The EP701 is no longer available. It was designed to program the MC68701/U4 single-chip microcomputers. The article describing this design appeared in the May 1990 edition of Modern Electronics. Lucid Technologies sold the last EP701 in July of 2003.
A 68701 programming module is now available for the LP120.
If you don't want to purchase your own programmer, Lucid can provide programming services. Lucid can program your 68701 parts, or read the code out of old parts. See the Lucid Technologies Device Reading and Programming Services page for prices of these services.
