HP-41 Unit Management System Message #1 Posted by Angel Martin on 13 Sept 2003, 3:29 a.m.
Here's an entry in the nostalgia department - though fun!
I'm currently working on an extended Unit Managemenr System ROM (UMS) for the 41, based on the implementation made on standard modules like the THERMAL, MACHINE, or PETROLEUM packs.
My goal is to also add electrical units, obviously missing on these above.
I started reverse-engineering the MCODE listings for the "SI-" function, but was wondering if someone has information on how this UMS was designed and implemented, so I can get a boost start with the project.
Any suggestions will be appreciated. Also, if the interest is there, we could have it available on line once finished.
