S2 robot rom use
Recently aquired one of these from ebay.
All works perfectly.
The problem is every time I power it up, before I download my program to ram, the robot goes into one of its pre-programmed routines. It stops as soon as I download a program but it is irritating. I could erase the eeprom but I do not want to disturb the existing code. There are two eeproms at different addresses 0 and 1. I guess the code is in the rom 0. I contemplated lifting pin 1 (A0) of each chip and wiring to a dip switch to be able to arrange for the blank eeprom to be at address 0 to stop the autoplaying. I wonder what other people do- or do they just overwrite the original code. I can find only the 'getting started' and 'circuit diagram' documents for the S2.
Thanks in advance
