Just a note. If you have some instruments such as oscilloscope or even a logic analyzer, the VME bus is a very straight forward bus so debug on.


A little bit odd that they seems to wrote the same data as the address itself and they expect 0xaaaaaaaa,. Usually when running test you try 0x5 and 0xa as one pattern but 0x40000 odd

A instrument like this is perfect for the job there is also a G version without the crappy oscilloskop, i would for the G version.

At the moment I consider myself a fool concerning this complex level of electronics, and a fool with a tool....
