Rare findings season is opened!
Hi all,

Seems that a number of rare items are unexpectedly sowing up in the last few weeks.

First it was the STO. DOMINGO module:


Then the earliest (so far) pre-production HP-41C with its unique unreleased OS:


And now, the "Fish Population Dynamics" plug-in module for the HP-41CV:

Here... Just the manual, I'm affraid.

Does anyone has any info/knowlegde about this rarity? (Or have the real thing?)

More often someone come across a new rare module but, alas, no documentation. In this case the manual is available but the module isn't.

The range of applications for our beloved 41's is becoming wider and wider even though these ladies are about to reach the 40 yo mark. Awesome!

Best from Canary Islands.
