/* [John Elliott, 15 July 2001]
|
|
* Copied this file into ZXCC, a CP/M emulator.
|
|
* Since ZXCC's memory is a flat 64k space and will never be bank-switched,
|
|
* the bank-switching code is removed.
|
|
* Since ZXCC has no memory-mapped screen, all the screen management code
|
|
* goes as well.
|
|
* Since ZXCC doesn't need its speed regulated, all the speed regulation
|
|
* code goes as well.
|
|
* Since ZXCC doesn't save or load snapshots... OK, you get the idea.
