<DOWNLOADS>PRIME>EMULATOR


These files are related to the 50-Series software emulator written by Jim Wilcoxson.

Jim's software emulates a minicomputer architecture sold by Prime Computer from the early 70s through about 1993. Prime's initial business plan was to make systems compatible with the Honeywell x16 family, which had then-recently been discontinued. Prime extended the architecture heavily.

Development began in 2005. The emulator originally ran on the PowerPC architecture. In late 2011, Jim ported it so it would run on x86. This entailed solving endianness issues (The 50-Series is big-endian), as well as re-optimizing the code for performance without the host processor having a large set of general-purpose registers.

The emulator itself is available in source code form from github.
