TSX-32

TSX-32 is a discontinued general purpose 32-bit multi-user multitasking operating system for the x86 architecture platform, with a command line user interface. It is compatible with some 16-bit DOS applications and supports the FAT16 and FAT32 file systems. It was developed by S&H Computer Systems, and has been available since 1989.

DEC-oriented columnist Kevin G. Barkes noted that TSX-32 is "not a port of the PDP-11 TSX-Plus" and that it runs well on 386, 486 and Pentium-based systems.^[1] He reported a limitation: since it supports the MS-DOS FAT file system, filenames are 8.3.
