Finally located 5 pieces of 20MHz oscillator in SOJ package for reasonable price. Ebay search didn't include this seller, it was in the links bar below the another through seller's main store links while looking at their 20MHz oscillator which costs 3.5 times as much.
For the experiment with slowing 386 or 486 down to 10MHz.
