It's great when the KZbin algorithm recommends interesting and novel content. One day I plan to do something similar: building my own system and programming it from scratch in assembly.

[@kosamika]

bravo sir. I managed to pull a signal with my oscilloscope from a z80 before i surrender. unlike mine, your determination has no limits. your work is epic, sir. congrats.

hello Denis, liked your project and your channel. thanks to algorithm for its suggestion.

[@blvckbytes7329]

I'm impressed by the fact that you have been working on your project for such a long time; that perseverance really is admirable! It would be awesome if you could do some walkthroughs, where you show off chunks of the system at a time and talk about how programs and hardware interact on your machine.

[@dennisgunia]

Thanks. I was also surprised when I realized how long I‘ve been working on that project. However I had to take some pauses on this project during that time to avoid burning out on it and loosing interest. I guess this is the key. I already recorded two much longer versions before this one that were over 90 minutes long and much more detailed. I decided to publish this shorter version and I will record more detailed episodes in the futere. In those, I will go more into detail regarding the individual components.

@@dennisgunia I really need to get into the habit of taking breaks too... So many projects have been ruined by burnout and my negative attitude towards them afterwards. It's a true art, haha! :)

[@TheMito97]

This is the coolest thing the algorithm has suggested to me in a while :) Keep it up, I’m looking forward to the next video :)

[@kosamika]

i can only agree 👍

Excellent work and great description. Thanks.

Great work! Happy I stumbled upon this, subbed.

If you need help with CP/M, I'd be happy to help. The whole time while watching this video I was thinking: "I have to ask if he's going to get CP/M onto it. I started learning Z80 assembly about 1.5 years ago on John Winans Z80 board. He has a whole series on his channel at John's Basement, where he goes through all the CP/M BIOS implementation and all that.

[@dennisgunia]

That‘s great! Thanks. I`ll check John‘s basement out and my come back to your offer! CP/M would be awesome and enable many more use cases.

[@TSteffi]

@@dennisgunia I have personally written two BIOSes for CP/M 3 by now. But that really only makes sense if you have more than 64k of RAM. And a BIOS for CP/M 2.2 is really not that difficult. You already have all the parts needed for it.

@@dennisgunia Are you in John's Basement discord?

[@dennisgunia]

@@andyhu9542Now I am! Still have to check out his channel though
