What "type" of contacts are on 71B Modules? Message #1 Posted by Mike on 8 Sept 2006, 8:03 p.m. The HP-71B has finger contacts that wipe on the circuit board, as a module is inserted. Anyone know what the "type" or "name" of those contacts are? Anyone know if it is still possible to get that type of contact or one that will work as well for 71B modules?

See for instance on my page here If you plan to rebuild HP-71 modules, maybe will you be able to find somebody able to make the contacts based on these schematics.
