/***************************************************************************
DPB-7001 (c) 1981 Quantel
Known issues/possible improvements:
- Disk Sequencer Card is currently implemented via HLE.
- Tablet is currently implemented via HLE.
- Blanking PAL is currently disabled, which results in on-screen
garbage when scrolling.
- Size Card and Filter Card functionality is not yet implemented.
- Video input functionality is not yet implemented.
- There are numerous Brush Processor Card functions that are not yet
implemented.
To create a hard disk image compatible with the "330Mb Fujitsu" DIP
setting:
- chdman createhd -o [output name] -chs 1024,16,80 -ss 256 -c none
