The memory is standard 1 x 8, 70ns, 72-pin JEDEC SIMMS.  System accepts 4,
8, 16, and 32 MB SIMMs.  4 MB of memory is soldered on the motherboard.

When upgrading the memory on your AST Advantage! computer, the following 
memory modules are available from Tandy National Parts:

4 MB SIMM        National Parts #  AX2505138
8 MB SIMM        National Parts #  AX2509988 (32 Bit SIMM)
                 National Parts #  AX2597220 (36 Bit SIMM)
16 MB SIMM       National Parts #  AX2509987
32 MB SIMM       National Parts #  AX2509976

To add a SIMM, or to remove an existing SIMM and replace it, complete
these steps:

    1.  Turn the computer off, unplug the power cord, disconnect all
        peripheral devices, and remove the system unit cover.

    2.  Locate the memory bank (U30) on the system board.  

    3.  If necessary, remove any add-in boards that block easy access to
        the SIMM banks.

    4.  If you need to remove a SIMM, carefully pull the retaining clips
        from the edges of the SIMM.  At the same time, push the SIMM
        slightly forward from the back.  Remove the SIMM carefully to
        avoid damage.

    5.  To install a SIMM, slide it into the first empty bank and push
        it back until the retaining clips snap into place.  Make sure
        the SIMM is securely in its bank.

    6.  If you removed any add-it boards to reach the SIMM banks, replace
        the add-in boards.

    7.  Replace the system-unit cover.  Reconnect peripheral devices and
        plug in the power cord.  Turn on the system.
