Sure, that's the 40 year old HP program with ..."mediocre" accuracy, especially in the distribution tails.

The program is the one linked to in this thread. Even in the message you quoted:
"As already mentioned in the thread with that program: ..."

This program is now available as a RPN-67 card. Willy has posted the respective link in his message a few posts above yours.

I posted this program last summer in the museum's HP65/67/97 software library. This program uses a higher order rational approximation with much better accuracy than the good old Hastings version, as quoted in Abramovitz & Stegun and used in several HP software pacs. The required nine coefficients for this improved program are supposed to be stored on a data card. This program and a matching data card are now available as a RPN-67 card on the RPN-67 webpage Willy already linked to (section "Math").

In the meantime Willy seems to have addressed the mentioned problems and the current download should contain a fixed version.
