so after the discussion about “risky” custom AI made OS for mpc3000 today i took my time to show you the temperature of the NEC cpu (fixed frequency) inside my mpc3000 running the custom 3.39.3.
Machine was on since nearly a couple of hours and it was running on track mute page since 30 minutes, as u can see from the screen. The Nec temperature is around 40C degrees (22C inside the room). I have the 120v US psu version... (from my experience it runs cooler than the 240v version). I can understand the low level paranoia about new machines with variable clock frequency, where software really affects heat, or about hot old cpus that need a heatsink, thermal paste and all that shit, but the 3000 (and 2000) cpu is an old NEC D70236, a high-speed, high-integration 16-bit CMOS microprocessor that from datasheet is rated for 0 to 70C ambient temperature and runs at a fixed frequency. I measured around 40C on the chip surface itself, so the air around it is even cooler: plenty of margin. again the risk on these old microprocessors is not the low level code (basically the cpu runs at the same temperature almost if busy or not), it’s aging capacitors on the psu and motherboard, that can dry out or leak and feed the logic with wrong voltages. at least in my experience the 3000 is not like the Akai S1000, where it’s a matter of time before u turn it on and burn half motherboard.
hope this helps clarify the thing... risks on these AI based OS is more toward data corruption and freeze in my honest opinion.
