Epson LT - 286e - Manual (Page 12)

The 80C286 microprocessor inside your Equity LT-286e can
run at an execution speed of either 12 MHz or 8 MHz.
Ordinarily, you’ll want to use the 12 MHz speed to get faster
performance from your computer; a few application programs
may require the 8 MHz speed. A slide switch allows you to
change the speed.
The Equity LT-286e also has a built-in socket for an 80C287
math coprocessor, which you can easily install or have installed
by an authorized Epson dealer or Customer Care Center.
The built-in serial and parallel interfaces allow you to attach
almost any peripheral device, such as an Epson printer or
external modem, to your Equity LT-286e.
You can connect a color monitor to the computer to take
advantage of the color and the larger display. A slide switch lets
you change between the LCD and an external CRT display.
The LT-286e supports MDA, CGA, EGA, and extended EGA
video modes.
You can also connect an Epson external 5 diskette drive
to the computer to easily exchange data with other computers
that use 5 diskette drives.
The following optional equipment is available from your Epson
dealer:
An 80C287 math coprocessor
A 2400-baud, Hayes®-compatible, auto-dial internal modem
An internal RAM memory card to expand memory to 2MB
An external 1.2MB, 5 diskette drive
The GW-BASIC® programming language
An additional 20MB or 40MB hard disk drive
