|

// What's in:
|
||||||
|
// - Emulation of both 5061-3001 CPUs
|
||||||
|
// - LPU & PPU ROMs
|
||||||
|
// - LPU & PPU RAMs
|
||||||
|
// - Text mode screen
|
||||||
|
// - Keyboard (most of keys)
|
||||||
|
// What's not yet in:
|
||||||
|
// - Beeper
|
||||||
|
// - Rest of keyboard
|
||||||
|
// - Graphic screen
|
||||||
|
// - Tape drive (this needs some heavy RE of the TACO chip)
|
||||||
|
// - Better documentation of this file
|
||||||
|
// - Software list to load optional ROMs
|
||||||
|
// What's wrong:
|
||||||
|
// - I'm using character generator from HP64K (another driver of mine): no known dump of the original one
|
||||||
|
// - Speed, as usual
|
||||||
|
// - There are a couple of undocumented opcodes that PPU executes at each keyboard interrupt: don't know if ignoring them is a Bad Thing (tm) or not
