I didn't have much time available this weekend, so decided to scratch an itch and write another game for the Apollo Guidance Computer, something I hadn't done for a couple of years. It is written in AGC Assembly assembled into a binary using yaYUL. Back in the 1960s would have taken months for skilled women to weave into core rope memory - now I can just press F8 and it assembles and runs inside an AGC emulator in less than a second.
The game is a version of the classic code-breaking game Bulls and Cows, with the premise being that in a parallel universe the Soviets have infiltrated the Apollo 18 mission and all communications between Houston and the AGC in the Command Module are blocked - unless the astronauts can solve the puzzle.
While the machine is blazingly fast for something so early in the history of computing, we are somewhat restricted in the types of games we can make as the display consists only of 21 seven-segment displays - six of which come in two-digit pairs and the other fifteen laid out in a 3x5 grid. I had already made versions of 2048 and Monster Maze for the system which are quite good fun and can also be played on my itch.io page.
It is possible to run AGC binaries in the browser thanks to the MoonJS port of the VirtualAGC emulator by Shahriar Iravanian.
