15.4 Control board
The control board, with Flash technology, is inserted in the Rack next to the I/O board; its
function is to control the machine and its peripherals. It has two parts:
Ô The circuit that contains the micro-controller (MCF5206e) and the flash memory
(29LV400 4 Mbit).
Ô The circuit that contains the RAM memory (68AW511 of 512KBytes) and the eeprom
memory (24C64 of 64 Kbit).
