On 27—28 April 2013, the Atari Calculator was displayed at the 14th Vintage Computer Festival Europe (VCFe) in Munich, and Vortrag Wassenberg made its presentation. Slides from this presentation were published online.[36]

On 22 November 2013, Peter Dell[37] released a ROM cartridge version of the modified original Atari Calculator with adding startup screen, as a personal gift sent to Carol Shaw:[38]

{{Blockquote|text=My cartridge was created as a personal gift for Carol. It is explicitly based on the released disk version and includes a complete DOS, so [it] can be used reasonably even you do not have a disk drive (which was the case for her).|author=Peter Dell|title=Calculator|source=https://forums.atariage.com/topic/351420-calculator/?do=findComment&comment=5257217}}

In 2013, Norbert Kehrer ported the original Atari Calculator to Commodore 64.[39][40][41]

On 5 November 2014, the Atari Calculator was highlighted on the 'Inverse ATASCII Podcast'. The podcast site also published the source of the example program for the Atari Calculator, newly created cheat sheet, screenshots of software screen in various modes and an excerpt from the original user manual showing a mistake on instruction illustration.[42][43][44]
