COPYING MESSAGE TEXTS INTO EPROM
The texts entered using pocket keyboard LCA 010 are
stored in a battery-backed-up RAM. They can be deleted,
edited or expanded as often as you wish.
The contents of the RAM can be rapidly copied into an
EPROM using EPROM programmer LCA 014:
1. Program initialization and message texts using the
pocket keyboard.
2. Plug an empty EPROM 2764 (e.g. LCA 048) into the
LCA 014 socket.
3. Using the LCA010 invoke program 8 in text display
LCA 014.
4. Plug programmed EPROM into socket of LCA 042.
As long as there is an EPROM in the LCA 042, its contents
are valid and the LCA 010 is not accessed. If the EPROM is
removed, the contents of the RAM become valid. With
program 8 (READ EPROM) the contents of an EPROM can
also be copied into the RAM.
