1. Printer's Memory
Continued!
The printer's memory is divided in a number of parts, or directories:
• Read-Only Memory ("rom:")
This directory is designated "rom:" and consists of the 2, 4 or 6
EPROM packages fitted on the printer's CPU board plus any non
DOS-formatted memory card inserted in the printer's optional
memory card adapter. As the name implies can this part of the
memory only be read from, but not written to.
• Random Access Memory ("ram:")
The RAM memory is designated "ram:" and consists of 2 or 4
RAM packages fitted on the printer's CPU board. The RAM
memory can both be read from and written to.
• Memory Cards: ("card1:")
The RAM memory can be supplemented with a DOS-formatted
memory card that is inserted in the printer's optional memory card
adapter. Such a card is referred to as "card1:" and can be both read
from and written to. (Note the distinction between DOS-formatted
and non DOS-formatted memory cards).
