2. SYSTEM MICROCOMPUTER
The system microcomputer QL01 employs an 8 bit micro-
controller (M38002SFP).
In this system microcomputer, a program area provided
inside the computer is not used but an external program
ROM (QL02, NM27C256Q) is used.
This allows easy maintenance of the system when specifi-
cation modification, bug correction, etc. will occur.
Table 5-1 shows the terminal function of the system mi-
crocomputer.
