There have been a number of misunderstandings about the DPS8 GIT source code tree; sometimes leading to unfortunate user frustration.
The canonical usage of GIT generally has the master branch containing "releases"; they are expected to be "ready to go". Development takes place on branches; once the development branch is done, it is moved to the master branch as a release. The DPS8 emulator project is not following that model. With just a handful of developers, and any "release" being a hoped-for dream in the unimaginable future, the master branch is the bleeding-edge development code. Commit points on the master branch probably compile on the machine of the person making the commit, but there is no promise of functionality, portability, correctness, update procedures, testing or even that it will compile.
The Alpha 1.0 release was done as a tag on the master branch; this was poor planning on our part as it made it difficult to apply bug fixes to generate a 1.1 version. The Alpha 2.0 release is being done as a branch; this will allow bug fixes to be merged in from the master branch, enabling the creation of release candidates, and future 2.x releases.
As with the master branch please realize that there is no guarantee or implied understanding that release candidates are to work or able to perform any useful function. In this way you, our user community, will not by under any false assumptions about the quality of our release candidate distributions.
The DPS8M team would like to apologize for any difficulties our unorthodox and informal policies may have incurred.

Reverted to the previous version of rpv.reloaded.gz; apparently the new one
was not compatable with the Alpha 1 release.
Thu May 14, 2015
New rpv.reloaded.gz uploaded:
CMF updated to 16 HSLA lines.
FNP D enabled.
Sun Oct 19
Merged fault in to master.
Many fixes to IOM code: start of paged mode support, special status.
Sat Aug 30 19:45:48 PDT 2014
EIS code reworked. Now passes all 661 eis_tester tests.
Sun Jul 27 15:54:13 PDT 2014
Significent improvements to the code;
it now boots to 'bce (boot)'.
* Fixes to the interrupt system.
* Fixes to EIS instructions.
* Fixes to several missing or incomplete instructions.
* Working Disk system.
* Incomplete but functioning FXE.
* Rewrite of tarball creation script.
A new tarball has been created from the faults branch with these fixes.
Read the included RELEASE_NOTES.txt for instructions on booting.

More IOM haking ^H^H^H^H^H^H^H work.
Quoting CAC
“Okay, so deep investigation shows that IOM documentation is just wrong … I have long suspected the list service and indirect list service flowcharts in the IOM manual are generic reference models, and that each channel controller has its own unique algorithm for handling things. We are annoyed.”
eventually getting to….
CONSOLE: 1801.6 init_root_vols: Error reading dska_97a label. Unsupported label version
and a few small fixes for OS/X
Thu Jun 12 20:11:16 PDT 2014
Many changes and fixes. We're getting there. Kudos to Charles Anthony for making much progress towards implementing faults & exceptions.

Changes & Fixes
Updated as8 to accomodate alternate index/address register syntax where the register number is an operand.
Updated dps8 to include PL/I source-level tracing!
Various fixes generally caused by typos or sleepy typists :-)

Latest installment of simulator. Fixed undocumented feature in MVT. TALLY flag is apparently set along with the TRUNC flag.
Jan 31 21:47:56 PST 2014
Latest installment of simulator. Fixed a few bugs in the address register arithmetic instructions brought about by the rewrite.
Sun Jan 26 21:28:37 PST 2014
Fixed reimplemented address preparation code. Previously I was under the delusion that absolute mode never made use of the APU functions. Oh, how wrong and blind I was. ABSOLUTE mode now has the same access to APU functions as does APPEND mode.
Mon Jan 6 21:27:51 PST 2014
Rewrote/reimplemented address preparation code to handle R/M/W cycles and
operand sizes > 1 much better. Fixed undetected bug in ORSQ instruction.
Fri Dec 27 17:17:52 PST 2013
All sorts of updates & corrections both to as8 & dps8. Consult Wiki for latest ruminations
Beginning to start trying to run the Test & Diagnostics tape as well as the
Multics 12.5 boot tape. These are currently used to test the simulator and
neither run to completion or as intended - sadly. (Yet!)
20184: 1,093,571 Cycles
t4d_b.2: 31,184,718 Cycles
UnitTests: Pass
t4d/faults: 30,791,956 Cycles
Sat Nov 9 18:24:47 PST 2013
Adding code to detect illegal address modifications
Fri Nov 8 15:37:58 PST 2013
The new fault processing code broke some of the unit-test stuff. commented out some code until fault-processing
is completely implelemted. Will then regenerate some unit-test (TestEIS) code.
Thu Nov 7 14:44:27 PST 2013
Fixed bug in encoding of dfdi instruction. Added READ_YPAIR to flags.
Mon Nov 4 21:21:13 PST 2013
Enlarged input buffer to 2560 characters.
Fixed typo in as8.l ITP literal rule
Tue Oct 29 18:04:05 PDT 2013
Changed more operlapping strcpy()'s to memmove()'s. I understand why XCode5 (llvm) changed this behavior, but code that has
worked on at least 3 different architectures over the last 20-years should not break. That's what I get for not assuming
that my code would ever run under SMP when I wrote some of my utility routines in the early 90's. >sheesh<
Incorporated new unit-test for the Faux eXecution Environment. (The FXE is an attempt to create an execution environment for the simulator that is similiar to the standard Multics model. This makes testing of intersegment stuff much easier and allows for the creation and execution of a form of module not unlike Multics segments - although considerably simplified.)
Began testing of the XED instruction. Simple test cases seem to work. Needs further testing.
Mon Oct 28 20:28:43 PDT 2013
Removed calls to MMs fault/interrupt processing stuff.
Will be reimplemenmting for dps8m using homegrown code.
Fixed minor bug with XCode5 and overlapping string copies
Updated simh to latest version
Incorporated parts of Michael Mondy's Multics-emu project into my simulator
Therefore, portion of my simulator are ….

Beginning of unit testing framework
call/push/return seem to be functioning correctly. Just wish I knew when to use call vs. short_call etc. Little documentation on the practical differences between call & short_call just a few short descriptions in ALM docs. I know what the code does but why would you use one over the other and when?
Thu Jun 6 16:52:11 PDT 2013
short_call / short_return work in the FXE (Faux eXecution Environment.)
Tue May 14 19:45:44 PDT 2013
as8+: completed integration of Multics-style calling conventions. Assembler now generated meta info that *should* support the Multics execution environment's C/S/R API
Mon May 13 19:11:58 PDT 2013
Added Multics-style calling conventions to as8+; updated simh to latest v4.0-0beta
Sat Apr 20 20:14:37 PDT 2013
Added scaled, fixed-point literal support
Sat Feb 9 15:46:42 PST 2013
Added the 'decNumber' decimal arithmetic library to SVN.
