The Epson Equity LT (model Q150A) weighs in at only 14.3 pounds, with the hard drive and supertwisted backlit LCD. Parallel and serial (9-pin) ports are standard, as is the colour monitor port. Two option slots house the hard drive and optional 300/1200 baud modem card. Measurements are 12.2" deep by 13.6" wide by 3.2" high.

Standard RAM is 640K; ROM is 16K. Epson uses the V30 microprocessor, with dual speed of 4.77 or 10 MHz. There's a real-time clock/calendar, and a 50-byte CMOS RAM for configuration purposes. The LT runs on a 100/120 VAC, 200/240 VAC power supply (and battery charger), or 9.6 NiCad rechargeable battery pack.

Epson includes MS-DOS 3.2, GW-BASIC, and a utilities disk, along with manuals. Although the keyboard has a soft, non-tactile touch, it was easy to type on nevertheless. The function keys are on top, and a standard numeric keypad is included in the 85 keys. The seven LEDs indicate POWER, LOW BAT, L & R DRIVE, CAPS, NUM and SCROLL. There are two sets of DIP switches, one on the upper right above the NumLock key and the other on the back panel. The set above controls the LCD screen, allowing you to select dark characters on a light background, or vice versa. To the left of the DIP switches are the reset and CPU speed switches.
