          I would appreciate any information I could get concerning
     increasing the memory in my Z-248.  It currently has 512K and my first
     priority is to increase this to 640K.  Consequently, an extended
     memory board for this computer has to be able to perform back-fill.
     The 'official' board for doing this is the Zenith Z-405 memory board
     which has just skyrocketed to over $500!!!  A secondary item on my
     wish list is for any additional memory to be EEMS capable.

          I've tried one of the EVEREX boards advertised as being able to
     run in an AT but trying 5 different boards in 5 different Z-248s
     proved it wasn't going to work.  Jerry Pournelle wrote some months
     back in Byte that he used a Cheetah Combo board in a Z-248 and it
     worked.  I heard that AST boards are good bets for compatibility with
     the expanded memory specifications.

          Any suggestions?  Has anybody used a board in a Z-248 that cost
     less than the GNP and had it work?  Thanks in advance.
