@Fliszt: J'approuve un déplacement vers le fil "G850" à 100%: je n'ai pas réfléchi assez avant de publier.

Hey Robert, The axact BD03 routine I have been using to check the registers and it always alters their content just have a go at writing a small assembly program that populates whatever values in the resgisters and then call BD03. You can even do a test of calling BD03 before your run your program j...

I have no complaints about the assembler and monitor of the PC-G850VS. The monitor shows the correct register values, but does not show the auxiliary registers. Perhaps you have an interrupt routine activated that alters registers before display? Registers ...

Hi G.E.
Thanks for the comments!
Sure, you can rewrite it and port the C code in any way you want. You have my permission.
Please post back on your progress. Happy to help if needed.

Hello Robert ! This is wonderful !! Reading your document at the moment, and will try on the real metal. Would you allow me to port it to the TI-89 (not knowing if it is feasible) ? It would display a copyright notice as appropriate, no commercial purpose, and I would send you the resulting code. Yo...

Hi,

I saw your thread 2 days ago on the hpmuseum forum (I'm not registered). That's great!

I'd like a LISP for RPL (hp-50g) to play with.
RPL an other weird language… or not.

Appreciation for Lisp grows over time

Lisp is interesting once you write an interpreter for it or studied the internals in its simplest, purest form. That's what this little project is about.

Otherwise, Lisp is just awkward syntax!
