2018年3月1日 · The connectivity kit of the HP 39gs I managed to install in windows 10 but does not recognize the calculator with the newRPL already installed.

2015年4月25日 · Awesome! Since HP-39gs was beaten by Ti calculators especially in the Chinese education market, millions of package-less unused unit came out as e-garbage, you can purchase as many as you want for only about 8~15$ per unit (including shipping in China) on taobao, this modification might be extremely useful!
