- Husky Hunter, Hunter 2
-
- http://www.seasip.info/VintagePC/husky2.html
-
- 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'.
-
- TODO:
- - Add ports 83 and 85
- - Need software
- - Add whatever image devices existed
- - Probably lots of other stuff
