Well, let me see. The machine is not too useful because of dead battery, but I don't believe RAM would be a problem. It has 512MB or more, IIRC. Missing PAE is, and missing instructions are. And horrible keyboard and bad driver support from Linux. And... Ouch and fact that I use its power supply to power something else. It looks similar to this: https://hexus.net/tech/news/laptop/13994-kohjinsha-launches-impressive-subnotebook-twist/ (but has no touchscreen). Bios is "built 03/02/2007". CPU is "AuthenticAMD" family 5 model 10, "Geode(TM) Integrated Processor by AMD PCS". 500 MHz, flags "fpu de pse tsc msr cx8 sep pge cmov clflush mmx mmxext 3dnowext 3dnow". 512MB RAM. This is not a suitable compile server, but still could work as a subnotebook given right software...
