Unidentified HP-41 PACs

[rprosperi]

"1C" means the 3rd release of Finance Pac 1. No other Finance Pacs were ever released by HP for the 41.

The best database, by far, of 41 ROMs is Matthias Wehrli's excellent list available at the following site:

In the case of your 2 3rd-party ROMs, 'PKSH' is there, but there is little detail about it, and the other one is not listed at all.

Congrats on finding some new and rare modules!

Hopefully, if you know how and have the right tools, you'd be willing to share ROM images with the community.

Most often, new and undocumented ROMs are from the Surveying or Forestry areas, but finding them in a machine along with a Finance ROM makes this seem less likely.
