The Willem programmer is a device for programming electronic memory such as erasable-programmable read-only memory (EPROM), and electrically erasable programmable read-only memory (EEPROM) types. It comes as a bare PCB and this one is version PCB 5.0. It also has an accompanying software CD, compatible with Windows operating systems, and the manual and operating instructions are on the CD. It requires a parallel data cable to connect to a computer. An extension cable with a 25 pin male connector at one end and female at the other should work.

PCB 5.0

Vpp LED

The red LED marked Vpp is very useful in making sure that the programming voltage is correct, as many memory chips require different voltage levels.

DIP Switch Settings

These DIP Switch settings are also very easy to configure. After selecting the memory integrated circuit, the software displays a diagram of how these switches should be set. The settings are obviously different for different chips.

ZIF Socket

Voltage Regulator

Power Supply

Cost / eBay

When I bought this programmer on eBay, there were many sellers with a similar product, and some of them will sell just the programmer board without the cables whilst others will sell the cables as well.

Anti-static Storage Bag

The board usually arrives in an anti-static storage bag.
