got a VERY big PlayStation 1 in the mail today, the original board for the first versions of Beatmania IIDX!

it plays videos by controlling a full-ass external Hi-Fi DVD player over a proprietary serial link, muxes that output back into the video signal, loads the game through a SCSI CD drive and gets its sounds from an IDE hard drive... somehow it all still seems to work after almost 25 years!

DDR-IIDX cabinet link imminent 👀
The full setup: the three-board Twinkle system at the bottom, hooked up to a DVD player sitting on top of it, and an amplifier on top of *that*. It boots!
Insides of the Twinkle: three boards, the top one containing the PS1 chips and the I/O boards, the middle one taking care of the video and muxing the DVD signal back into the output, and the bottom one doing all the audio, loading the files from a HDD by itself using a separate MC68k CPU

@Shiz Those old electronics are amazing for what they accomplished, nothing was impossible in the 70s and 80s

Wow... all of that was inside the cabinet? That's crazy...
