/******************************************************************************************************
Motorola M68HC05EVS evaluation system
Chips:
Main board: XC68HC26P, R65C52P2, MS62256l-70PC, MS6264L-70PC, eprom. Xtal = 3.6864MHz
Emulator board: MC68C705P9CP, undumped 28-pin prom. Xtal = 4MHz
R65C52 = Dual ACIA with inbuilt baud rate divider, uses 8 addresses, uses the 3.6864MHz crystal
XC68HC26P = PPI (3 ports), uses 8 addresses.
2014-01-12 Skeleton driver
The rom is larger than the available address space, but not all of it is programmed. The code
ranges are 800-18FF,1FF0-1FFF. There must be a banking scheme in use.
Memory map guess
000-07F Stack (and user ram?)
080-0FF RAM (or devices?)
100-FFF ROM
ToDo:
- Everything
