These demos in BASIC can be found in the **(under development, new)** OS/8 RK05 system packs in the `RKB0:` partition.

Many of them were ported to OS/8 BASIC by DEC employee, Kay R. Fisher.  Most were published in the DEC publication, *101 BASIC Computer Games*. That book describes itself as follows:

>It is the first collection of games all in BASIC, It is also the only collection that contains both a complete listing and a sample run of each game along with a descriptive write-up.

The first printing was in 1973.  A quite readable preserved version of the 1975 edition can be found online at: If a demo is from this book it is designated -101- instead of ----- below.  If the demo from the book, there will be a page or two of useful lore, and a sample run provided.

`BINGO .BA`    -101- Computer generates bingo card for you and itself and randomly calls out numbers at random.

`BLKJAC.BA`    -101- Play the card game of 21 against the computer.

`BLKJAK.BA`    -101- Version of Blackjack written for PDP-8 Edusystem 30 BASIC by Tom Kloos, Oregon MuseUm of Science and Industry.

`BUNNY .BA`    -101- Prints the playboy rabbit as typewriter art.

`CALNDR.BA`    -101- Perpetual calendar program, by Geoffrey Chase, OSB, Portsmouth Abbey School.  You must modify line 160 to name the day of the week for January 1 of your year.  (0 for Sunday, -1 for Monday, etc.).  You also need to modify lines 360 and 620 for leap years: Change the number 365 on line 360 to 366, and change the third element of the array in line 620 from 28 to 29.

`CHECKR.BA`    -101- Written by Alan J. Segal. Play checkers against the computer.

`CRAPS .BA`    -----  The dice game of craps.  Surprisingly it's not the version from *101 BASIC Computer Games*.

`DICE  .BA`    -101-  Simulates rolling of dice, and prints the distribution of values returned.

`FOOTBL.BA`    -101- The first of two football simulations found in *101 BASIC Computer Games*.

`FOTBAL.BA`    -101- The second of two football simulations found in *101 BASIC Computer Games*. Written by Raymond W. Miseyka, Butler Sr. High School, Butler, PA.

`GOLF  .BA`    -----  A not so great golf simulation.  The one in *101 BASIC Computer Games* looks a lot better.

`HELLO .BA`    -101- Simple conversation program where Petey P. Eight gives advice.

`HOCKEY.BA`    -101- Simulation of regulation hockey game.  Written by Charles Buttrey, Eaglebrook School, Deerfield, MA .

`KING  .BA`    -101- Land management simulation by James A. Storer, Lexington High School, Lexington, MA.
Missing a bit of the text output in the game published in the 1975 edition of *101 BASIC Computer Games*, but functionally equivalent.

`LIFE  .BA`    -101-  Conway's game of life, written in BASIC by Clark Baker, Project DELTA, Delaware School Auxilliary Association, Newport, Delaware.

`LIFE2 .BA`    -101-  Two players place pieces on the board and the rules of Conway's game of life determines who survies.  Written by Brian Wyvill, Bradford University, Bradford, Yorkshire, England.

`MONPLY.BA`    -101- Simulation of the board game, Monopoly, by David Barker, Southeastern State College, Durant, OK. Ported to OS/8 BASIC by Kay R. Fisher who eliminated the original RSTS-E virtual files.

`POKER .BA`    -101-  Play poker against the computer. Original author: A. Christopher Hall, Trinity College, Hartford, CT. Re-ported to OS/8 BASIC from [CPM Users Group source by Bill Cattey.  CPM User Group posting had missing bits, and a couple constructs OS/8 BASIC didn't like.

`ROCKET.BA`    -101-  Lunar lander simulation. Written by Jim Storer, Lexington High School.  Ported from Focal by David Ahl, Digital. Lost for a while due to bad disk bits.  Using a partial copy from [Dave Gesswein's a RSTS-11 version was found at and re-ported to OS/8 by Bill Cattey, converting RSTS BASIC constructs to OS/8 constructs, and eliminating some the ON ERROR GOTO stuff that was added to the RSTS version but does not exist in OS/8. This code diverged significantly from the version appearing in *101 BASIC Computer Games*, but is functionally equivalent.

`ROCKT1.BA`    -101-  Another Lunar Lander Simulator. Written by Eric Peters, Digital. Thought lost.  Recovered from [Dave Gesswein's

`ROULET.BA`    -----  European Roulette Wheel game.  Written by David Joslin.  Converted to BASIC-PLUS by David Ahl, Digital.  Ported to OS/8 BASIC By Kay R. Fisher, DEC.  Thought lost. Recoverdd from [Dave Gesswein's

`SIGNS .BA`    --  Program to print posters by Daniel R. Vernon, Butler High School, Butler PA.  When I tested the program under OS/8 BASIC I kept getting `SU  AT LINE 00261` which is a Subscript out of Bounds error.

`SNOOPY.BA`    -----  The old "Curse You Red Barron" Snoopy poster.

`SPACWR.BA`    -101-  Space war game based on classic Star Trek.  Game written by Mike Mayfield, Centerline Engineering.

`TICTAC.BA`    -----  Play tic-tac-toe with the computer.  Simple version.  Thought lost.  Recovered from [Dave Gesswein's

`WAR   .BA`    -101-  Play the game of war against the computer.  Was thought lost.  Recovered from [Dave Gesswein's Archive](). However, that port to OS/8 BASIC contained a bug and could never run.  Line 230 defines the array for the cards. In OS/8 BASIC the maximum string size needed to be specified, as well as the number of strings.  230 DIM A$(52,3),L(54) will not accomodate the 10-value card.  The 3 needed to be a 4.  Program fixed and run-tested.

`WAR2  .BA`    -101- Written by Bob Dores, Milton, MA. A battle with 72,000 soldiers you deploy to Army, Navy, and Air Force against the computer.

`WEKDAY.BA`    -101- Input a birth date and learn fun facts like how many years have been spent sleeping in the elapsed time.  Written by Tom Kloos, Oregon Museum of Science and 'Industry.

`WUMPUS.BA`    -----  Hunt the wumpus.

`YAHTZE.BA`    -101- Dice game of Yahtze.  Author unknown.  Quite an elaborate and comprehensive implementation.

Also on the `SYS:` partition is:

`RESEQ.BA`    ----- Re-sequence line numbers of a BASIC program.
