Will this work with the original parts I bought for both of us?

Yes.

Although, I did get the RP2040-GEEK to work, and it is less than half the price (only $16.31 from Amazon - https://www.amazon.com/RP2040-GEEK-Development-Raspberry-Microcontroller-Downloader/dp/B0CG82MKWC.) The only thing that would need to be added would be the micro SD Card.

This would also eliminate the need to wire the thing up (and also eliminate the possibility of mistakes in wiring.)

The only thing remaining for this is for me to figure out how to work with .DSK files so that I can remove the extraneous stuff, and add the editor and assembler/linker.

So, I am also continuing work on the RP2040-GEEK version, in addition to the original.
