The software is useless without proper chip settings. Here is a quick reference for common chips on the Willem PCB50B:
| Chip Type | Example | Software Selection | Jumper Settings (PCB50B) | | :--- | :--- | :--- | :--- | | 27 Series EPROM | M27C256B | 27C256 | J1=Closed, J2=Open, Vcc=6.5V (verify) | | 28 Series EEPROM | AT28C256 | 28C256 | J1=Open, J2=Closed, Vcc=5V | | 29 Series Flash | SST29EE020 | 29EE020 | J1=Open, J2=Closed, Vpp=5V | | AT89 Series MCU | AT89C51 | 89C51 | Use external 12V adapter. J3=12V |
Always double-check: Overvoltage (e.g., applying 12V to a 5V-only chip) will destroy both the chip and the PCB50B.
The Willem PCB50B remains an invaluable tool, but its software ecosystem is a digital archaeological site. By using the safe download sources and installation methods outlined above—prioritizing GitHub, The Retro Web, and the Internet Archive—you can avoid malware and focus on what matters: reading that vintage BIOS, dumping a rare arcade ROM, or bringing a 1980s computer back to life.
Final Checklist:
Do you have a unique chip that isn't listed? Consider using the "Custom Chip" feature in v0.98d—but that is a topic for our next deep-dive guide.

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. Willem Pcb50b Software Download
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:

Additional Resources
Willem PCB5.0B (often referred to as the PCB50) is a versatile, low-cost EPROM programmer widely used for BIOS flashing, automotive tuning, and vintage computer repair. Because it is an open-hardware design, the software is primarily maintained through community archives rather than a single corporate website. Software Download & Compatibility The primary software for this hardware is typically version
. You can find reliable downloads through these community-trusted sources: Sivava.com
: One of the original distributors of Willem-style programmers. They host the standard "Willem Eprom Software" packages. The software is useless without proper chip settings
: Another common source for the PCB50B specific driver and software sets. GitHub Repositories
: Search for "Willem Programmer" on GitHub to find community-updated versions that may include better chip definition files ( Crucial Technical Requirements
Before downloading, ensure your setup meets these hardware constraints: Parallel Port (LPT) : The PCB50B communicates via a DB25 parallel port . Most modern USB-to-Parallel adapters will
work because they do not support the direct bit-banging required by the software. Operating System : The software was designed for Windows 98/XP. To run it on Windows 7, 10, or 11 (64-bit) , you must: Install the DLPortIO driver Run the application in XP Compatibility Mode Driver Signature Enforcement in Windows settings to allow the LPT driver to load. Quick Setup Steps Connect Power
: Use a USB cable or a 12V DC adapter (check your board's jumper settings for power source selection). Set Jumpers
: Reference the "On-Screen Jumper Guide" within the software. Every chip type requires a specific physical jumper configuration on the board. Test Hardware : Open the software and go to Help > Test H/W to ensure the PC sees the programmer through the LPT port. Do you need help finding the specific jumper settings
for a particular chip, or are you having trouble getting the to respond?
If the standard software fails, consider these alternatives:
What to avoid: Any site with "soft32.com," "driveridentifier.com," or pop-ups telling you to update your Flash player.
Since no official site exists anymore, the safest places are archival projects and open-source hardware communities. The Willem PCB50B remains an invaluable tool, but
Navigate to SourceForge and download the OpenWillem_0.98.4_Win64.zip file. Extract it to C:\Willem.
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).
