Hi Bob,
of course it is possible, or at least it was. The thing is caled "EMK1" and is
an upgrade (expansion memory kit) for most of the DKV units. It has 15Mb onboard
and with your 1Mb you get a total static RAM of 16Mb! Thats as much as the
actual MarkIII generation has. The EMK1 is a memory borad which you have to
exchange for an existing on in your unit!
WIth luck you you can get one because they have become rare, I think.
