The third release of the HP 3000 Series III simulator is now available from the Computer History Simulation Project (SIMH) site:
https://github.com/simh/simh This release adds the cold dump facility. Entering the DUMP command simulates pressing the ENABLE and DUMP front panel buttons. The contents of main memory are written to an attached magnetic tape in a format suitable for analyzing with the DPAN4 program provided with MPE. The new SET CPU DUMPDEV and SET CPU DUMPCTL options specify the default device number and control byte for the dump. Also, the user may simulate a system power loss with the POWER FAIL command and resume powered operation with the POWER RESTORE command. The SET CPU ARS/NOARS command determines whether or not MPE automatically restarts when power is restored. The full set of new features is listed in the release notes that accompany the simulator source files. In addition, an updated HP 3000 Simulator User's Guide that covers the new commands is provided in Microsoft Word format with the source download and also as a PDF file at: http://alum.mit.edu/www/jdbryan/hp3000_doc.pdf The preconfigured MPE-V/R disc image available from Bitsavers: http://www.bitsavers.org/bits/HP/HP_3000/ ...was not changed for this release. -- Dave
