A trip down memory lane
With how cheap and easy-to-integrate modern memory chips have become, it's easy to lose track of the fact that it wasn't too long ago that memory was the limiting factor in most computer designs. Before the advent of silicon memory, engineers had to make do with all sorts of weird and wonderful technologies just to provide a few precious bytes of memory. Things like intricate webs of wires spangled with ferrite cores, strange acoustic delay lines, and even magnetic bubbles were all tried at one time or another. They worked, at least well enough to get us to the Moon, but none would prove viable in the face of advancements in silicon memory.
That doesn't mean that retro memory technology doesn't have a place anymore. Some hobbyists, like Andy Geppert, are keeping the retro memory flame alive. His Core 64 project puts a core memory module in the palm of your hand, and even lets you "draw" directly to memory with a magnet. Andy learned a few tricks along the way to that accomplishment, and wants us all to appreciate the anachronistic charm of retro memory technologies. Stop by the Hack Chat to talk about your memories of memory, or to just learn what it used to take to store a little bit of data.
