A healthy selection of HP calculators

Post by badacktor »

this is by no means comprehensive, rather it was just some of my favorites. and since I set up a good workflow for resizing images, tweaking brightness and contrast, and dropping into 1-bit floyd-steinberg dithering, I figured I'd just bang out a whole mess of 'em. I was extremely tempted to label the "three quarter" / "isometric" whatever ones 15C_DUTCH_ANGLE.bmp but I resisted.

and to make it easier, here's just a big dump of all 50 bitmaps I've got on my DM41X right now, including one of the preloaded images, screen shots of Windows 3.11 and Macintosh System 1 running their calculator apps, some slides from an old HP presentation, the pillars of creation from the eagle nebula, even a screenshot of the Information Superhighway from Space Quest 6. (an adventure game series I adored as a baby) Let me know if you end up using any, maybe even drop a photo of your calculator's extremely cool new custom off image screen!

this might be a good place to suggest a small li'l image viewer for screenshots and OFFIMG files on the calculator itself. use the up and down arrows to scroll through images, etc. unless there already is one and I'm a dingus that missed that line in the manual!

There isn't the space for that. The DM42's ROM is getting pretty full now and we wouldn't want to include unnecessary stuff to the detriment of actual functional stuff.

If you only want one OFFIMG then make sure its .bmp file is the only one in the OFFIMG directory. If multiple files are in there, then the DM42/DM41X cycles through them each time it is powered down.
There are only 10 kinds of people in the world: those who understand binary and those who do not.

At the bottom line it's a calculator, not a picture book.
WP43 SN00000, 34S, and 31S for obvious reasons; HP-35, 45, ..., 35S, 15CE, DM16L S/N# 00093, DM42β SN:00041
