Awesome work. This has to be one of the best Pi1541 setup video I have seen so far. For best compatibility it is best to disable the displaying of the IEC bus signals on the HDMI screen. This can be done by removing the line "GraphIEC = 1" or changing it to "GraphIEC = 0" in the options.txt file. It is not strictly necessary to do so my it can help improve compatibility. When developing I use it to see the signals but for general use, it can be advantageous to turn them off as this ensures the Pi has more cycles available to it to keep up with the real-time emulation requirements. Sorry, I should have made "GraphIEC = 0" the default option.
Hey, what a great comment to start the day with, thank you! And I want to thank you for all the work you've done on the hardware and software side to make such a great device. Great advice on disabling the IEC bus signal, although it does look good for demo purposes. I'm looking forward to playing with this some more and making a follow up video. 👍
Very nice. I did essentially the same build with a 3A+ a month ago, and I found the 1.24 kernel would not pass the most challenging test I found - Star Wars Demo from csdb - but the 1.23 firmware does. I also disable the graphical IEC display. The PiZero 2W also passes this test with a 1300 overclock, as it's basically the pi3 platform and uses the pi3 version of pi1541 as well. However, the original Zero does not seem to have the nutz to hang with the Star Wars Demo. It simply needs a bigger overclock than I can get it to accept, though I imagine it's fine for 99% of things at 1100 - 1150.
True, although I did manage to get the Pi 3A+ I used for this, a couple of weeks ago, for under £30. Hopefully, Raspberry Pi availability will improve soon bringing prices back down, making this a more viable proposition.

Presumably, you could make folders under the 1541 folder to allow some organization of disk images.

I love my Pi1541... well actually I have more than one 🙂 I built a couple of tebl Pi1541 variants (they look like a stack of small floppy disks).
With Pi prices retro 1541s are way cheaper.
