║ Above Board 8088-Based Computer Compatibility: A-C ║
║ ║
╚═════════════════════════════════════════════════════════════════════════╝
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.
ALR's BBS phone number is ph: 714-458-6834 (4/27/90)
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.
