This is very important when you want to smoothly and reliably burn those old CMOS and even older NMOS EPROM chips. Optional higher Vcc voltages (5.6v and 6.2v) will be available when an external AC power supply is used. Quality components are used, for example, the high current tolerant coil is used to boost the robustness of the circuitry. High precision digital switching ICs are used to control the Vpp circuit ( vs cheap regular transistor controlled, used in other manufacturers products), thus dramatically improves the burning accuracy and reliability by multitudes. The PCB layout is fully optimized and the digital circuitry is separated from the power supply circuit, thus reducing interference. A FREE PLCC32toDIP32 adapter will be included for your convenience if you happen to have PLCC32 package chips to program.
This board has many enhanced features, such as built-in dedicated SPI BIOS ZIF socket and DIP FWH / LPC socket, thus NO NEED to pay extra to purchase these optional adapters. Introducing our newest Universal Willem EPROM programmer PCB version PCB6.0E LPT version.
