Correct (unless it's for the experiment I mentioned). However, the RAM limitation doesn't go away. You still have 264Kb and some of that will be needed for the control system, whatever that proves to be (for buffers etc. that can't use flash). You can't use flash for a frame buffer either and without a frame buffer your graphic options are limited! The RP2040 doesn't make a very good GPU. 640x480 with 64 colours leaving you with 39Kb of RAM to do everything else in. It may be doable in C, but such a display isn't going to set the world alight when a minimum spec RPi can do so much more.
On an entirely different subject, have a look at the Hantek 6022BL oscilloscope, Tom. My brother has one. They are very basic, but work remarkably well for audio frequencies (they are 20MHz / 48MS/s). The BL version includes a very crude logic analyser. There is a BE version that doesn't and costs a little less. Available from Amazon and AliExpress (about 55UKP from there incl. carriage). Don't need much bench space either.
