- IDE driver (note the ubee512 emulator ide appears to be very busted as
of 5.8.0)
- If we have wd1002-5 and fd wtf do we put IDE in major/minors ?
+- Video support (colour, attributes) DONE
+- Map video at 0x8000 DONE
+- Clear attribute ram if present DONE
+- Move common up DONE
+- Do buffer over discard change DONE
+- Check we have video latches/map right everywhere DONE
+- Init vtattr_cap and the video variables correctly DONE (I think)
+- Check if scrolling in hw is doable or not in 80x25 NO
+- Support 'map video into my process at 0x8000 hack' DONE
+- Non premium video COLOUR DONE
+- Non premium video setup COLOUR DONE
+- Support RAM font setting DONE
+- Figure out how I broke the 6545 cursor DONE
In Progress
+- Debugging floppy driver - we seem to have broken it
+- Swap
+- Graphics not just vt interfaces
+- RAM based fonts
+- Premium models hang somewhere as if there's a memory banking bug
+ (seems to be a size related Heisenbug)
To Do:
- Floppy - media detect/sectors per track etc/ hard skew
- Fix reboot/panic logic
- Keyboard repeat
-- Graphics not just vt interfaces
-- Premium models hang somewhere as if there's a memory banking bug
+- Speed up RTC timer a bit for lpen based boxes so we don't miss keys
Longer Term
-- RAM based fonts (load the ROM one into RAM
- customised for bold/italic ?)
- Do delayed video output via a buffer off vblank event for non premium
- Proper support for Z80 PIO interfaces
- Z8530 SCC
we'll need graphics mode support for other modes
-
-Currently in progress
