Step-By-Step Anachronometric Solutions for Your DM42/Free42/HP-42S Calculator

Warning: The Ansari Anachronometer program found herein is provided “as-is” and subject to change at any time. The author and publisher offer no warranty of of any kind with regard to this keystroke program, including, but not limited to, the implied warranties of fitness as a temporal stress calibration tool. Dig a Thousand Holes Publishing shall not be liable for errors, anomalies, or paradoxes that arise from the use of this program. Do not meddle in the causal streams of time without proper training.

Though the patents for the actual Ansari Anachronometer are still held by the historically litigious Browne Chronometric Engineer, Inc., we’ve managed to reverse engineer its functions in a—as far as we can discern—unique keystroke program for your HP-42S (or DM42 or Free42). This is not a true emulation of the anachronometer, but rather a simplified simulation, based on observed behavior and the few materials from Browne Chronometric that have been made public.

The Calculator’s Game Design

This blog has seen more traffic in the past 48 hours than all of 2017, and it’s because of a little post about my other hobby, RPN calculators. When I made that post last week, I didn’t even have my DM42 yet. It was ordered it, but still in transit. Now that I’ve had a few days to play with it, and now that I see I have an interested audience, I thought I might say a bit more about it and why I find it so captivating.

But before I do, a brief introduction for all my new readers. Hello there, I am Epidiah Ravachol, author, tabletop roleplaying game designer, and calculator enthusiast. I have written and designed quite a few games over the years. Many of these can be found at the Dig a Thousand Holes Publishing store where until the end of February you can get them for 25% off using the coupon code DM42. You can also get back issues of my sword & sorcery magazine Worlds Without Master—packed with comics, games and weird tales about forbidden sorceries and high adventure. One game you won’t find there (because I published it through another company) is perhaps my most well-known: Dread, the horror game that uses Jenga instead of dice. Finally, I talk about these games, other favorites of mine, game design in general, and my love of calculators and math all over the Internet—on Mastodon, on Twitter, on Google+, on Instagram. I also co-host a podcast about The Rockford Files, for those of you who also happen to love 70s detective shows starring James Garner (which should be just about all of you).

And if you really want to stay up-to-date on my bullshit, sign up for my monthly newsletter!

Right, now on to the gorgeous DM42!

The Game Designer’s Calculator

If you’ve been following me on the social medias this week, you may have noticed a wee bit of excitement about a new calculator. It all starts with this tweet from Saturday:

Four short days later, it was justified and this wondrous calculator was ordered.

To celebrate, I’ve extended the sale through the end of February. So until then, you can still get 25% off of everything at the Dig 1,000 Holes PayHip store with the coupon code DM42.

While I wait for this beauty to arrive, allow me to tell you why I’m so excited about it and perhaps why you should be excited, too.
