I am trying to troubleshoot a PC10 pcb for a fellow KLOV'r.
The 8pin PROM at U4 (see pic below for an example) on the PCB is bad. I am trying to see if I can simply dump the image from a working U4 PROM and reburn.
I am not sure what the nomenclature of the chip it is as I cannot see any markings. I saw a reference to an 8pin security chip (RP5H01) at http://playchoice.riemen.net/downloads/RP5H01.pdf and believe this is it.
Can anyone confirm that U4 is an RP5H01? Also, would I be able to simply dump the image from a good chip and burn to a blank RP5H01? If so, where could I purchase a blank RP5H01?
Thanks.
