Well, then you have to count the LGP-30 as computer with core memory, too,
because the interface to the (apparently extremly rare) magnetic tape
drives (yes, there were tape drives for the LGP-30!) contained core memory
as buffer. The drive would buffer the block in core so that the LGP-30
could read it with its own speed (and vice versa).
