Re: HP41 models and susceptibility for cracked posts Message #2 Posted by John Robinson on 22 Mar 2010, 6:39 p.m., in response to message #1 by Nigel Bamber
Hi Nigel, all 41 calcs are susceptible to screw post breakage, but as you point out, single board versions don't rely on case pressure to keep the contact between several boards. Hence single bpard calcs remain operational even if the screw posts are broken.
All half nuts are single boards, except for the CX models, which have an extra piggy back board, but it doesn't rely on case pressure for good contact between the main board and the piggy back board.
HTH
Cheers,
John
