If you type:
OUT (255),4
And the machine does NOT crash, it has 64kb. If it did crash, it has more. Try:
OUT (255),8
If that didn't crash the machine, it has 128kb.
Another possibility is that the machine doesn't have mappers, in which case it
has 64kb ram. Try:
OUT (255),1
If that didn't crash it, it has 64kb unmapped RAM.
