I had a few hundred copies of the map printed up, and I made cardboard counters using blank counters and rub-on numerals. I copied cassette tapes on my PET and labeled them by hand. I typed up a manual and had it photocopied. For the cover I drew a cute little picture of a PET with tank treads and a cannon emerging from its screen. The PET was so big and bulky that the rendition looked pretty good. I can't draw, but I can use a ruler and compass, which were all I needed for this simple line drawing. I folded the 34×22" map into quarters, and stuffed everything into a Zip-Lock bag. That's how software was made in the late 1970s.
For marketing, I prepared my own ad (see Figure 13.4).
