I'm familiar with the Data I/O System 19 and 29B programmers, and their differences. 1. Can someone tell me where the 29A and 100A programmers fit into this family, and how they differ from the 19 and 29B? 2. I'm trying to use a UniPak on a System 19. How do I enter the manufacturer and device codes? The Unipak manual says to see the system manual, and the system manual says to see the Pak manual!
