COMPUADD 286
*CUSTOMER REPORTS* that this 80286-based system is compatible with current
Above Boards and Matched Memory classic.
This system has 640K conventional and 384K extended memory on the
motherboard and comes with an 8-bit EGA board.
Tech Notes: One customer reported video garbage with their Above Board
I/O base address set to 208. Changing the I/O address to 258 by running
SETBOARD in another system fixed the problem.
CORDATA 4200 (DESKTOP MODEL)
*CUSTOMER REPORTS* that this 80286-based system is compatible with current
Above Boards and Matched Memory Classic.
Customer reports and a report from Cordata say that the Above Board AT and
PS/AT are INCOMPATIBLE.
CORDATA AT PORTABLE
We currently have no information about compatibility with this system and
current Above Boards or Matched Memory Classic. However, we do have
*CUSTOMER REPORTS* that the Cordata AT Portable is INCOMPATIBLE with the
Above Board AT & PS/AT for expanded memory. The Above Board AT & PS/AT
could be used for extended memory in this system.
CORONA DATA 286
*CUSTOMER REPORTS* of INCOMPATIBILITY with Above Boards and Matched Memory
Classic. This system has a 0 wait state data bus with NO provisions to
configure it for 1 wait state. A system running at 0 wait states violates
the IBM specification of 1 wait state and is not fully IBM compatible.
Intel classic bus memory boards require the IBM standard of 1 wait state
The symptom that customers reported was stray characters appearing on the
screen when the Above Board was providing memory.
DATAFOX (AT CLONE)
*CUSTOMER REPORTS* that this 6/10MHz 80286-based system is compatible with
current Above Boards and Matched Memory Classic. We also have reports
that the discontinued Above Board AT & PS/AT worked in this system when
the system was set to operate at 6MHz.
This system has a jumper on the motherboard to select either a non-IBM AT
standard 0 wait state data bus speed or the IBM AT standard 1 wait state
data bus speed. This Jumper must be set for 1 wait state for an Above
Board or Matched Memory Classic to function properly since these boards
adhere to the IBM standard of 1 wait state.
DEC VAXMATE
*CUSTOMER REPORTS* of LIMITED COMPATIBILITY with Above Boards. The DEC
VAXMATE without an expansion chassis has no slots. You must have the DEC
VAXMATE expansion chassis to use an Above Board or Matched Memory classic.
The DEC Vaxmate motherboard memory is divided as 640K base and 384K
extended. We have reports that an Above Board 286 worked fine as expanded
memory but would not work as extended memory. CHKMEM would not recognize
the 384K of extended memory on the motherboard. We have no direct
compatibility information on this system with our current Above Boards or
Matched Memory Classic.
DELL 220
*CUSTOMER REPORTS* that this 80286-based system is compatible with current
Above Boards and Matched Memory Classic.
The Dell 220 runs the processor at 20MHz but runs the data bus at 8MHz.
The motherboard can supply expanded memory which must be disabled before
an Above Board or Matched Memory Classic can provide expanded memory. To
disable the motherboard expanded memory you need to download a program
called "EMSOFF.COM" from Dell's BBS.
DELL 200
*CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
Memory Classic.
System runs at 12MHz but if odd errors occur, try running SETBOARD for
8MHz.
In the case of the PC's Limited 286/12MHz, run SETBOARD for 12MHz.
Many of these systems are showing up in customers' hands with 16-bit VGA
boards which need to be set to 8-bit mode if an Above Board or Matched
Memory Classic is being used to provide any exPANded memory. This is not
necessary if the Above Board or Matched Memory Classic is providing only
extended memory. In some cases it is necessary to add the parameter
EXPF=D000 to the EMM.SYS command line. Must be using the Classic Bus EMM
ver 4.0 rev C (4/89) or later.
DS SQUARED
*CUSTOMER REPORT* of LIMITED COMPATIBILITY with Above Boards and Matched
Memory Classic. This is a 286-based system running at 10MHz CPU speed.
Probably not compatible with the discontinued Above Board AT and PS/AT due
to the fast bus speed.
From a customer report, the Above Board, (or Matched Memory Classic), can
provide exTENed memory in this computer without any problems. However, if
the Intel EMM.SYS driver tries to load, the computer locks up. Intel is
unable to determine the conflict. Apparently there was either an expanded
memory manager in ROM on the motherboard that our driver was conflicting
with, or some other conflict with the motherboard.
DTK 286 MOTHERBOARDS
We have *CONFLICTING CUSTOMER REPORTS* about compatibility with current
Above Boards and the Matched Memory Classic in DTK 286 computers.
If experiencing intermittent PARITY CHECK 2 errors or EMM.SYS errors at
boot, run SETBOARD again and specify a 6/8MHz bus. Even though this
system runs at 10MHz, running SETBOARD for a 6/8MHz bus appears to be the
only way to get it to work according to customer reports.
We have also received fairly consistent reports that these system boards
use I/O port address 208. Choose an I/O address other than 208 when
setting up an Above Board or Matched Memory Classic!
