PC2 Release History - pc2ccs/pc2v9 GitHub Wiki
This page documents the release history of PC² going all the way back to Version 1.0. It is mostly accurate.
September: Mary Richmond, Dave Bosley, Paul Meyers, and some other guy named Doug Lane make the mistake of accepting a Senior Project called PC2 under the sponsorship of John Clevenger, a Senior Project Instructor at California State University, Sacramento. That Lane guy still has no clue. Bliss is ignorance.
April: Version 1.0 (Turbo Pascal) is used for CSUS Spring Local Contest.
September: Mary, Dave, and Doug start "Special Project" to enhance the system to support multiple sites.
October: CSUS Local Contest used to test Version 2.? with "red & green" sites. John and Dave travel to Portland to check out UP site for Regional
November: Version 2.? used to run Pacific Regional at CSUS and University of Portland. Dave at Portland site. Remote site updates via ProComm/Kermit.
February: Version 2.? used to run Contest Finals in Washington, D.C. John detained by White House security (really).
October: Version 3.? used to run CSUS local contest
October: John and Doug visit Ellensburg, WA (always good to be upwind).
November: Version 3.2 used to run Pacific Regionals at CSU,Stanislaus and Central Washington University. Doug at CWU.
March: Version 3.2 described and distributed in a presentation to Regional Contest Director's Workshop at Contest Finals in San Antonio (Unix-based environment used for Finals).
April: Version 3.? used in CSUS Spring Local Contest
September: Eric LaMar and Richard Cuny start "Multi-Site Extension" Senior Project.
October: Version 3.? used in CSUS Fall Local Contest

November: Version 3.? used in Pacific Regional Contest at UOP (Stockton) and PLU (Tacoma)
April: Version ?.? with MSE used in CSUS Spring Local, with Red, Blue, and Green sites
October: Version ?.? used in CSUS Fall Local Contest, with Red/Blue sites
November: Doug and John travel to Ohio to run the East Central Regional Contest, using Version ?.? with Red, Green, and Blue sites. Still strictly floppy-based
November: Version ?.? used in Pacific Regional Contest at Cal State Chico and Western Washington University (Doug went to Bellingham). Still floppy-only.
October: CSUS Fall Local Contest is run using Version 4.?, still floppy-only. First ever attempt to reuse exactly the same bitset to run a contest fails due to Lab Virus.
November: unknown person "Sam Ashoo" arrives at John's office with the foolish request to have a copy of PC2 to look at. John foolishly agrees and give him version ?.? (floppy-mode only).
November: Pacific Regional Contest at CSU,Fresno and University of Oregon (Eugene). Doug at UO; Sam at Fresno. Used version ?.? (floppy-only); used Borland tools.
December: we were asked to provide software for the Finals to be held in Phoenix in March 1994.
January/February 1994 -- Randy Kath, Mark Measures, Dave Brennan, Dick Rinewalt, and Jo Perry came to Sacramento; we worked on some updates to 4.1, mostly on getting it to work with NT/AS. Doug came to Sacramento from Phoenix. We came up with Version "4.2A", which was still floppy-based, but "almost" worked with the LAN. Shortly after everybody left we fixed the last problem with LAN mode, and called it "4.2B".
March 1994 -- Finals in Phoenix. I spent a long time trying to convince Mark to go with 4.2B (LAN), but he wouldn't budge. We used 4.2A, with floppies, even though the LAN was in place and was used for clarifications (using Microsoft email stuff).
September 1994 -- we must have either done additional updates, or at least renumbered 4.2B to 4.3.
October 1994 -- John wrote a complete set of documentation (Administrator's Guide, Installation and Operation Guide) for Version 4.3.
November 1994 -- Version 4.? used for CSUS Fall Local.
November 1994 -- Version 4.? used at Pacific Regional at UW and USF. Doug and John at UW; Sam and Rob at USF.
January -- Testing in Sacramento
March -- Version 4.5 used in Nashville for Finals. Windows-based Team module, but Master/Judge/Scoreboard old Pascal Version.
