I honestly never understood the C128.
The C64 focused on graphics and sound.
With the C128, you got a additional processor (a rather slow Z80) and CPM support?
Uh, wtf?
CPM had basically no support for graphics or sound.
Most of Bill's work is like that. Pointless derivations of the C64 that weaken the design.
Get your self a Valium!, sounds like u need it.
