GROUP RECONSIDERS COMPUTER MEMORIES <CMIN> BID A shareholder group led by Far Hills, N.J., investor Natalie Koether said it is reconsidering its plan to seek control of Computer Memories Inc and now plans to sell its entire stake in the company. In a filing with the Securities and Exchange Commission, the group, which includes Sun Equities Corp, said it sold a net 365,375 Computer Memories common shares between March 5 and 17 at prices ranging from 3-3/4 to four dlrs a share, lowering its stake to 687,000 shares, or 6.2 pct of the total outstanding. The group said it reconsidered its takeover plans after the company announced it agreed to a stock swap. On March 12, the Chatsworth, Calif., computer disk drive concern said it agreed in a letter of intent to exchange 80 pct of its stock, all of which would be newly issued, for the assets of privately held Hemdale Film Corp, with Hemdale as the surviving entity. "In light of these disclosures, Sun found it necessary to re-evaluate the feasibility of seeking control of the company and has sold a portion of its shares and currently intends to sell the balance thereof from time to time," the group said. The group, which disclosed plans on Dec 29 to seek control of the company, reserved the right to change its mind again.
