MCODE - Hyperlinked SDK41 Manual



I recently started to read more about MCODE on the 41 and very soon this means coming across Warren Furlow's fantastic SDK41 package. It provides a great environment to create and test MCODE, build custom ROMS, single-step as well as full run through MCODE programs and see all registers etc. As you might be able to tell, I'm a great fan of it (albeit a primitive beginner)

While reading through the .txt manual I started reformatting some pages,created some graphs to represent the file-system etc. Soon one thing led to another and so now I have a fully hyperlinked word-formatted pdfed manual with color pictures strewn in for good measure. It really helps me locate information quickly.

Last but not least, I added a final section which is a step-by-step example on how to create a MCODE source file, assemble, link it, load it into the emulator and single step it, and then build a ROM image from more than one MCODE file in different notations. All with source code listings each step of the way. These basically were the steps that I went through to get to know the package, so I thought it might be useful for others as well.

I'm not sure to what extent there will be an interest from others for this file but I wanted to make it available. However I do not know a good place to host the pdf so that people can download it. So if anyone has a good suggestion on where such a file could be hosted, I'd be all ear (it would also help with other things to know such a place)




Hi, Peter

Good job. Send it to Warren. I think, the best place is in his web.


Hello Peter,

Good job. The obvious place is of course TOS. I will also glady put a copy on my website.



Dear Peter,

nice and really helpfully documentation for the HP41 world :-) Please send me the pdf document

best regards - Christoph Klug





Thanks Peter,

It is now hosted on my website here



Just a question???? What is the meaning of TOS??

In the Warren´s web you can see his mail. In the "Contact" menu.


Hi Peter,

Certainly TOS is the place for this.

Anyhow, I still have to make some updates in my website, can also host your files for downloading there... as a "back-up" resource, if you're happy with this idea.







Ok, I just can't wait until someone puts it up on a site. Could you send a copy to me?


Please send a copy to me as well. Thanks in advance.





Hi Peter, all...

Your document is now hosted at under a NEW! chapter. Please let me know if you find it adecaute.

Best wishes.
