Let&#x27;s see:<p>2 HP-41&#x27;s
1 HP-41C
1 HP-41CX
1 HP-48gx
1 HP-49g
1 HP-16C
1 HP-32S
1 HP-48S
1 HP-35S
1 HP-200LX
1 HP-Prime<p>All in perfect condition, manuals, original boxes, accessories.<p>Yeah, I&#x27;ve been into the RPN thing for quite some time.<p>Favorite?<p>The 35S sits by the CNC machining center inside a zip-loc bag to keep oil and metal shavings off of it.<p>Desk-side is mostly the 41CX.<p>One of the things nobody has mentioned yet is how much better the 41&#x27;s LCD display is when compared to ALL other HP calculators, excluding Prime.  I tend to do a lot of coding and CAD work under subdued lighting.  The 41&#x27;s display is very easy to see just with the monitor&#x27;s illumination.  The other&#x27;s suffer from low contrast LCD&#x27;s that are hard to see outside bright office environments.  Prime is self lit so that&#x27;s not a problem.<p>I had a couple of others but gave them away.  One was an HP-50g and the other was a folding model, just can&#x27;t remember the model number.  Yeah, HP has made some, well, less than great calculators.
