It’s challenging to keep the memory modules running. They consist of a woven mat of core memory with fine wires running through the cores to read and write the data bit that was stored in each core. It’s difficult to repair the core memory because everything is so small: Each thing that looks like it might be a core is actually four cores on edge. Each core has five wires going through it and they’re all suspended by the mat of wires that go through the cores. It's funny to see "everything is so small" -- these are giant compared to lithographically formed semiconductor memory. But it's not exactly wrong either. The parts are small enough to challenge the human sensorium and motor control, yet still large enough to tempt interaction using your own eyes and fingers.
