Notes For V3.9 The makefile now works for all *nix platforms and with cygwin and MinGW32 on Windows. 1. New Features 1.1 3.9-0 1.1.1 SCP and libraries - added *nix READLINE support (Mark Pizzolato) - added "SHOW SHOW" and "SHOW SHOW" commands (Mark Pizzolato) - added support for BREAK key on Windows (Mark Pizzolato) 1.1.2 PDP-8 - floating point processor is now enabled 1.1.3 IA64 VMS Ethernet Support - Identified compiler version issues and added IA64 support (Matt Burke) 2. Bugs Fixed Please see the revision history on http://simh.trailing-edge.com or in the source module sim_rev.h. 3. Status Report This is the last release of SimH for which I will be sole editor. After this release, the source is moving to a public repository: under the general editorship of Dave Hittner and Mark Pizzolato. The status of the individual simulators is as follows: 3.1 PDP-1 Stable and working; runs available software. 3.2 PDP-4/7/9/15 Stable and working; runs available software. 3.3 PDP-8 Stable and working; runs available software. 3.4 PDP-10 [KS-10 only] Stable and working; runs available software. 3.5 PDP-11 Stable and working; runs available system software. The emulation of individual models has numerous errors of detail, which prevents many diagnostics from running correctly. 3.6 VAX-11/780 Stable and working; runs available software. 3.7 MicroVAX 3900 (VAX) Stable and working; runs available software. Thanks to the kind generosity of Camiel Vanderhoeven, this simulator has been verified with AXE, the VAX architectural exerciser. 3.8 Nova Stable and working; runs available software. 3.9 Eclipse Stable and working, but not really supported. There is no Eclipse-specific software available under a hobbyist license. 3.10 Interdata 16b Stable and working, but no software for it has been found, other than diagnostics. 3.11 Interdata 32b Stable and working; runs 32b UNIX and diagnostics. 3.12 IBM 1401 Stable and working; runs available software. 3.13 IBM 1620 Hand debug only. No software for it has been found or tested. 3.14 IBM 7094 Stable and working as a stock system; runs IBSYS. The CTSS extensions have not been debugged. 3.15 IBM S/3 Stable and working, but not really supported. Runs available software. 3.16 IBM 1130 Stable and working; runs available software. Supported and edited by Brian Knittel. 3.17 HP 2100/1000 Stable and working; runs available software. Supported and edited by Dave Bryan. 3.18 Honeywell 316/516 Stable and working; runs available software. 3.19 GRI-909/99 Hand debug only. No software for it has been found or tested. 3.20 SDS-940 Hand debug only, and a few diagnostics. 3.21 LGP-30 Unfinished; hand debug only. Does not run available software, probably due to my misunderstanding of the LGP-30 operational procedures. 3.22 Altair (original 8080 version) Stable and working, but not really supported. Runs available software. 3.23 AltairZ80 (Z80 version) Stable and working; runs available software. Supported and edited by Peter Schorn. 3.24 SWTP 6800 Stable and working; runs available software. Supported and edited by Bill Beech 3.25 Sigma 32b Incomplete; more work is needed on the peripherals for accuracy. 3.26 Alpha Incomplete; essentially just an EV-5 (21164) chip emulator. 4. Suggestions for Future Work 4.1 General Structure - Multi-threading, to allow true concurrency between SCP and the simulator - Graphics device support, particularly for the PDP-1 and PDP-11 4.2 Current Simulators - PDP-1 graphics, to run Space War - PDP-11 GT40 graphics, to run Lunar Lander - PDP-15 MUMPS-15 - Interdata native OS debug, both 16b and 32b - SDS 940 timesharing operating system debug - IBM 7094 CTSS feature debug and operating system debug - IBM 1620 debug and software - GRI-909 software - Sigma 32b completion and debug - LGP-30 debug 4.3 Possible Future Simulators - Data General MV8000 (if a hobbyist license can be obtained for AOS) - Alpha simulator - HP 3000 (16b) simulator with MPE
