Subroutine calls, now with RAM — 6502 part 7
Here's the next video in the series! If you already watched the longer video I posted a couple weeks ago, this is basically the last part of that, as I mentioned in the last post.
As always, let me know if you see any problems. I'm planning to release it tomorrow morning (Feb 29).
Thanks again for your support!

Thank you so much for this. I want to introduce my son of 5 Years to computer science and this is he best starting point ever! I’ve got everything working so far and as long as I use an Arduino as clock it works. But as soon as I hook up 1MHz the only thing I can see is the cursor... is this a timing problem?
I found on my version that I had to make a number of small changes to make it work at higher frequencies. Startup stopped working without a small delay to hold the reset low until power was stable and I also had to introduce either a busy-wait OR monitoring the busy line from the LCD to make the LCD behave correctly.
In the end you say: “Even six videos in, I’m not done […]”. Now that you split this video into two, you might want to change this to “even seven videos in”…
Excellent, top job.... thanks Ben ....
I see you fixed the "issue" between $00000001 and %00000001. This way looks better and creates no confusion. Another great one! Thanks, Ben!
