The board comes with the following features:
|
||||
- 6502A processor, at 2MHz (slowed to 1MHz during i/o accesses)
|
||||
- 6522 versatile interface adapter for timers and interruptible latched i/o ports
|
||||
- Interface for a 20x4 LCD display
|
||||
- 32kbyte high speed SRAM
|
||||
- 128kbyte in circuit programmable flash ROM (16k for main operating system, 112k for other ROM based applications)
|
||||
- PS/2 keyboard interface
|
||||
- Real time clock (year 2000 compliant), on a shared I²C bus
|
||||
- Full implementation of the BBC micro's 1MHz expansion bus for add on boards
|
