Could this happen if the A2630 shunt block was set at 4 meg even though
only two meg was only board.

What sort of software You mean the GVP ROM?

Sorry to whine on but this is important as I am just about to order an 
A2630 but I would like to know. 
I mean I would like to know how I can get the maximum contiguous mem with
my A2360 (with 2 meg or 4 meg) and my GVP HC+8 (with 6 meg or 4 meg)
and would the contiguous mem belimited to the maximum of the first
configured card , in any case , the A2630. Would the the congig
be A2630, GVP hard disk controller, GVP RAM card (on one board)
therefore the GVP board controller stopping the GVP RAM from following
straingt into the A2630 RaM
