Re: Custom Firmware for the MZ-RH1 – Ready for Testing
#2I’m so glad Minidisc is having a resurgence. I don’t know if I’ll end up getting a MZ-RH1, but for the lucky folks who do, nice to see they’ll get some nice QoL upgrades!

#3Looking through the code is really interesting! I've always wondered how the code for these sorts of embedded devices worked (namely microwaves).

#4I have an MZ-RH10 lying around somewhere that would be neat to try working on.
Some folks have recently done screen replacements on those and that might be worth doing first.

#5always wanted one of these models then prices skyrocketed. now there’s not much of a point as the primary novel feature, uploading, was reverse engineered for all other NetMD models (ones that take standard batteries and have screens that don’t burn-in), just need a WebUSB browser and go here: https://web.minidisc.wiki/

I recently went down that rabbit hole, just look up how often embedded devices use fixed-point arithmetic to compensate for the lack of FPU units on the chips.

Asivery screen replacement is great. Need some soldering skills but it's wonderful.

#8I'm on the MD Discord and been following all of this, a bunch of us updated before the official launch and found a few bugs in the process, but the firmware itself is fabulous.

#9> discovered a boot ROM mode that can be enabled by bridging two GPIO lines on the mainboard (HSALF / TP8232 / R853 and WDT / SL901) to ground
How do you even find something like this?

There's still bargains to be found, I (honestly) picked up a mint RH1 from Ebay for £180 last year.
