 EAGLE PC+XL

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

     One user reported that to get ANY expanded memory board to work in this
     system it's necessary to solder wires on the Eagle PC+XL motherboard at
     very specific locations.

     If a customer has already purchased an Above Board or Matched Memory
     Classic and would like to try this DANGEROUS approach, they would need
     to contact an Eagle service representative for the exact locations, we
     do not have any record of these locations.

     Memory Classic.

     One user reported that to get ANY expanded memory board to work in this
     system it's necessary to solder wires on the Eagle PC+XL motherboard at
     very specific locations.

 EPSON EQUITY I

     Compatible with current Above Boards and Matched Memory Classic.  This
     computer is a PC compatible running at 4.77 MHz.  We also have reports
     that the discontinued Above Board 286, PS/286, PC, & PS/PC are also
     compatible with this computer.

     System must have ROM BIOS Ver. 2.20 to use an Above Board or Matched
     Memory Classic.

     Tech Notes:  If user has RTCDEV.SYS installed, (Epson's clock driver),
     it must come BEFORE EMM.SYS in the CONFIG.SYS!

     If an Above Board or Matched Memory Classic will be filling out
     conventional memory from 256-640K, set the motherboard switches 1-5 as
     follows - on off off on on.  This tells the system that the motherboard
     has 256K on it and could be different if motherboard has 512K.

     This system's hard disk ROM BIOS resides at C8000-CB000.  This
     interferes with the expanded memory page frame if it is located in
     lower part of the C0000 segment.  Try using CC00 for EMM's page frame
     in systems with a hard disk.

 EPSON EQUITY IE

     *CUSTOMER REPORTS* that this 8086-based computer is INCOMPATIBLE with
     current Above Boards and Matched Memory Classic.  A common symptom is
     the system won't boot with an Above Board or Matched Memory Classic
     installed.

     The Equity IE is an XT-compatible using an 8086-10 CPU, built-in VGA,
     no switches or jumpers to set on the motherboard.  Probably not
     compatible with the discontinued Above Board PC and PS/PC because of
     bus speed issues.

 EPSON EQUITY I PLUS

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

     Tech Notes:  This is an XT-compatible computer that can run at 4.77 and
     10MHz.  Customers report that the discontinued Above Board 286, PS/286
     also work fine.  Probably not compatible with the discontinued Above
     Board PC and PS/PC due to the higher speed.

 EPSON EQUITY II & ABS

     *CUSTOMER REPORTS* of compatibility with current Above Boards and
     Matched Memory Classic.  Customers report compatibility with the
     discontinued Above Board 286 and PS/286 also.

     Tech Notes:  The Equity II is an NEC V20-based system that can run at
     either 4.77 or 7.6MHz.  Customers report that an Above Board PC and
     PS/PC will work at the 4.77MHz speed ONLY.  Above Board PC and PS/PC
     may have problems at high speed.  Must have jumpers J1 and J2 in
     Position 2 in order for machine to recognize expansion boards.

     System uses an NEC V20 processor instead of an 8088 or 8086.  You
     cannot use BOTH an 8087 and an Above Board or Matched Memory Classic in
     the system together.  At one point we heard Epson discussing an upgrade
     to allow both an 8087 and expanded memory to operate together in this
     computer, but we don't know the final status on this issue.  The
     customer would need to contact Epson for upgrade status.

 EVEREX 1600B

     *CUSTOMER REPORTS* of compatibility with current Above Boards and
     Matched Memory Classic.  The Everex 1600B is an 8088-based system that
     is 4.77/12MHz switchable.  The discontinued Above Board PC and PS/PC
     will fail at the 12MHz speed.

     Everex's phone number is ph: (415) 498-1115

 IBM 3270 PC

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

     Tech Notes:  3270 Control programs use LOTS of conventional memory.
     This may affect Lotus 123 Rel 2.x and other programs that need
     conventional memory to address expanded memory.

     If using the QUIKBUF print buffer, put QUIKBUF AFTER 3270 control
     programs in the AUTOEXEC.BAT file.

     With the 3270 control programs turned OFF, the 3270 PC functions as a
     normal PC/XT.

