           HP                 JETWARE               PACIFIC DATA PRODUCTS
                           (JET MEMORY)                (1-2-4 memory board)

                                                        add new chips to board

       $2000 4 Meg           Not Available              $1800  4Meg (1meg chips)
                                                             add another 2 Meg
     

The above chart should summarize it pretty much.  You may want 
to note that in terms of "bang-for-the-buck", Jet Memory may
be best.  The reason being that in general you can do all the
graphic applications with 2 Meg.  In general, you'd need 
4 Meg of memory, if you're downloading HUGE softfonts that
take up a lot of memory.  Asides from that 2 Meg is plenty
good for all 300 x 300 graphics.

Pac. Data Prod. manufactures the single board that can have
any amount of memory on it (yo uset dip switches).  In all
cases you keep the same board.  If you start with 1 Meg, and
decide to upgrade to 2 Meg, then you discard the 256K Chips
and keep the board.  Upgrade from 2 to 4 Meg is done by only
adding the chips, and resetting DIP switches.

With HP Memory Boards, as you indicated, any upgrade  would
mean throwing away what you previously had! The board and the
whole shebang :-(

Prices that I have listed are not accurate, they are only
for -- MY OWN -- comparison.

Check with the manufacturere, or your dealer for exact prices.
