Some of these might have been printing errors, some may have been original program errors.
The original book is available online: And on Amazon:
However, we live in Internet time, and the Internet has enabled me to find books that I would never have been able to find formerly. The intent was to scan it in and OCR it (convert it automatically to computer readable text).
Unfortunately, the programs in the book had been reproduced from listings made on a dot matrix printer, and attempts to OCR it yielded nothing but garbage.
The gaming empire that became Quake started as a humble Apple computer game named "Castle Wolfenstein".However, I was able to obtain a collection of the programs in a archive file meant for CP/M users (probally for Microsoft Basic-80).In this collection I found most every file accounted for.If you got one, for the steep price of about 00, and then put it together, not a small feat, what you got was a big blue box with lights on the front. Next, a lit bit was walked across each of the front panel lights in turn, marquee style. These elementary Basic programs are still perhaps the only collection of programs that can honestly be said to run on any computer, anywhere.If you did your homework correctly, those lights did the right things, and after carefully reading the manual, and inputting several byte instructions, painstakingly flipping each bit of the byte, 8 bits, then hitting enter for each byte, you could actually get the machine to do something sensible with the lights on the front. Finally, the game "shoot the duck" was entered, which rotated a light across the row of lights. This property alone makes a museum collection worthwhile.
Thus, hopefully, the programs are titled with the proper authors.
