This adds the modifiers CONVERT and NOCOVERT to the HI units. When enabled for a unit, 1822 messages will transparently be converted. IMP-to-host messages are converted from the old, short (32-bit) format to the new, long (96-bit) format. Host-to-IMP messages are converted in the other direction. The motivation for this feature, is that the currently running IMP software is from 1974 and only supports short leaders. Some operating systems are from a later era, and only support long leaders.
Open SIMH machine simulator
This is the codebase of SIMH, a framework and collection of computer system simulators.
SIMH was created by Bob Supnik, originally at Digital Equipment Corporation, and extended by contributions of many other people. It is now an open source project, licensed under an MIT open source license (see LICENSE.txt for the specific wording). The project gatekeepers are the members of the SIMH Steering Group. We welcome and encourage contributions from all. Contributions will be covered by the project license.
The Open SIMH code base was taken from a code base maintained by Mark Pizzolato as of 12 May 2022. From that point onward there is no connection between that source and the Open SIMH code base. A detailed listing of features as of that point may be found in SIMH-V4-status.
