I put the memory then the cpu then the RXV21 and finally the RQDX3.
System boots from the RX50 and the RD53 just fine.
Now I need to run diagnostics on the RXV21 and then the RX02.
As usual the manual tells you everything you dont need to know,
I thought L RXDIAG then CR and S but no the prog. was not on yhe disk.
Suggestions on testing RXV21 please
