The machine below is an IBM PC XT (Model 5160) with a 4.77Mhz 8088, 640K of memory, a Color Display, two diskette drives, and a 10Mb hard disk. It boots the BASICDOS-360K-D40 diskette and runs two 40-column sessions side by side; use SHIFT-TAB to toggle focus. Since the machine has a hard disk, the boot sector first displays Press a key to start...; press any key (or wait 5 seconds) to boot from the diskette, or press Esc to boot from the hard disk instead.
This demo is also available on an IBM PC, an IBM PC AT, and a COMPAQ DeskPro 386.
The BASICDOS-360K-D40 diskette’s CONFIG.SYS defines two 40-column consoles side by side, each running its own copy of COMMAND.COM. The left session runs HELLO.BAT, a batch file that displays a colorful greeting, while the right session runs PIPES.BAT, which pipes the output of DIR through the CASE filter over and over (press CTRL-C in that session to stop it).
Both sessions are configured with borders, and a double-wide border indicates which session has keyboard focus. Use SHIFT-TAB to toggle focus.
