[Simh] Release of a set of simulators for IBM 7000 series mainframes.

[Richard Cornwell]

I am pleased to announce the release of a set of simulators for IBM
7000 series mainframes. This includes simulators for the IBM 701, IBM
702, IBM 704, IBM 705, IBM 705/3, IBM 709, IBM 1410/IBM 7010, IBM 7070,
IBM 7080, IBM 7090 and IBM7094. These are available from the Computer
History Simulation Project (SIMH) site:

  https://github.com/simh/simh

Software for these simulators can be found at:

  http://sky-visions.com/ibm

Currently there is the following available:

  IBM 705: Some stand alone programs.
  IBM 7080: Diagnostics.
  IBM 1410/7010: PR 155 & PR108.
  IBM 704: SAP (assembler) and soon Fortran II.
  IBM 709: Lisp 1.5, 9AP (assembler), Diagnostics
  IBM 7090/7094: IBSYS and CTSS. 

  CTSS sources and binaries are available at:

  https://github.com/rcornwell/ctss

I am still working on an automatic rebuild of CTSS using IBSYS to build the 
basic binaries. However prebuild disk images are available.

These simulators have been developed over many years and I have way too many 
people to thank for the help that they have given in testing and recovery 
of software. Some of these simulators are more stable then others, the more 
software that I have to test them the more stable they are. The IBM 701 and
IBM 7070 are fairly untested since there is almost no software for either 
of these machines. These machines all shared a common set of I/O devices so
it made sense to implement them as a collection.

I plan to add in a IBM 7030 simulator after I finish transcribing and proofing
the diagnostics and MCP and write a assembler for the machine.

I would also like to do a 7040/4 if anyone can find a copy of either IBSYS
or DCSYS for it.
