![1999 vs 2009 [4032x3024 - 2MB]](https://pic8.co/sh/w8aboz.jpg){kind=link}
It's SATA vs IDE, so I imagine SATA is more optimized and that's why it's smaller? Lol
Just 10 years difference. I have a 1993 IDE drive around here somewhere, the circuit board on that looks like an electronics store vomited on it.
Sounds familiar. I have a huge circuit board that bends under its own weight and takes the entire lower space inside the case, apparently it was some weird Audio I/O thing or something: https://pic8.co/sh/P3y7pY.jpg Never used it, so I still don't know what it's really for.
Interesting, looks to have multiple crystals up front with a bunch of transformers to match impedances? Some sort of audio synthesis board?
Any names or model numbers on it?
I have a Quantum drive from 1988 or so (SCSI) and it still spins up and works. Look at those beefy motor/voice coil drivers with heat sinks. The three are probably the 3-phases of the spindle motor. The big one with 15 pins looks like the usual audio amplifier ICs, so I'd guess it's for the voice coil.
That's a wonderful looking board. It always amazes me how we've managed to compress that down to an ASIC that's a controller, some RAM, and a glue chip.
