Learning to input programs on HP-41

My original idea was to take advantage of the larger screen of the DM41X to display a binary, octal, hex, decimal representation of a number entered. Designated keys on the user keyboard would be used to specify the 'from' base and call the correct bits of code to set register 6 for the PPC ROM 'BD' and 'DB' functions. I downloaded the PPC ROM but alas my DM41X does not like any of the 6 micro-USB cables I have on hand, so I was not able to transfer the ROM, thus trying to type it in. New USB cable others have suggested should arrive today.

In the meantime, I can occupy myself doing more reading from Sylvain's suggestions and trying some other smaller ideas.

The shape of the DM4x models can sometimes interfere with the micro-USB connector making sufficiently deep connection. On some cables, you can simply shave some plastic from the the head shell around the connector, and this may allow deeper insertion. Another approach is to use a micro-USB cable with an extra-long tip, which sounds rare and expensive, but amazon has them for < $&:

It's well worth sorting out as the power of the 41X is scant until you load some of the hundreds of 41 ROM modules. Once you get basic 41 operations down, look at Angel Martin's AMC-OSX ROM, which adds many OS enhancements that make using the 41 easier.
