 ACER 710

     *CUSTOMER REPORTS* of compatibility with current Above Boards and
     Matched Memory Classic.  Probably not compatible with the discontinued
     Above Board PC or PS/PC due to the fast bus speed).

     The ACER 710 is a dual speed XT compatible system (4.77 & 10MHz).  This
     system allows up to 768K of conventional memory.  Memory above 640K
     must be disabled to make room for an expanded memory page frame.  Set
     switch #6 on motherboard switch block 3 to the OFF position to disable
     memory from 640K to 768K.

 ALEX TELECOMPUTER

     *CUSTOMER REPORTS* of compatibility with current Above Boards and
     Matched Memory Classic.

     This system is an XT compatible and is reportedly made by Compaq.

 ALPHA NUMERICS PC CLONE

     *CUSTOMER REPORT* of LIMITED COMPATIBILITY with current Above Boards
     and Matched Memory Classic.  Alpha Numerics PC clone can run at 4.77 or
     8MHz and fails at the 8MHz speed with an Above Board.  An Above Board
     worked fine at the 4.77MHz speed.  A Quadram board wouldn't even work
     at the 4.77MHz speed!  The system has an Excel motherboard.

     Symptoms include TESTAB showing all chips bad, and when the customer
     tried to load SK+, a message would come up saying some of the pages are
     bad in expanded memory.

 ALR TURBO

     *CUSTOMER REPORT* of compatibility with current Above Boards and
     Matched Memory Classic.  This is an XT-Compatible computer.

     Tech Notes:  We have customer reports of compatibility with Above Board
     PC and PS/PC at both 4.77MHz and 8MHz system speeds.  We are not sure
     if the 8MHz speed affects the data bus or not, it doesn't appear to.

     This computer is switchable from 4.77MHz to 8MHz with a hardware
     switch. The system board holds up to 768K and can be set for 640K or
     768K.  Fill the system board memory to 640K before using an Above Board
     or Matched Memory Classic board.

 AMDEK SYSTEM 88

     *CUSTOMER REPORT*  The Amdek System 88 is INCOMPATIBLE with Above
     Boards and Matched Memory Classic.

     This computer has an 8088 back-plane card and 16 bit slots.  Two
     different Above Boards would not work in this system.  The EMM.SYS
     driver gave an error saying that there was no expanded memory to manage
     and TESTAB showed all chips bad.

 AMERICAN COMPUTER & PERIPHERAL

     *CUSTOMER REPORT* of LIMITED COMPATIBILITY with Above Boards and
     Matched Memory Classic.  One customer reported that they could not do
     warm boots with the EMM.SYS driver installed in this XT-Compatible
     computer.  The Above Board functioned properly otherwise.

 AT&T 6300

     This 8086-based computer is compatible with current Above Boards and
     the Matched Memory Classic.  The discontinued Above Board 286, PS/286,
     PC, and PS/PC are also compatible.  The AT&T 6300 runs an 8MHz data
     bus.

     Tech Notes: Generally, it is recommended to install an Above Board in
     an IBM-type 8-bit slot.  If the system has 256K on the system board and
     the AT&T expansion board is being used to provide additional
     conventional memory, you will not be able to use an Above Board or
     Matched Memory Classic board to backfill conventional memory.

     If parity errors occur with an Above Board PC or PS/PC:
         Make sure the memory chips are on the approved chip list.
         If the chips are 200ns chips, try using 150ns chips.
         Try installing the Above Board PC or PS/PC in a different slot,
         (including one of the 6300's 16-bit slots.)

 AT&T 6300WGS

     *CUSTOMER REPORTS* that Above Boards and Matched Memory Classic are
     INCOMPATIBLE with AT&T's 6300WGS computers.

 COLUMBIA 1600 PC

     *CUSTOMER REPORTS* if compatibility with current Above Boards and
     Matched Memory Classic.  Reports indicate that the Above Board 286,
     PS/286, PC, and PS/PC are also compatible.

 COMPAQ DESKPRO

     Compatible with Current Above Boards and Matched Memory Classic.  Also
     compatible with the discontinued Above Board 286, PS/286, PC and PS/PC.

 COMPAQ PORTABLE

     Compatible with Current Above Boards and Matched Memory Classic.  Also
     compatible with the discontinued Above Board 286, PS/286, PC and PS/PC.

 COMPAQ (PORTABLE) PLUS

     Compatible with current Above Boards and Matched Memory Classic.  Also
     compatible with the discontinued Above Board 286, PS/286, PC and PS/PC.

 COMPAQ TELECOMPAQ

     Compatible with current Above Boards and Matched Memory classic.  Also
     compatible with the discontinued Above Board 286, PS/286, PC and PS/PC.

     Tech Note:  If running the TESTABPC that shipped with the Above Board
     PC, use override to manually choose D8000 for the page frame.  Using
     automatic page frame selection will not work.

 CORONA PC

     Compatible with current Above Boards and Matched Memory Classic.  Also
     compatible with the discontinued Above Board PC and PS/PC.

     Some Corona machines install a screen driver at 512K.  To disable this,
     (so an expansion board can fill conventional memory), change the MODE
     command in the AUTOEXEC.BAT to MONO.

 CORONA PC PORTABLE

     Compatible with current Above Boards and Matched Memory Classic.  Also
     compatible with the discontinued Above Board PC and PS/PC.

     Some Corona machines install a screen driver at 512K.  To disable this,
     (so an expansion board can fill conventional memory), change the MODE
     command in the AUTOEXEC.BAT to mono.

 CORONA DOS 3.1 & CLOCK.SYS

     The Above Board PS/PC CLOCK.SYS driver will always return Msg. 101 on
     boot up.  Corona DOS 3.1 apparently resets the clock chip on the Above
     Board PS/PC.  Using debug to initialize the clock chip will not work
     because DOS undoes it when you boot.  May want to try using MS-DOS or
     PC-DOS.  Lower versions of Corona DOS potentially have the same problem
     but this is unknown at this time.
