Here is what I get confused about... Surely a laptop prototype based on such a tested and well-worn CPU with 48K of RAM would be cool, but shouldn't it sip power? Like shouldn't it last for like months on a charge? Or am I revealing my very meager and outdated understanding of engineering with only a bachelor in computer science from like 2004? | ||

It's gotta be integrated together (and possibly be at a smaller process size) before you get all the power savings. If you have a real 6502, it has no internal RAM or cache, and you need to send power back and forth to the RAM chips. (I presume it's SRAM, but it could also be PSRAM) If you ran a 6502 emulator on a cheap ARM SOC, it would be much lower power. | ||

There used to be small IBM PC compatible "palmtop" computers capable of running for many days on a pair of AA batteries. HP 200LX was pretty cool. I think it had 80C186 running at 10 MHz or thereabouts, with 1MB of RAM, monochrome graphic LCD and PCMCIA cards for storage. Norton Commander and Turbo C run on it without any problems. | ||

The display also takes power, quite a lot actually - 2-5W | ||
