is a newer iteration, it still relies on software that expects direct access to a parallel port.
Standard Version: The most commonly recommended software for PCB5.0 and PCB50B boards is Version 0.98D6 or 0.98D12.
Older Boards: If your board is set to PCB3B mode via jumpers, you may need an older version such as 0.97ja.

is not a "plug-and-play" USB device. This is the most common point of confusion for new users:
Parallel Port (LPT): The USB port on the board is only for power. Data must be sent through a 25-pin parallel cable.
Operating System: The software was originally built for Windows 98 and XP.
Modern PCs: Running the software on Windows 7, 8, or 10 (especially 64-bit) often requires a custom io.dll fix to allow the software to talk to the parallel port. Setup Checklist

The Willem PCB50B is a versatile EPROM/Flash programmer that typically requires legacy software for operation. Because the hardware relies on the parallel (LPT) port, modern operating systems like Windows 7, 10, or 11 require specific drivers and patches to function correctly. Software Download & Files
The most compatible software version for the PCB50B is generally v0.98D12 or its derivatives.
Main Software Package: You can find repository versions such as EPROM50 via setup_PCB50_98D12C3 on GitHub. This repository also includes necessary installation steps for modern systems.
Legacy Mirrors: Sites like minuszerodegrees.net host ISO images of the original software CDs.
Note: Antivirus software (like Kaspersky) may flag these old executables as "False Positives" due to how they access hardware or use compression. Installation Requirements
To get the programmer working on newer systems (especially 64-bit), you must follow these steps:
Driver Support: Install TVicPort (specifically version 4.1) to allow the software to communicate with the parallel port on Windows NT/XP/7/10.
64-Bit Patch: For Windows 7 or 10 (64-bit), you often need to replace the standard io.dll with a patched version (like the one by Downtown Doug Brown) and include inpout32.dll in the installation directory.
BIOS Settings: Ensure your PC's parallel port is set to EPP or Normal mode in the BIOS. Key Features of PCB50B Cause: The 16-bit installer in old versions
Faster Programming: Claims to be 20%-50% faster than older Willem versions.
Chip Support: Supports SPI FLASH (3.6V), EPROM, EEPROM, MCS-51, and PIC microcontrollers.
Dual Power: Can be powered via USB (for reading) or an AC/DC adapter (required for writing/programming at higher voltages like 12.5V or 21V). Typical Setup Steps
Connect the 25-pin parallel cable to your PC and the programmer. Connect an AC adapter if you plan to burn/write to a chip. Open the software and select the device type.
Configure the DIP switches on the board as shown in the software's graphical interface.

Based on the keywords "Willem Pcb50b," you are looking for the control software for the popular Willem Universal EPROM programmer (specifically the PCB 5.0B hardware revision).
Because these devices are generic "clones" produced by various manufacturers in China, official support websites are often non-existent or difficult to navigate. However, the software is widely available in the hobbyist community.
Here is how to download and set up the software:
Error 4: Software crashes on Windows 10/11
- Cause: The 16-bit installer in old versions.
- Fix: Use v0.98d or newer. Alternatively, run Windows XP in VirtualBox and pass the LPT port through to the VM.
1. Overview
The Willem PCB50B is an older, low-cost universal EPROM/EEPROM programmer, commonly used for flashing BIOS chips, memory ICs (27 series, 28 series, 29 series, etc.), and microcontrollers. It connects via a parallel (LPT) port or USB (depending on the version).
The software is not available from a single official modern source – the original manufacturer no longer supports it.
Recommended Software Version
For the PCB50B board, the most stable and widely compatible software version is Willem EPROM Programmer Software v0.97 or v0.98 (sometimes labeled as Willem 0.97 or Willem 0.98).
- Do not use version 1.0 or higher: These later versions were designed for entirely different USB hardware (PIC-based programmers) and will not work with the parallel port-based PCB50B.
Official (Legacy) Willem PCB50B Software Download Sources
Since no official site exists anymore, the safest places are archival projects and open-source hardware communities.
2. Willem-LPT for Raspberry Pi
- Works with: Classic parallel-only PCB50B.
- How: Connects to the Pi's GPIO pins, emulating the LPT protocol.
- Result: Modern web-based UI for programming. No more driver hell.
Is the Willem PCB50B Still Worth Using in 2025?
The short answer: Yes, but only for legacy projects.
- Pros: Extremely cheap (often $10-20 on eBay), supports rare 21V EPROMs that USB programmers cannot handle, and has a passionate open-source community.
- Cons: Parallel port dependency, slow programming speeds, no USB 3.0 support, and requires vintage PC knowledge.
If you are repairing a 1980s arcade board, an Amiga, or a retro PC BIOS chip, the PCB50B is irreplaceable. For modern SPI flash or high-density NAND, buy a TL866II or Xgecu T48.
