Musings and comments about our common interest
I have just received a copy of the PPC ROM and Manual for the HP 41c/cv/cx
While all ROMs enhance the function set of the HP41c series, there are several outstanding. So far, my preferred by far was the advantage PAC. It moved the HP41c to HP15c territory - but not quite.
The PPC ROM is an unassuming piece of hardware - identical to any other ROM. However, your opinion changes when you see the manual accompanying it. It has close to 500 pages (492 in my edition), and it is packed with all kind of functions. I have yet to go through it, but it looks as an early example of collaborative development -the sort that is giving us the likes of the wp34s and other open source software - but 30 years ago!
I am so excited with what I see that I would jump to conclusions too quickly. I have to go though the introduction pages (where I see names that appear very often in the HP museum forum) and get submerged in this great work.
As I am now travelling I can only read it - but this week end I will play with the hp41c, the ROM and the manual.
