I can't speak to the purchase price of core memory. But I believe most
S/360 and S/370 mainframes were leased in those days. I have a vague
recollection (circa 1969) of core memory leasing for $7,500/month for 256KB.
Someone who remembers what the lease:purchase ratio was will have to do the
conversion.