April -- Sam provides "Version 4.5B". Slightly different from 4.5 used in Nashville.
June -- Development of Windows-based system starts.
Fall -- Troy Boudreau spends so much time hanging around, he is made official 'tester'. Proves to be a mistake; he's too good at finding bugs.
October -- PC2/Windows hobbles through local contest.
November -- Small UFO's contact PC2, claim they are friendly.
March -- Version 6.1 used to run Finals in Philadelphia. COLD! Code wrote funny little messages to our love slaves.
November -- Version 6.2 used for Pacific Regional and Mountain Regional.
March 1997 -- Version 6.3, Finals in San Jose, other than the bomb threat things went ok. Got those neat laser pointers.
Fall 1997 -- Tammy Torok makes mistake of asking John if he has any Masters projects available. Carefully making sure she cannot talk to Sam or Doug, John describes the concept of a platform-independent, Internet-based contest system. Tammy starts coding a prototype. Sam and Doug eventually warn her, but it's too late.
November 1997 -- Version 6.33 Pacific Regionals in Chico and Spokane WA. Discovered some very strange timing bugs.
March 1998 -- Fixed the timing bugs, but never created a new release number; reverted in fact to 6.3. Posted 6.3 on the Web; froze that as the last Windows-based version. Finals in Atlanta GA, cool cars we raced around in..
May 1998 -- Tammy demonstrates working prototype to John.
June 1998 -- Team meeting in which Sam, Doug, and Troy agree to look over prototype code.
September 1998 -- Sam, Doug, and Troy actually DO look over code, start in earnest on development of a complete system based on the prototype. Tammy finishes Master's Degree, makes mistake and accepts invitation to continue working on the project.
October 1998 -- Debut of PC^2 Version 7.0 (Beta) at CSUS Local Contest. Amazingly, it survives quite nicely!
November 1998 -- Version 7 Beta3 used to run South Central Regional in Houston (Rice University). System has performance lag which causes problems in Practice Contest, but does well in Real Contest. Other issues related to that particular contest best left undocumented... Later November -- Version 7 Beta 3, used to run Pacific Regionals at CSU, Chico and up north somewhere.
March 1999 - Version 7.1a (aka beta4 3/18) used to run CSUS Spring Programming Contest, works marvelously.
April 1999 - (Finals) Eindhoven The Netherlands, TUE, Arrived with 7.1a (3/18), used 7.1d used in contest due to new requirements from judges. Practice contest (aka stress test) shows some system/server (PC^2) load issues. Real contest works well, slows down at the end but some "stalls" are attributed to PC² server load. Another success.
Summer 1999 - Version 7.2 prepared for release. 7.1 stalls no longer happen. Supporting Unix and using Java Swing interface.
November 1999 - Mid-Atlantic Regional - Virginia Tech Version 7.3 (10/19) Complete Unix Contest, FreeBSD and Solaris. All went well except one site, which had just bad karma (and poor support). Supported 8 sites with 144 teams.
November 13, 1999 - Pacific Regional - Chico CA Version 7.3 (10/19). During the practice contest, lost complete power to judge's area. Recovered beautifully (once there was power). Within 1 hour of end of the contest, judging done, standings verified, all done - just terrific.
March 17, 2000 - Version 7.4 released on web site.
March 2000 - Finals in Orlando Florida, Version 7.4 (03/18 #3). Supported both the Finals and a site in Europe (TUE) for a team that could not get to Orlando. Went very well, small glitch found but within 5 minutes there was a workaround in place, code fixed.
April 2000 - High School Contest at CSUS - Version 7.4 (3/18 #3). Went very well.
November 12, 2000 - Pacific Regional - Spokane WA Version 7.5 patch 3. Very cold (brr, high of 32), snow. Minor setup issues (not with PC², but with things like compiler PATHs). Contest went just fine.
February 9, 2001 - Version 7.6
February 2001 - DeVry University, Fremont, local contest. Excellent setup and people. Contest went nearly perfect.
