| all absolutely excellent specimens. Not a single complaint.
| They are easily user serviceable, they have a very high build
| quality and feel like they will last decades (matching
| modelfkeyboards dot com build quality). The DM42 has a user-
| enabled N-stack so you can input algebraic expressions of any
| arbitrary length. The DM15L is an advanced calculator you (or
| at least I) can grok completely end-to-end, and packs it all
| into a compact form; I actually prefer to grab the DM15L before
| the DM42. The DM41X is also an excellent specimen. It includes
| the ability to {,un}load module files which are dumps of the
| old HP-41CX module cartridges. I love every single one of them,
| and cannot shill (for free) SwissMicros enough. You've beheld
| Swiss watches, now behold a Swiss calculator!

|
| And then of course there are many HP calculator emulators and
| others for android

| rendering for the entire screen during action.
