21MX/E FAB

[Jay West]

In pouring over the documentation for the 13304A (FAB), I find one thing
unclear. Is there a way to disable a given block? Empirically, it seems that
if you have roms in a given block they are going to get mapped SOMEWHERE,
depending on the jumpers and if you don't have roms in a given block you
don't have to worry about setting jumpers to disable that block. But I was
curious if there was a given jumper combination for a block to disable it -
without having to pull the roms. Not a huge deal, just curious, and I don't
see it in the docs. Any thoughts?

 

Best,
