Probably the slalom ski game I vaguely remember playing on a HP85A my dad brought home from work some weekend. Can't find a video of it unfortunately. I remember the flags drawn on the screen, and using keys to control a dotted line going from the top of the screen down.
I'm pretty sure I remember that one! I think I played it on a different platform though. What is a HP85A? If I google it I get toner cartridges as results.
Correct name seems to be HP-85A, with a dash.
https://en.wikipedia.org/wiki/HP_series_80http://www.oldcomputers.net/hp85.html"16 KB dynamic RAM, a 5-inch CRT screen (16 lines of 32 characters, or 256×192 pixels), a tape drive for DC-100 cartridges (210 kB capacity, 650 B/s transfer), and a thermal printer. Both the screen and printer display graphics in addition to text, and the printer can copy anything shown on the screen". 0.625 MHz CPU.
Wikipedia links to a Windows emulator for the 80-series:
http://www.kaser.com/hp85.htmlFound a video of someone showing off the HP-85A at
https://youtube.com/watch?v=ov3Z02tE5EE and around 0:29 there is a file-listing visible on the screen that has a file called SKI! That must be it. Now I just have to figure out how to load it in the emulator, assuming it is included in one of the three game ROMs I found for it.
UPDATE: Yes! SKI is in the included Standard ROM, not one of the game ROMs. It runs, but much too fast even when setting the emulator to "natural speed". Game over in approximately one frame. But it was fun just to see it run anyway.
