Epson Equity LT

The Epson Equity LT 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 color 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.  The review unit came with one 3 1/2" floppy and the 20 MB hard disk.There's a real-time clock/calendar, and a 50-byte CMOS RAM forconfiguration purposes.  The LT runs on a 100/120 VAC, 200/240 VAC power supply (and battery charger), or 9.6 NiCad rechargeable battery pack.

The Epson includes MS-DOS 3.2, GW-BASIC, and a utilities disk, along with their usual excellent 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. Since the temperature operating range was listed at 41 to 95 degrees F, I didn't take it poolside, as it's well over 100 degrees outside at this writing. Storage range, however, is -4 up to 122 degrees F. Setup is no big deal.  Epson didn't opt for the 25-pin serial port, so be sure to have an AT-compatible (DB-9P) serial cable on hand or an adapter. 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. Depending upon your usage, you may not even have to change the back set of DIP switches.
