/***************************************************************************
SacState 8008
23/02/2009 Skeleton driver.
http://www.digibarn.com/stories/bill-pentz-story/index.html
The year is listed as '1972/73'.
All input to be in lowercase.
The weird characters that show on screen are various escape sequences.
These are different depending on the terminal type chosen. The codes
need to be understood and emulated before this system makes sense.
Known Monitor commands: (from the disassembly)
! write buffer to AD000
* set RAM036 flag
+ increment AD000 by 1
+n increment AD000 by n
- decrement AD000 by 1
-n decrement AD000 by n
: clear RAM036 flag
= display AD000
=nnn set AD000 to nnn
@ fill buffer with 026
unknown commands: / & d e l r s t u z \ ^ | ~
Other input will either result in '!' message, or halt.
