What type of LCD does come with it? How large is it?
Q7.
A.
The LT-286e has an EGA - compatible paper white, backlit LCD; 640 x
350 resolution; 8 level gray scale. The active screen area is approximately
10.25 inches diagonally.
Q8.
Why do the specifications in the User's Guide indicate 640 x 480 pixel
resolution?
A.
That's the maximum resolution the hardware is capable of. The closest
compatible software video standard is the 640 x 350 pixel resolution of the
EGA standard.
Q9.
How can I use the memory between 640K and 1MB?
A.
This 384K block of memory can be used as extended memory (to use
VDISK outside of conventional memory, for example) or it can emulate
expanded (EMS) memory using the Turbo EMS software.
Options
Q10.
Can third - party option cards be installed in the LT- 286e?
A.
The LT- 286e has one 2/3 length internal 8/16 bit IBM AT- compatible
expansion slot for third - party option cards.
controllers or video display adapters, as these would conflict with the
internal circuitry.
Q11.
Can a math coprocessor be used? Is it user - installable?
A.
Yes, the Intel 80287 - 8. The coprocessor clockrate is fixed at 8 MHz.
Installing the 80287- 8 will increase the power requirements and decrease
the time of battery operation, though. Yes, the installation instructions are
in Appendix B of the User's Guide.
Q12.
The User's Guide references the 80C287 CMOS math coprocessor. Why?
A.
There were some changes in the design considerations for Intel's CMOS
version of the '287. These include additional power and ground signals that
are not standard for the NMOS '287, and were therefore not part of the
LT - 286e's basic design, Specifically, the 80C287A - 12 math coprocessor
SHOULD NOT be installed in the LT- 286e as component damage could
result.
