Dear North Docota,
a virtual PPC Rom is also available for the EMU41 software emulator.
Today the PPC ROM is a nice part for collectors - and the belonging user manual (in the size of an heavey telephone book) is one of the greatest HP41 publications I know.
But for practical work today with the HP41, the later CCD Module gives you better performance and faster commands than the PPC ROM. The CCD Module includes synthetic programming and array functions and a lot of helpfully software tools.
PPC Rom is programmed by user language plus some synthetic. CCD is a complete mcode solution.
Raymond Del Tondo creates a extract of the CCD Module by removing the array functions (which also exist in the Advantage Module). Raymonds CCD Module version is called CCD OS/X and needs one 4KByte block. Also Angel Martin creates a own 8KByte version of the CCD Module.
By loading NOVRAM or CLONIX with PPC rom image files you are able to use the PPC or the CCD with your real handheld.
Because PPC and CCD are nice parts for collectors, their prices are really high - therefore using an emulator like V41 or EMU41 for learning something about this great modules would be a good first step solution.
In a later step using CLONIX or NVRAM would be possible with a lower price (and better HP41 plug in port configuration) than using the original modules for high prices....
