Hi everyone,
I've been using few different MCUs but never Atmel or 8051.
I've been handed couple of simple display boards which use AT89C2051 as controller.
What do i need to get started right away? What software and what hardware?
Pins 6 and 9 of MCU are accessible on a connector.
more details if you are interested:

units are not programmed. i'd prefer C but ASM will should do too.
All i need is receive message (RS485) and drive display. driving display is dead simple (4x 74HC595 and ULN2803), getting serial to work should not be much trouble either (one RS232 port is integrated with MAX232; RS422/485 ic sockets are empty since optional, i am waiting for 75156 chips to plug them in)
