Can anyone with Macintosh experience help me, please? 1) How do I check the amount of memory installed without ripping open the beast? 2) The machine was running some programs (Chess, for example) and suddenly refuses to do so, claiming, "xxx K needed to run this program. You have 512 K). Customer doesn't know how much was installed. Might this be a configuration problem, or has it lost contact with half its RAM? (and it hasn't even hit 40 years yet!) Thanks, manney(a)nwohio.com
