REFERENCE DATA
Here we are introducing newly adopted parts for DSS-1 mainly. However, please note, though they are same name,
such as CPU8085, processing speed of the one for DSS-1 is much faster than the one for POLY-800 and not compati
ble each other. If misused, malfunction will happen. For those parts in replacing and ordering, please refer to our parts
list. They are listed separately with different code number.
