The EP705N is no longer available. It was designed to program the MC68705P3/P5/R3/R5/U3/U5 single-chip microcontrollers. The article describing this design appeared in the January 1994 edition of Electronics Now. Lucid Technologies sold the last EP705N in July of 1998.
A 68705 programming module is now available for the LP120. This programming module also allows the LP120 to READ a programmed 68705P chip, something no other programmer can do.
If you don't want to purchase your own programmer, Lucid can provide programming services. Lucid can program your 68705 parts, or read the code out of old parts. See the Lucid Technologies Device Reading and Programming Services page for prices of these services.
