Editing MUMPS (section)

=== 1980s ===

During the early 1980s several vendors brought MUMPS-based platforms that met the ANSI standard to market. The most significant were:
* Digital Equipment Corporation with '''DSM''' (Digital Standard MUMPS). For the PDP-11 series DSM-11 was released 1977.  '''VAX DSM'''<ref>{{cite book |title=VAX-11 DSM Language Reference Manual |date=1982 |publisher=Digital Equipment Corporation |oclc=29217964 }}</ref> was sold in parallel after released 1978. Both hardware families as well as MUMPS versions were available until 1995 from DEC. The DSM-11 was ported to the [[DEC Alpha|Alpha]] in two variants: '''DSM for OpenVMS''', and as '''DSM for Ultrix'''.
* [[InterSystems]] with '''ISM''' (InterSystems M) on VMS (M/VX), ISM-11 later M/11+ on the PDP-11 platform (1978), M/PC on MS-DOS, M/DG on [[Data General]], M/VM on IBM VM/CMS, and M/UX on various Unixes.
* Greystone Technology Corporation founded 1980, with a compiled version called [[GT.M]] for AIX, HP-UX, UNIX and OpenVMS
* DataTree Inc. with an Intel PC-based product called '''DTM'''. (1982)
* Micronetics Design Corporation (1980) with a product line called '''MSM.''' MSM-PC, MSM/386, MS-UNIX, MSM-NT, MSM/VM [[operating system|fo IBM]],  VAX/VMS platforms and OpenVMS Alpha platforms.
* Computer Consultants (later renamed MGlobal), a [[Houston]]-based company originally created '''CCSM''' on 6800, then 6809, and eventually a port to the 68000, which later became '''MacMUMPS''', a [[Classic Mac OS|Mac OS]]-based product. They also worked on the '''MGM''' MUMPS implementation. MGlobal also ported their implementation to the DOS platform. MGlobal MUMPS was the first commercial MUMPS for the IBM PC and the only implementation for the classic Mac OS.
* [[Tandem Computers]] developed an implementation for their fault-tolerant computers.<ref>{{ cite web |url=https://techlibrary.hpe.com/docs/enterprise/servers/nonstop/SPML_20_January_2012_final.pdf | access-date = 2014-05-17 | title = HP NonStop Servers, Software Product Maintenance List, Effective Date: January 2012 | publisher = Hewlett-Packard Development Company, L.P. | date = 2012-01-20 | page = 32 }}</ref>
* [[IBM]] briefly sold a MUMPS implementation named '''MUMPS/VM''' which ran as a [[virtual machine]] on top of [[VM/370]].<ref>{{cite news|title=Two versions of MUMPS out|url=https://books.google.com/books?id=7RERQMhC7cYC&pg=PP23|date=1987-11-30|newspaper=Computerworld|volume=XXI|issue=48|access-date=2022-07-09}}</ref>

This period also saw considerable MDC activity. The second revision of the ANSI standard for MUMPS (X11.1-1984) was approved on November 15, 1984.
