Microsoft Basic (5-9-1984) for the TI Professional Computer Released in 1984 by Texas Instruments ONLY for the Texas Instruments Professional Computer running MS-DOS Image quality: Unmodified/no write notch This is a special version of Microsoft Basic specifically tailored for the Texas Instrument Professional Computer. Unlike most Microsoft BASIC interpreters, TI did not bundle it with their MS-DOS, but sold it as a separate product instead. The TI Professional Computer was a non IBM hardware compatible x86 machine that ran a special adaptation of MS-DOS. As a result, this adaptation of MS-BASIC is also not 100% compatible with BASIC programs written for IBM PC. Important: This software will not run on an IBM PC or compatible. It will only run on a TI Professional Computer. Important: There was some damage on the disk, the kryoflux and SCP images will not create usable disk images. Please use the IMG or IMD copies instead. Archive includes one 5.25" 160k (8-sector single sided) floppy disk image. Note: This disk image uses a sector interleave of 2.
