      Great seller! A Man of his word. Bench Tested ULSI 80387sx 16-40 MHz Coprocessor and it runs very well at 33MHz. Condition was brand new as described and a great value. Seller shipped right away and was delivered ahead of estimated delivery date. I would not hesitate to buy from this seller again. Highly recommended AAA+++. Thank you for a smooth transaction.

      Excellent seller with quick shipping. Ran some benchmarks and this ULSI FPU seems to provide a roughly 10-20% boost over the Intel 387sx clock for clock (depending on the task and program). Neat little chip.
