No Spaces for You
I wasn’t sure in my last post how to remove the extra space from the program listings. Well, I figured it out. It was surprisingly easy and took me about five minutes of searching and updating. Apparently there is a CSS property called line-height. Set it to one and problem solved…

July's Program: Sugar Cube Munch
Another simple program. Like many that I wrote for the ZX81, Sugar Cube Munch was small with a singular purpose. In this case, the goal is to eat all the cubes of sugar as quickly as possible. Once all the sugar is eaten, the game is over and the number of turns is revealed…

Then use the 5, 6, 7, and 8 keys to move (left, down, up, right) just as they are on the ZX81 keyboard. Water Bug II was a …

Slow Going
I really meant to have a number of my programs converted this month. I found a tape player and have been trying to load my ZX81 programs off the original tapes; however, I keep running into a problems. I'm not sure if it is my microphone, the recording software, or my emulator…
