I wrote a program for the (unexpanded) Vic-20 that is based on the Micro Head Align program for the Commodore 64. I wrote this program because there are many of these kinds of programs for the Commodore 64 and none for the Vic-20. For example, on the Commodore 64 you can use the excellent HeadAlign…
There are times when it’s necessary for you to use the tape interface with your Commodore computer. For instance, some games on the Vic-20, like Adventure Land, require a tape drive for loading and saving games. If you use an emulator, this is not a problem since the tape device is also emulated, but if…

Why is this being delayed? Well, mainly because I just rediscovered my old Commodore 64 computer. This has led me down a rather long, but…
My love affair with coffee started one day (many years ago) when I drank a delicious café au lait in Bordeaux, France. After a few days of delicious treats and coffees, I was hooked for life! At the time, I was a lowly graduate student, and I was used to the standard fare that Canada…
Hola amigos y bienvenidos! My personal blog is up and I’m learning WordPress and web hosting as I go along. To be honest, it used to be much simpler to host a site in the old days (I haven’t looked into website development in ages), but today’s tech gives people more options to publish content…
