CHANGE RAM
The Model 3000B system allows the operator to change the RAM of the handler CPU. To access the
Change RAM Mode of the Model 3000B:

2. Press [SET UP] again to toggle the YES/NO option to YES. The message CHANGE RAM? YES will
appear.
3. Press [Enter]. The message LOAD DEFAULT NO will appear. If you choose LOAD DEFAULT NO
the handler will leave all RAM addresses as they were. From LOAD DEFAULT NO you may proceed
in either of two directions:
A. If you wish to make specific changes to the RAM and do not wish to load the default values,
press [Enter] again. The display will read, 0090 DATA 01 Proceed directly to step 4 of this
procedure.
B. If you do wish to set the RAM with ROM values, press [SET UP] to toggle the YES/NO option
of the LOAD DEFAULT message to YES. Press [Enter].

BLASTING THE RAM

When you choose LOAD DEFAULT YES the handler loads all default addresses from the
EPROM to the RAM. After loading the EPROM into the RAM, you may still make specific RAM
changes as described below, if you wish. Or you may proceed directly to step 5.

[Delete] button to increment the lower data nibble in any individual address as desired.
♦ Press the minus button, [-], to set a specific address to FF.
♦ Press the zero key, [0], to set a specific address to 00.

[Clear] button to load the default value from the EPROM into the RAM for a specific
address only.
