Subject says all. i need to know the names of the team that created the hp48s, along with the post each one of them had. Direct me to a page that has them, or give me that info directly at my email or with a reply to this post.

thank you, George Tsiros hp48gx@hol.gr gtsiros@yahoo.com

Try the command "RULES" on the 48; then you have the first names of everybody involved. And Diana (Byrns) is a nice person, I had a change to speak to her when she was in Amsterdam some 8 years ago.


Menno, I don't think the RULES command does anything on the S series. It's the G series that gives you the development team. As usual, www.hpcalc.org is the best resource.

There is a video that tours the new HP48SX calculator. Dr Wickes does the introduction. So, if someone is interested, get in touch with me.


As far I know "rules works also on the 48S-series, but I'm not sure.


You may find some full names on the Hewlett Packard Journal, some issues are online, and a search engine is available.

Try www.hp.com/hpj

The following articles (and, perhaps more useful to you, author names) were published on the June 1991 issue of the Hewlett Packard Journal:
