Hey lovely Mastodon folk. I've just released an HP-35, HP-45, HP-80 simulator called HP-1973 to celebrate the 50th anniversary of the HP-45 calculator. (Free) standalone versions for Mac and WIndows (no need for any Python installation or knowledge) & Python source for Linux. It's been a coding marathon, so it'd mean a lot to me if you could boost this post, so it gets in front of the right people. Download here: https://sarahkmarr.com/retrohp1973.html Enjoy. #retrocomputing#calculators#python#coding#rpn
@gsuberland Thank you. It went through a lot of iterations but the overall 'look' didn't change much. I wanted something that echoed the look of the originals, with a general 1973 aesthetic (although I slipped some later references into the themes).
@SarahKL Wow Sarah that looks incredible! I really need to improve my Transputer emulator’s debug display along these lines. You say it started as a few days then took over, dare I ask how many hours you put into it?
@M0CUV I lost track, but definitely 150+. Some of that was spent working through the logic diagrams in patents to get things just right, plus I was learning the details of Python/numpy/tkinter/nuitka... as I went.
@SarahKL Wow, looks amazing! I guess it simulates things at the ROM level and doesn’t reimplement things in a modern language. Does simulation at this level include the (not very accurate) timer function accessible on the HP-45 by holding down CHS-7-8 keys simultaneously?
@stuartmarks It absolutely simulates things at the ROM level: everything the calculator does is done using its ROM code, including any bugs in the original. And yes, the timer function's all there. It just uses '?' to generate the necessary keycode, rather than a combination of keys: then the ROM code does its thing.
@jaseg Thanks: I was going for retro-chic. (Also, I couldn't be bothered to teach myself a more modern windowing environment, for now. Shh: don't tell anyone.)
@elb Thanks so much for taking the time to let me know: it's been a solitary (if mostly enjoyable) task coding, so knowing that people are enjoying the result is fantastic.
@andyh2o@stooovie OK. I think it's fixed. Could you download and try? (If you're still getting a version with the json files visible, then you're downloading from a cache somewhere: should just be the app and a txt file.)
