Q39.

What are the differences in GW-BASIC 3.20 between the Equity LT

other desktop computers?

The version of GW-BASIC provided with the LT is the same version

supplied with the Equity + series PCs. However, due to the fundamental

differences between a desktop and a laptop PC, certain GW-BASIC

commands and functions do not apply to the LT. Specifically, the LT

doesn't support commands that control:

- Hercules and EGA

- A joystick

- A light pen

- Networking

- More than one parallel port

- An enhanced (101-key) keyboard

Q40.

What does the LIGHTON command do?

If you have set the backlight period, the EL element turns off after

the specified amount of time. Pressing any key calls the LT's ROM

BIOS keyboard routine, which re-activates the EL element. However, if

a keyboard driver (such as KEYBxx) is loaded, the BIOS keyboard

routine is bypassed. This can also occur with certain terminate-and-

stay-resident (TSR) programs. LIGHTON will trap the keystroke and

invoke the BIOS keyboard routine long enough to activate the EL

element, then return control to the driver or TSR. Be sure and load

LIGHTON after you load the driver or TSR; the order is very

important.

Q41.

Can I run OS/2 on my LT?

No. OS/2 requires a minimum of an 80286 CPU and 1.5 MB of RAM.

The LT uses an NEC V30 CPU, which is 8086-compatible, and provides

a maximum of 640 KB of RAM.

Q42.

I f a n a p p l i c a t i o n r e q u i r e s y o u t o s e l e c t

installation procedure, which choice should I make for the LT?

The LCD display of the LT emulates the CGA (Color Graphics Adapter)

standard. You should choose that option. Also, some applications let you

select "no color" or "single color" for the CGA implementation - this

may make the display easier to read, Finally, some applications (such as

Sidekick Plus) have an option like "Black and White (for Portables)". If

so, you should select this option.
