Brief information
Internal memory card and switched clock generators.
Specification
- 1 MB SRAM, optionally 2 MB, in banks of 64KB,
- 512 KB FlashROM, 8 banks of 64 KB with the option of individual switching off, EXOS in bank 7 (always on),
- RTC clock,
- NVRAM (battery backup),
- two-channel synchronized clock signal generator:
- system clock 4/8/12/16/20 MHz (2/4/6/8/10 MHz Z80 CPU),
- EXDOS clock 8/9.6/10/12/13.33/16 MHz
- LCD or OLED display (2x16 chars),
- RGB LED to signal by colors the selected CPU clock:
- 2MHz blue,
- 4MHz green,
- 6MHz yellow,

Clock selection
DS1 | DS2 | Work mode |
---|---|---|
ON | ON | EnterMice native mouse mode |
OFF | ON | BoxSoft compatible mouse mode. The two main buttons are swapped. Main now is the right one. |
OFF | OFF | EnterMice joystick mode (Movement made to the mouse is redirected to the input of Joystick 1, and that port is disabled) |
ON | OFF | not used (in fact EnterMice as joystick on KB K column) |
