Technology of the 1980s -- available here and now

 Classic.

Run classic games and legacy BASIC applications designed for MS-DOS
systems, IBM PC, PCjr or Tandy 1000.

 Faithful.

PC-BASIC aims for bug-for-bug compatibility with Microsoft GW-BASIC.
It runs ASCII, tokenised and protected BASIC programs and supports
the Microsoft Binary Format for full interchangeability of data
files.

 Versatile.

PC-BASIC supports GW-BASIC, BASICA, PCjr Cartridge BASIC and Tandy
1000 BASIC.

It runs on every platform that supports Python.

 Yours.

PC-BASIC is free & open source software, released under the GNU
General Public Licence version 3.

Compatibility

Graphics

MDPA, CGA, EGA, or VGA; PCjr or Tandy; or even Hercules or Olivetti
graphics - PC-BASIC can emulate all of them.

Music

Tandy and PCjr 3-voice music and noise generation are fully
supported. As are IBM PC beeps.

Printing

No helper programs or difficult settings needed: printing through
LPRINT and LPT1: works out of the box.

Comms

Full support for 2 serial ports included -- no matter whether they
are real serial ports or emulated through sockets.

---------------------------------------------------------------------

Convenience

Languages

PC-BASIC understands a large number of MS-DOS code pages and supports
all Unicode scripts natively. BASIC program in Chinese? Not a problem
for PC-BASIC.

Tapes

Have old IBM PC audio cassette recordings in WAV format? PC-BASIC
will open your files though its CAS1: device.

Scripting

Script a quick few lines of BASIC on the Unix or Windows command line
with PC-BASIC's command-line interface.

New Stuff

PC-BASIC is under active development and new features are implemented
regularly. Comments, requests and suggestions are always welcome!
