I played around a bit and it seems it is a software issue. I can change the brightness in first few moments after the machine starts booting and it stops working during the boot sequence. 🤷‍♂

Cool. May I ask, what materials did you use back then to learn to program it?

@@MacLegacyLabs Pascal was the ucsd version. the rest I really can't remember, but I'll look

@@davidlopanful Thank you a lot. If you find anything I could use as learning material I would be pleased. I have found some books, but I think it is somehow breach of the living memory of Macintosh programming. If I compare the written materials to what is being said in our lectures, there are so many tips and tricks which are not written in the official textbooks. And another thing is, I don’t even know with what book should I start and which should follow. Mostly they are focused on one topic, such as Game development, but I miss some sort of structured way how to proceed. Right now I am trying C because I have some previous experience and I think it is an easy entry point in getting familiar with the Toolbox, the programming IDEs of 90s and etc.

@@MacLegacyLabs MacC, Macforth, fortran77, assembly compiler I couldn't find but there was one.

macintosh Programmers workshop. Thats the assembly language, had to look it up

Hi. Thank you. Sure I will. I got some feedback from my friends, that the code in the video should have larger font, that I should parse the video into smaller chapters and also that the application is boring. :D Thus I decided to create a snake game. It shows the same principles, but the result is more satisfying. I have just tested it on a real hardware and I hope I will be able to record the video on Monday. Matouš
