[BE] From the source code of BECK0500: "The history of this version of Adventure has been lost, and I am unable to credit the originator. This program was converted to UCSD Pascal from a PL/1 version found on our local computer system. This version was obviously converted from a Fortran version (it said so in the comments) but any history was not indicated. ... Extended by Ted Beck. The changes to make the 500-point version were converted from a CDC CYBER 74 FORTRAN program written by Tony Jarrett and Paul Zemlin. It in turn was modified from an early DEC PDP-11 FORTRAN version of Adventure." Pending discovery of additional information, I am tentatively identifying the "PL/1 version ... converted from a Fortran version" with VMCM0350, as no other PL/1 version (save KFML0700) is currently known; and the "early DEC PDP-11 FORTRAN version" with WOOD0350. The game docs include a further note: "Some bugs fixed by George Schreyer", so some argument might be made that this should be designated SHCR0500. But unless a few bug fixes prove significant historically, there seems no real reason. Note that no dates are indicated in the docs.
[BH] At his web page Ravi describes BHCH0565 as a rewrite of a 565-pt Platt version, and BHAV0565 as a DOS port of BHCH0565. Conversely, the BHCH0565 docs describe it as a port of GOET0565. However, there is reason to doubt those accounts. First, there is no known Platt 565-pt version. Second, while BHAV0565 shares all the content of PLAT0550/GOET0550, the content it adds beyond those is altogether different from the extended content of GOET0565. It seems best, therefore, to surmise BHCH0565 descended independently either from PLAT0550 or from GOET0550 In private email conversation, Ravi has confirmed the existence of GOET0565 and that that BHAV0565 is an "exact repro[duction]" of it. He also says he has found the source code of his Windows version and will shortly make it available.

[GE] On 30 Oct '15 Gerrie posted a message in the comments section for Adventure over at IFDB: "For Retrochallenge 2015 I ported Will Crowther's original Colossal Cave "Adventure" source code to Microsoft Micro Color Basic. ... I re-coded the program from the Fortran source code and data file of Will Crowther's original version of 'Advent' for the PDP-10 recently recovered from an old back-up tape by Dennis Jerz. This is not the classic '350 point' version modified by Don Woods." The link was to a ZIP file which included an MC-10 (the TRS-80 MC-10 was a low-cost Tandy machine which sold briefly in the early '80s) emulator written apparently for Windows 95/98, but which still runs under Wine on Linux. To play, launch the emulator, type CLOAD, hit ENTER, then select File/Play cassette file... and navigate to cassette/JimG/COLOSSAL.C10. Then type RUN and hit ENTER.
[GI] Per Rick Adams' "A History of Adventure", "Jim Gillogly ... spent several weeks in 1976 porting" WOOD0350 "into C for UNIX. ... Gillogly later ported the code to Heathkit and then IBM-PC personal computers with the help of Walt Bilofsky." GIBI0375, then, seems clearly to be a child of GILL0350. See also the MOCAGH entry.
[GR] GRAY0375 was written for an adventure game system called Six/Fant, a system developed by Chris Gray himself, which ran on an IBM mainframe under VTMS. The author recalls in private emails working from a PL/1 source, which I am assuming was VMCM0350 because I am unaware of any other PL/1 version at the time. Though the source code bears a date of 1980, it clearly has borrowed additional material from GIBI0375, which was not released until 1982. More information is available on Gray's site.
[HA] "The History of Adventure" by "Ima Wimp", aka Doug McDonald. Regarding the ANON0551 controversy, O'Dwyer argues[OD1] the confusion stems from the assertion in HA that "The castle problem was added in late 1984 by an anonymous writer," which he considers simply a self-deprecating self-reference by McDonald. Others (e.g., [PA]) erred, O'Dwyer argues, in accepting McDonald's assertion at face value.
[HO] From an email from Wesley Holland to Arthur O'Dwyer, dated 15 May 2016: "I had a copy of ... Plotkin's 350-point version (PLOT0350)." Deciding to reimplement it in flash ("as an exercise to learn ActionScript"), he went looking for source code, and discovered WELL0550. " I pulled the descriptions from there ... making a handful of small changes along the way as necessary to conform with the 350-point map."

[JM] Not much is known about parentage or authorship. The game itself comes in a .hpi package, which apparently is a virtual floppy image for use with HPDrive and an ISA interface board which allows connecting a real HP 9845 computer to a Windows-based PC to utilize the PC as a mass storage device. This is not an emulator, but requires a working 9845. I have not located any HP 9845 emulators, let alone one that would load and run this image. Much further information is available at The HP 9845 Project website.

