Who wants a new printing HP-42s?

More thoughts on this:

I think the proper description for what I have in mind is a "desktop dock" for the DM42P.

Here's a video of an extremely crude mockup I made last night (out of paper!):

The dock would:

1 - Angle the calculator toward the user, more suitable for desktop (vs. handheld) use.

2 - Have a printer

3 - Have a backlit color TFT LCD display duplicating what's on the calculator's LCD, but angled at 30 to 45 degrees toward the user for desktop use. (See how the HP-97 display is angled for comparison.)

4 - Maybe, have batteries so the whole docked device can be portable (I really don't need this but other people might want it).

To make this work, the top of the calculator needs to have connectors that fit the dock, including:

A - DC power input (probably USB)

B - IR (or wired) printer output

C - Display data output (to drive the angled display)

Item C seems the most challenging (I suspect that isn't available now).
