Hi all
Last week I was able to purchase (almost) a mint HP42S in one auction (21euros, not bad). I feel lucky now. I have had earlier his calculator but the first one was really worn out when recalculating my dissertation results. I remember that it cost 700 Finnish marks at that time (1990) which would be 175 euros today. Now I use this "second one" in my daily work.
My Q: what is the difference (if any) between HP 82240A infra red printer and its B version with HP42S?
best wishes, matti (Finland)
