What software is built into the 100/200LX ROM?
MS-DOS 5.0, Lotus 1-2-3 release 2.4, an appointment manager (capable of waking the 100/200LX up and sounding an alarm or running a program even when the machine is turned off), a calculator (similar to HP19B, capable of algebraic or RPN), a text editor, a phone book, a stopwatch/alarm clock, a world time database, a terminal emulator (but the 100LX version is too slow to use above 1200 baud, you’ll want a different communications program for a fast modem), a general purpose database, a note taker, a file manager, a keyboard macro editor, and cc:Mail. Note that, although MS-DOS 5.0 is built into ROM, not all of the external commands (e.g QBASIC.EXE, EDIT.COM, ANSI.SYS) are included. These may be copied from a PC running MS-DOS 5.0 (Caution: copying parts of DOS is probably illegal and/or a violation of your license agreement unless you buy a DOS license for your 100/200LX). The 200LX contains Pocket Quicken and LapLink Remote, in addition to the above.