 IBM 3270 PC W/ EXPANSION BOX

     *CUSTOMER REPORTS* that current Above Boards and Matched Memory Classic
     work when installed in the Expansion box attached to a 3270 PC.

     ** NOTE **  When user runs CHKMEM, he may see less than 640K
     conventional if the 3270 software has been loaded.

 IBM 3270 PC & TESTAB

     Symptom is that TESTAB shows all memory on the Intel Memory Board as
     being defective.  This is due to a conflict between the TESTAB program
     and the 3270PC environment, it does not reflect the actual status of
     the board.

     Since TESTAB is not reliable in this system, it may prove necessary to
     move the Above Board or Matched Memory Classic to another system to
     test it.

 IBM 3270 PCG

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

     Use the IBM Graphics Control program version 1.12 or newer when using
     expanded memory.

 IBM PC-1

     Compatible with Above Board ISA, Plus 8, Plus, and the Matched Memory
     Classic Boards, as well as the discontinued Above Board 286, PS/286,
     PC, and PS/PC.

     System motherboard only has 64K.  Must fill the motherboard to a
     minimum of 256K with another board before using an Above Board ISA to
     fill remaining conventional memory.  Make sure ALL sockets on any
     additional board(s) are full before filling to 544k with any add-in
     card.  Often this results in 320K.  Intel memory cards CANNOT backfill
     from 320K, so they should use another board to backfill conventional
     memory to either 512K (where the Above Board ISA can start) or all the
     way to 640K.

     Maximum conventional memory for this system is 544K.  System can be
     upgraded to allow 640K by replacing the ROM BIOS chip.

 IBM PC-2

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

 IBM PC/XT

     These 8088-based computers are compatible with the Above Board ISA,
     Plus, Plus 8, and the Matched Memory Classic Boards. Also compatible
     with this system are the discontinued Above Board 286, PS/286, PC, &
     PS/PC.

     Tech Notes:
     A no-boot condition can occur if the Above Board ISA is configured for
     I/O address 210-217, (as BOARD #4).  Refer to the Above Board ISA
     installation guide for information on setting the switches for the I/O
     address.

 IBM PORTABLE PC

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

 IBM XT 370

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

 IBM PS/2 MODEL 25

     Compatible with current Above Boards and the Matched Memory Classic
     boards, (although NOT compatible with the discontinued Above Board PC
     and Above Board PS/PC because of the higher bus speeds).

     This 8086-based computer operates at 8MHZ. It's an educational version
     of the Model 30, and since it has only one disk drive INSTALL or
     SOFTSET cannot be used.  To open the system, you must turn it on its
     side and the bottom swings away from the chassis.  There are 2 slots.

     The outside slot is for half boards and the inside slot is for full
     length boards. Place the Intel memory board in the inside slot and move
     the disk controller to the outside slot.

 IBM MODEL 30

     This 8086-based computer is compatible with the Above Board ISA, Plus,
     Plus 8, and the Matched Memory Classic boards. Also with the
     discontinued Above Board 286 & PS/286. The discontinued Above Board PC
     and PS/PC are NOT compatible because of the higher bus speed (8MHZ).
     The discontinued Above Board AT and PS/AT are NOT compatible because
     they are 16bit ONLY cards and the IBM Model 30 only has an 8bit bus.

     Installation procedures:
     1.  Use the PC Selection Plug on the Intel memory card or set switch #4
         on the Above Board ISA to Off.
     2.  Run Setboard and specify a Model 30 system.
     3.  They need 4.0 EMM for Install to work properly.  If they have a
         pre-4.0 EMM, they will need to do a manual install.
     4.  Parity errors will not be caught by power-on test with EMM 3.5 so
         be sure user is aware of this.  Send them EMM 4.0.

     Tech Notes:
     Quarterdeck's QRAM v2.0 in the IBM Model 30 requires the NOXBDA
     parameter on the QRAM.SYS device driver line in the CONFIG.SYS file.
     NOXBDA stands for No Extended BIOS Data Area.  If the NOXBDA parameter
     is not present, QRAM will attempt to relocate it resulting in a system
     lockup.  MOVE'EM from Qualitas may have a similar command.

 IBM 3270 PC & QUIKBUF

     Put Quikbuf AFTER 3270 control programs in Autoexec.bat file.
