Protect Switch
When the RAM of the PC-8201 has been expanded by the addition
of CMOS 8Kbyte chips (PC-8201-06), or with a RAM Cartridge
(PC-8206), extra memory banks become available for use.
The Protect Switch, set to the ON position, prevents data from being
entered into Bank #2, so there is no way that the data in the bank
could be "written over".
Bank #3 is protected by a similar protect switch located on the side
of the RAM Cartridge (PC-8206). This protect switch is the only
switch located on the cartridge.
The main Protect Switch on the back of the PC-8201 should be eft
ON whenever you want to protect vital data. If you want to access
the data in Bank #2 then the Protect Switch must be turned OFF.
The protect switch on the RAM Cartridge operates in the same
manner as the main Protect Switch.
When you are turning the protect switch of the RAM
Cartridge ON be sure that the power of the PC-8201 is
turned OFF.
Bank #1 is unprotected. Since data could be "written over" in
Bank #1, it is recommended that all important programs and files be
stored in Banks #2 and #3.
