/***************************************************************************
- Skeleton driver for Husky Hunter 2
-
- 2014-03-06 Skeleton [Robbbert]
- 2014-03-07 Fixed screen [Barry Rodewald]
- 2014-03-07 Added more stuff [Robbbert]
+ Husky Hunter, Hunter 2
http://www.seasip.info/VintagePC/husky2.html
- No schematics or manuals available.
+ The main hardware difference between the original Hunter and Hunter 2 is
+ the LCD panel, in the Hunter 2 it is physically larger. It is also driven
+ differently. The Hunter sets up the HD61830 number of time divisions to
+ be 32 and uses both address counters RAC1/RAC2, whereas the Hunter 2 sets
+ number of time divisions to 64 and only uses RAC1 to address the upper half
+ of the screen.
+ Early models would use all 6 ROM sockets to provide 48K ROM (6 x 2764),
+ whereas later models would populate 2 sockets with 2 x 32K ROM (TC57256),
+ though only 48K of this is ever paged in.
+
+ Usage:
+ The RAMdisk must first be formatted using 'format'.