We have one *CUSTOMER REPORT* of INCOMPATIBILITY with a DTK 286 having 1Mb
on the system board. The system would only recognize the first 64Kb of
Above Board memory. This particular system board had speed settings for
10MHz/0 wait states, or 6MHz/1 wait state. Even with the system board
configured for 6MHz/1 wait state the Above Board wasn't recognized.
EASYDATA 286 216I
*CUSTOMER REPORT* of compatibility with current Above Boards and Matched
Memory Classic. System bus speed is 10MHz. Probably not compatible with
the Above Board AT or PS/AT due to the fast bus speed.
EPSON EQUITY II PLUS
*CUSTOMER REPORTS* that this 80286-based system is compatible with current
Above Boards and Matched Memory Classic. Some reports indicate problems
with an Above Board or Matched Memory Classic set for extended memory.
Make sure bus is set for 1 wait state.
This computer can operate at 8, 10, or 12MHz. There are jumpers on the
motherboard for wait states, this computer can operate at 0 wait states or
the IBM standard of 1 wait state. Small footprint computer, (very
confusing since the Epson Equity II is an 8 bit machine!)
EPSON EQUITY III
*CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
Memory Classic. We also have reports that the Above Board 286, PS/286, AT
and PS/AT are also compatible. The data bus in this system runs at 8MHz.
EPSON EQUITY III PLUS
*CUSTOMER REPORTS* that this 80286-based computer is compatible with
current Above Boards and Matched Memory Classic. This computer is capable
of switching speeds, (there are two versions of this computer: 6, 8, or
10MHz, and 6, 8, or 12MHz).
The Above Board 286 and Above Board Plus were tested on the 10MHz version
of this computer with both 120 and 150 nanosecond memory chips and are
fully compatible. We have not tested the 12MHz version but have *CUSTOMER
REPORTS* that they work fine with Above Board 286, Plus, Plus 8, and
Matched Memory Classic.
If the system is being run faster than 8MHz clock rate, user must run the
MANUAL SETUP in SETBOARD, (or Technical Setup in first version of SETBOARD
shipped with the Above Board 286), and set the Above Board or Matched
Memory Classic to the appropriate speed.
One customer reported that an Above Board AT worked in this computer.
REMEMBER, the Above Board AT and PS/AT are NOT GUARANTEED to work above
8MHz. If they already have an Above Board AT or PS/AT, recommend setting
the front panel switch on the system to 6 or 8 MHz ONLY.
EPSON IIE
Compatible with current Above Boards and Matched Memory Classic.
This is a turbo system with a switch on the front that takes it back and
forth from 8MHz to 12MHz. The BUS seems to always run at 8 MHz, 1 wait
state, (the IBM standard), regardless of the system speed.
Tech Notes: The video board is actually a Paradise VGA Plus with Epson's
name on it, so it will be necessary to put it into 8-bit mode if an Above
Board or Matched Memory Classic is providing exPANded memory. BIOS size
is 32K, (C0000-C7FFF.) RAMBIOS.SYS will run the BIOS from conventional
memory. We have *CUSTOMER REPORTS* that it is not possible to disable
conventional memory on the motherboard for support of mappable
conventional memory to be provided by an Above Board Plus, Plus 8, or
Matched Memory Classic.
EVEREX
EVEREX 1700A
*CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
Memory Classic. This is an 8-10MHz switchable 80286-based computer.
EVEREX 1700C
*CUSTOMER REPORTS* that this 80286-based computer is compatible with
current Above Boards and Matched Memory Classic boards. This system is
switchable between 8-12MHz.
EVEREX 1800
*CUSTOMER REPORTS* of compatibility between the following Everex 1800
series 80286-based computers and current Above Boards and Matched Memory
Classic:
There are several different versions of this 80286 computer:
1800R- oldest system, it can be either a 6 or 8mhz system
1800A- 8-10mhz switchable system
1800B- 8-10mhz switchable system
1800C- 8-12mhz switchable system
EVEREX 1800S AT COMPATIBLE
*CUSTOMER REPORTS* that the Everex 1800S is INCOMPATIBLE with the Above
Board 286. HOWEVER, one caller talked to Everex Support and was told that
they would need a "PAL Chip Upgrade Kit" if they were planning on using an
Above Board. Since the Above Board Plus, Plus 8 and Matched Memory
Classic function in the same manner as the Above Board 286, they are
probably INCOMPATIBLE as well.
EVEREX STEP 286-15
*CUSTOMER REPORT* of compatibility with Above Boards and Matched Memory
Classic. A customer reported the processor runs at 8, 12, or 15MHz, but
the data bus runs at 8MHz.
FRANKLIN FT-286
*CUSTOMER REPORTS* of compatibility with current Above Boards and Matched
Memory Classic. Reports also indicate compatibility with the discontinued
Above Board 286, PS/286, AT, and PS/AT. This is a 6/8MHz AT compatible
computer.
FOUNTAIN AT
*CUSTOMER REPORTS* that this 80286-based system is compatible with current
Above Boards and Matched Memory Classic. This computer is switchable
between 8 & 10MHz.
Tech Note: In at least one system, it was necessary to manually install
the Above Board 286 software, we have not had these reports with the Above
Board Plus, Plus 8, or Matched Memory Classic.
