The short answer: Yes, but only for legacy projects.
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.
The Willem PCB50B is a versatile EPROM and microcontroller programmer known for its cost-effective "open" hardware design. Managing the software and configuration is essential for successful chip flashing, as the device relies on specific software versions to match its hardware settings. Core Software Versions
The PCB50B board typically supports two main branches of software, selectable via onboard jumpers:
Version 0.98D12 (or 0.98xx): This is the modern standard for PCB50B boards. It supports SPI Flash chips found in newer motherboards and DVD burners and is roughly twice as fast as older versions due to improved programming algorithms.
Version 0.97ja (or 0.97xx): Used primarily for legacy operations or if the board jumpers are set to the older PCB3B compatibility mode. Key Features & Compatibility Standard PCB3B Willem Programmer User Guide - MCUmall
I’m unable to provide a direct download link or a full software report for “Willem PCB50B” because it refers to a specific piece of legacy hardware (a universal EPROM programmer) and its associated software. However, I can give you a detailed informational report to help you locate the correct software safely.
To summarize, do not risk downloading from random banner-riddled websites. Instead, use these safe, verified sources:
After downloading, remember the golden rules: run the InpOut32 installer as Administrator, set your BIOS LPT mode to ECP, and always use an external 12V power supply. With the correct software and setup, your Willem PCB50B will continue to serve you for years to come.

Disclaimer: The Willem PCB50B is legacy hardware. No official support exists. Always scan downloaded files with Windows Defender or Malwarebytes. The author is not responsible for hardware damage due to incorrect voltage jumper settings.
The Willem PCB50B software is primarily distributed as version 0.98D12, which remains the standard for this legacy hardware. This version is essential for users of the PCB50 series because it introduces stable support for 3.3V–3.6V SPI Flash devices and includes improved algorithms for SST 25 series chips. Essential Software Downloads
Because the original developers no longer maintain a central repository, the software is available through several reputable community and legacy sources:
Version 0.98D12 (Standard): This is the most widely used version for PCB50B, supporting modern SPI Flash chips found on newer motherboards and hard drives.
Version 0.97ja (Legacy): Often recommended for older chips or as a base installation before applying patches for modern operating systems. Drivers and Patches:
TVicPort: Required for the software to access the parallel port on Windows NT/2000/XP and later.
Remapped IO.DLL: A critical patch for 64-bit Windows users (7, 10, and 11) to allow the software to communicate with non-standard parallel port addresses. Installation Guide for Modern Systems (Windows 10/11)
Installing the Willem software on modern 64-bit systems requires manual configuration of the parallel port communication:
