ah, right, the Japanese MSX you mentioned was for a different person :)
Yeah, sounds like it was just the RTC batteries then. With a bit of luck they haven't done so much damage already that it can be replaced with a button cell (and probably one of those one way resistors so the machine won't try to charge the button cell). I'll check tomorrow when I'm at my laptop again if I can find a guide for you/Dozer.
Not sure if the #NMS8245 also offers the option, but the #NMS8250 also had a jumper in the form of a soldered rod that allows you to set it to 240V rather than 220V; that should help reduce some heat production with current level of mains power. I'll ask if that's also the case with this model.
@[email protected] while I have a strong nostalgic feeling for the #NMS8250 because it's what I grew up with, I do think the design of that 'pizzabox' is rather lackluster. It's not that different from the #Sanyo #MPC25 aka #Wavy25 it was based on though: https://www.msx.org/wiki/Sanyo_MPC-25
The earlier #NMS8235 and #NMS8245 looked much nicer imho. Though there's something to be said for having a separate keyboard you can easily replace and a main case you can shove underneath, or on its side next to, your monitor.
@clacke not that uncommon :)
The #Philips #NMS8255 for instance is an #MSX2 with not one, but two 3.5" DoubleDensity floppy drives. :)
One more than its brother, the #NMS8250 that I got (though one of mine was eventually modified to have a second drive installed too).
The earlier #VG8235 looked cooler, with its built-in, adjustable keyboard, but only had a single 3.5" *single-sided* disk drive. The #NMS8245 looked similar, had a 2DD drive, but a fixed keyboard
