The makefile now works for Linux and most Unix's. However, for Solaris
and MacOS, you must first export the OSTYPE environment variable:
> export OSTYPE
> make
Otherwise, you will get build errors.

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
