step 1 for the BASIC zine would be to collect enough program listings

step 2 is typing them in myself to confirm the programs work, and also to provide digital copies of the programs

step 3 is collecting or writing some non-program listing articles. perhaps write ups on some kit computers or homebrew microcomputers

step 4 is to take the articles and format it into a document, published in print (PDF) and electronically (plain HTML)

*

step 1 is easy enough, having around 10 program listings would be ideal

step 2 is tedious, but not actually difficult, it will take the most time

step 3 will be the step that involves the most complexity. using articles by other authors will require navigating intellectual property concerns. writing original articles will take effort, but is not as complex as republishing others' work.

step 4 - trivial.
