RML380Z ROM images

[Jules Richardson]

Does anyone happen to have ROM dumps of from the RML 380Z CPU board? 

All three 2716's on the board in front of me seem to have gone blank.
(I've verified that the 2716 chargen ROM from the video board reads OK,
so it's not my programmer failing to read properly!)

The three ROMs in question are labelled "4.0B" (M0, M1 and M2). 

My 380Z fileserver won't have the same ROMs in it, and my own 380Z
'desktop' only has a pair of ROMs in it labelled "3.4E".

ps. are 2716's known for failure in this way?

cheers
