- No external power brick, like we had with the PicoPSU.
- Stock Atari appearance from the outside
- external switch to toggle between 030 and 060 modes, does not need to be integrated into the power switch itself.
- Room to connect storage module to Falcon's IDE header.
- Falcon's reset switch should still work (ideally in both 030 and 060 modes).
- Falcon's green power light operates as normal.
- The fan on the heatsink for the 060 chip should ideally only spin if Falcon is booted in 060 mode. This fan is just un-necessary noise when Falcon is booted in 030 mode. Not sure if you can control this via a PSU?
- Crucially the PSU must not explode when user switches it on, wiping out ££££ worth of sacred retro electronics
My only other thought would be to have some kind of visual indicator as to which mode (030/060) is currently in use. Possibly change the colour of the power light, or perhaps users could just manually check the position of the 030/060 toggle switch on the back.
One or two of the above requirements are 'nice to haves' rather than essential... but worth mentioning.
Good progress so far Exxos. I'm more than happy to user test one of your prototypes
keep up the fab work
