.0.1 and 3.1.0 boot now!
• Now with basic support for Windows/Linux via SDL2
• Supports “thousands” and “millions” of colors
• Lots of little bug fixes:
• A few more implemented FPU instructions
• The video card driver is implemented more fully
• SCSI is more stable under heavy I/O

*** 0.0.3 ***

• Shoebill can now restart and shutdown without crashing (usually)
• PRAM now works and actually persists (in shoebill’s preferences plist)
• The real time clock now works a little bit and reports an approximately correct date to A/UX. I’ll get around to allowing the date to be modified and to allow that modification to persist across restarts.
• When the A/UX scheduler is idling, shoebill will now idle. Specifically, the CPU thread will now sleep when the CPU hits a stop instruction.
• Full screen is now supported
• The VIA timers are a little bit closer to working, although the Macintosh Time Manager is still completely broken.
