My Quadra 700 is running off of a ZuluSCSI 1.1 and that works great but I definitely miss the noises from a physical hard drive. Specifically, I miss the crazy noises from the Miniscribe 8425S 20MB hard disk I had in my Macintosh SE back in the day.
I first thought of developing an extension which reproduces the sound but that would only kick in after the Mac boots. I decided to try something else first.
I was able to get my hands on a working Miniscribe hard disk and used a Tascam DR-40 to record the noises. I then cut it up into shorter samples and copied them into an Adafruit Audio FX Mini Sound Board. It can take 10 samples and play them back randomly using a pin as a trigger. The idea was to tie this pin to the LED activity light from the ZuluSCSI as a trigger.
I recorded a video of the first test below. The speaker I got (an Adafruit 3885 Stemma Speaker) is kinda weak and I'll have to find another option. Very much a hack but thought I'd give it a try.