[MA] [OD1] (May 1, 2016) notes that MALM1000 has a "Software Den" identical to LETW0350's, and so supposes Malmberg drew it from that source. In an email of 24 May '16 he asserts, "MALM1000 definitely contains versions of all of GOET0580's innovations", while noting some of the GOET0580 material was imperfectly reproduced, speculating Malmberg may have been working from memory.
[MS] The instruction manual claims, "you have the complete version of the original Adventure. Nothing has been left out of the original DEC version." Filfre.net says it is "a slavishly faithful port of the original, minus only such PDP-centric niceties as 'cave hours,'", claims "the original’s external data file simply copied over to a TRS-80 floppy," and says "Microsoft Adventure is such a perfect clone of the original that it is now the ideal choice of anyone who wants to experience said original in as authentic a form as possible without building a whole virtual PDP-10... ." The in-game help screen says, "This is a complete version of the original M.I.T. * A D V E N T U R E *". Letwin made a few minor additions, the Software Den and two clues: Reading the Spelunker Today yields, "ADDRESSED TO WITT'S END", and to the description of "Breath-Taking View" is added, “WORDS OF FIRE, APPARENTLY HANGING IN AIR, SAY ‘PLOVER.'” See also Moby Games and The Internet Archive.

[RS] RASM0350 was an attempt to reproduce as authentically as possible the original Crowther and Woods version at a time when the original sources were still lost. It claims to be based on three versions, CALH0000, an "ISIS-II FORTRAN-77 version" based on WOOD0350 and BLKT0350, and "A FORTRAN version believed to be for a mini-computer (maybe Harris)" (see Moby Games). There is currently no known FORTRAN 77 port of BLKT0350; however, PLOT0350 is a FORTRAN 77 port of SUPN0350, a child of BLKT0350. The third source is completely unknown.
[RI] On 8/11/15 "Tom A" posted a query on rec.arts.int-fiction describing "an old game I played in the early 80's on a CDC NOS machine. Called ADVENTP, it was very similar to ADVENT (the original Adventure). The interesting thing was that it was written in Pascal... ." He had a hard copy of the source code, which read: "ADVENTURE IN PASCAL - MARCH 1979" and "WRITTEN BY GEORGE H. RICHMOND ... AND THE UNIVERSITY OF COLORADO COMPUTING CENTER". Another poster found corroborating evindence in the form of a letter by Richmond published the Sept. '79 issue of Pascal News: ""In my spare time, I have worked on ... a version of Adventure written in PASCAL. The original work was done on a CDC machine using the Release 2 Zurich compiler. Then I transported it to an IBM machine using our modified AAEC compiler. The IBM operating system is MVS with TSO."

[SB] Moby Games entry. Downloads of various Spectrum images are available here, where CRL Group PLC is listed as the publisher, and one Ian Ellery is listed as a co-auther along with St. Bride's School. Aside from the added graphics, this does not appear to be a very faithful implementation. The program introduces itself with, "Hi. I'm Trixie, spelunk me." And while you start in front of the well house building, the door is locked. "SCORE" command reports "You have £0,000 two shillings and fourpence three-farthings. A smart spelunker can make £131,000 in part 1." And the game is full of Britishisms such as "You jolly well can't." Per private email from John Elliot, this is intended as a parody.
[SU] The adv350kp.zip IF Archive download includes two archives. One, RT11SRC, is the source to SUPN0350 and contains ADVENT.DOC, which says, "This version of Adventure is based on two previous versions: A Fortran-10 version done by Willie Crowther and Don Woods. A Fortran-IV-Plus version done by Kent Blackett." These should be WOOD0350 and BLKT0350.
[UC] Mentioned in [D2]. Dalenberg provides more information in his 2009 rec.arts.int-fiction enquiry.

[?] Source of the information is unknown.
[VA] From a private email from Arthur O'Dwyer, dated 13 July 2016.
[VM] While source to a 350-pt VM/CMS PL/1 port was recently rediscovered and placed online, there is no certainty in identifying it with either Dalenberg's VMCM0350, or the PL/1 version mentioned in the credits for BECK0500. All three are presumed to be the same only because there is no information that any other PL/1 port existed at that early date. O'Dwyer also thinks this may be descended not directly from WOOD0350, but from one of the Fortran ports because, like them, it lacks both the cave hours and wizard mode.
[WI] Documentation included with the download of WITB0000. The History notes do not confirm [D2]'s claim that this was a port of JAEG0000. They begin in 1982 with Greg Huntzinger, who claims only to have corrected some spelling errors in some of the data files. Huntzinger doesn't specify his source is, so parentage is unknown. The JAEG0000 source is lost, so no comparison can be done. In 1985, Bob Withers ported the code to the Eco-88 compiler. That code is also apparently lost. In 1990 he ported the Eco-88 code to Microsoft C. Based on [D2]'s claim, then, I am positing JAEG0000 --> HUNT0000 --> WITH0000 --> WITB0000.
