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).
