The version posted by Vince contains at least one error. It is hard to tell if this error was introduced in the original magazine article, in the book repeating them, in the original source, or in the transcription to this forum, but these sorts of minute changes can wreak havoc with the operation ...

Status to date. Working in extremely infrequent free minutes and slogging through the port. The version posted by Vince contains at least one error. In line 815 it contains G=0 however no other use of variable G. More suspiciously, the code paths in this section have several ways it can test the val...

I did some digging and it appears there are many different implementations, not all of which provide 30,000 bytes of data area. The language is not tightly specified and there are lots of undefined issues, among which are what happens if you step past the end of the data area, or how do you detect E...

Seemed straightforward, BUT

minor issue - uses exponentiation which is not supported in Apple I basic

major pain -- indexes arrays origin 0 (e.g. if you DIM A(5) they would access as A(0) thru A(4) which means lots of changes to both fixed references and loop boundaries

This is awesome -- thanks, Vince.

slowed slightly due to fuzzy resolution of book page and similar letters M, N, and H used throughout game. Need to understand the logic in order to choose correctly from indistinct blobs that could by any of the above.

Beginning port of game Awari, a Creative Computing title from the Basic Games book. It is an African game often played with beans or stones. The board is two rows of six pits which begin with three beans apiece. There are rules for moving the beans around the board, trying to get as many in your hom...

Due to the way it prints the maze and to the spacing for the prompt once it finishes, you can do a maximum length of 10 and still see the entire maze onscreen.

You can get up to 26 wide, and a 26 x 10 maze is decently big.

Here it is! This works pretty well, but it can be S-L-O-W for larger mazes. Doing a 20 x 20 takes about 2 minutes to complete, which seems much longer when you are staring at an unmoving screen. Also note that the length of 20 will not fit on one screen, thus without printers you can't see and enjoy...

This game will produce mazes with only one path from entry to exit. You select the length and width and it does the rest. A Creative Computing game from the Basic Games book.

Looks straightforward. Port started.

This one was very quick. no funny string manipulations, no read and data statements, pretty straightforward conversion. SCR LOMEM=768 HIMEM=16384 100 TAB(26):PRINT "COLUMN" 110 TAB(20):PRINT "CREATIVE COMPUTING" 120 TAB(18):PRINT "MORRISTOWN, NEW JERS...

I am porting the game Columns from the More Basic Games book. This is a card trick game. Some cards are dealt into three columns. You secretly pick a card, then tell the program the column where you see your card. It deals them out two more times in different arrangements, where you again say only w...

Well, I went ahead and finished it. It will scroll up to hide the previous guesses, which works fine on the video-only Replica/I (Apple/I) so the backspace and strikeover stuff wasn't needed. I did some cleanup of the program and added an 'out' if you get bored. Give it a whirl. There are strategies...

It is a broken and tedious game. Only discovered this now that I have it working partially. It has many flaws -- e.g. places where it accepts a card number from 1 to 52 but the error checking is X>0 AND X<52 which rejects one of the valid inputs. It rates the results and jumps to a set of labels (po...

Will attempt a port of Concentration, from More Basic Games book, another game from Creative Computing. The game is sometimes called Memory. This particular game depends on overstriking characters on the screen so it will require some ingenuity on the Replica/I. I believe that Vince put some special...
