I was musing today about the old recirculating stores (mercury delay
line, magnetostrictive, acoustic, etc.) used for memory on old iron.
Suppose one wanted simulate one in modern components. How would you
do it, if you had, say, a million bits to store?
Would you use a 1x1Mb DRAM and a counter to cycle through the
addresses? Or an 8x128Kb SRAM with an external 8 bit shift register?
Any other thoughts? Access has to be read and write and make the
bitrate about 10MHz.
Cheers,
