Here's a short summary of the Hacker News thread:
A Hacker News post highlights nicole.express's detailed write-up on the arcade game Kiki Kaikai and its hardware. The discussion focuses on specific RAM chips used in the game. One commenter points out that while the author speculates about the "70" stamped on some chips indicating faster speeds, the MCM2016HN45 chips, with a 45ns rating, are actually the fastest RAM on the board. The overall sentiment is positive, with another user immediately recognizing the author's work due to its quality. DocTomoe admires the craftsmanship and attention to detail that went into the hardware design, contrasting it with modern software development.
Overlooking a small detail there: the fastest RAM on that board would be the 2 chips marked MCM2016HN45 (the -45 means 45ns for that part, which is pretty fast for a RAM chip made in 1986).
Anyway, very nice & detailed writeup!
