DEC-oriented columnist Kevin G. Barkes noted that TSX-32 is "not a port 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 DOS's 8+3.

TSX-Plus

An earlier non-DEC operating system, also from S&H, was named TSX-Plus. Released in 1980, TSX-Plus was the successor to TSX, released in 1976.[2]

The strength of TSX-Plus is to simultaneously provide to multiple users the services of DEC's single-user RT-11. Depending on which PDP-11 model and the amount of memory, the system could support a minimum of 12 users[3] (14-18 users on a 2Mb 11/73, depending on workload).

History

S&H wrote the original TSX because "Spending $25K on a computer that could only support one user bugged" (founder Harry Sanders); the outcome was the initial four-user TSX in 1976.[3]

For TSX-32, they said in an interview,[3] "We started with a clean sheet of paper" rather than starting with a "port."

VAX

The company's product line was ported/expanded for the VAX line. [2]
