Help identifying unlabeled modules

Postby ScottJ » Sat Feb 20, 2021 2:13 am

I could use some help identifying some modules that came in a 41CX I just bought. There are three of them. They were apparently cleaned of all external labels by a well-meaning restorer.

One is clearly a dual X-Memory module - when it’s installed, my CAT 4 jumps from 124 to 600 registers. Love it.

The other two return stuff I have never seen in CAT 2.
First module:
DST 12V4}5
DST 12 1V
DST 12+2V
DST 12-2V

Second module:
DIST 12 V3
DIST 12 -1
DIST 12 +2
DIST 12 -2

Any ideas? Any help appreciated.

Hmmm... They don't show up in the HP-41 module database at https://calc.fjk.ch/db/hp41mod.php. They're probably custom, maybe a one-off?

I have a double extended-memory module too. It sure is nice to have that.

Thanks, Garth. That list was one I checked when trying to ID these. It’s too bad there's no easy way to see the program names and function names the module adds. Those would be a bigger clue. But hey, having a rare, unique module is pretty cool!
