DPS8M Simulator R3.1.0 Released!

The DPS8M Development Team is proud to present the latest stable version of DPS8M, the DPS‑8/M mainframe simulator: DPS8M Release 3.1.0.

DPS8M is a simulator of the 36‑bit GE Large Systems / Honeywell / Bull 600/6000‑series mainframe computers (Honeywell 6180, Honeywell Series‑60/Level‑68, and Honeywell/Bull DPS‑8/M), descended from the GE‑645 and engineered to support the Multics operating system.

DPS8M R3.1.0 adds a few new features, improves platform support, fixes many bugs, and offers greatly improved performance for most users.

The DPS8M Development Team recommends that users of older versions upgrade to R3.1.0 at their earliest convenience.
