Modern 64-bit Windows versions do not natively support the 32-bit parallel port drivers required by the Willem software. To make it work, you must follow these steps:
The red warning light on the Willem PCB50B blinked with the slow, rhythmic persistence of a dying heartbeat.
Elias rubbed his temples, the glow of the CRT monitor casting long shadows across his cluttered workbench. It was 2:00 AM. To his left sat a pile of vintage Commodore 64 cartridges, their shells cracked and labels peeling. To his right, the object of his frustration: the Willem PCB50B Universal Programmer.
It was a humble tool by modern standards—a parallel port relic from an era when computers had big beige boxes and pins you could actually see without a microscope. But for Elias, who ran a niche restoration shop for retro electronics, it was the only way to bring these old chips back to life.
He had rebuilt the power supply on the Willem unit. He had checked the voltage on the ZIF socket. He had even replaced the aging parallel cable. But when he tried to read the EPROM of a rare 1984 game titled Phantom Quest, the software threw a generic error: Device Not Detected.
"It’s not the hardware," Elias muttered to the silence of the room. "It’s the driver. It’s always the driver."
He turned back to his laptop, a rugged old ThinkPad running Windows XP, the last OS that truly loved legacy ports. He opened the browser, the dial-up connection screeching in the background, and began the hunt.
The Search for Version 0.98
The challenge with the Willem PCB50B wasn't the hardware; it was the fragmentation of its software. The internet was littered with versions—0.97a, 0.97g, 0.98d5. Forums from 2006 were filled with cryptic advice: "If you have the 'B' revision, you need the specific build for the timing crystal adjustment."
Elias navigated to a dusty corner of an electronics forum he hadn't visited in a decade. A sticky post, untouched for fifteen years, caught his eye: “Ultimate Willem Software Repository.”
He clicked the link. It redirected to a warning page. “This site is not secure.” He clicked past it, entering a digital graveyard of broken images and FTP links.
He needed the "Willem EPROM Programmer PCB50B Software Download 0.98d." This specific version supported the newer USB-to-Parallel adapters and, crucially, fixed the timing jitter that was likely causing his read errors.
He found the file buried in a .zip archive. The file date read: October 12, 2005.
"Let’s hope the old magic still works," he whispered.
The Installation
The download finished. Elias extracted the files. There was no fancy installer, just a standalone executable (willem.exe) and a handful of .dll files. This was software from a simpler time—drag, drop, run.
He double-clicked the icon. The familiar, utilitarian grey interface popped up. It looked like a cockpit from a Soviet spacecraft—rows of checkboxes for chip types (27C256, 28F series, SPI Flash) and drop-down menus for voltages. Note on Safety: Be very careful when downloading
He went into the Hardware Setup menu. This was the critical moment. The Willem PCB50B was notoriously finicky about the LPT (Parallel) port address.
He applied the settings.
The room was silent. He reached over to the Willem box and flipped the toggle switch to "ON." The green LED lit up. Then, he clicked the "Test Hardware" button in the software.
Click.
The software didn't freeze. It didn't crash. A small text box in the bottom left corner turned green.
Hardware Found.
The Read
Elias exhaled a breath he didn't know he was holding. He carefully placed the Phantom Quest EPROM into the ZIF socket, locking the lever down. He selected the device profile: 27C256 - 12V VPP.
"Okay," he said. "Let's see your secrets."
He clicked Read.
The progress bar stuttered, then began to fill. On the Willem unit, the red activity LED began to flicker rapidly—a frantic morse code of data transfer. The software was pulling the binary data from the silicon, byte by byte.
Reading address $0000... Reading address $1000...
It was slow. agonizingly slow. The parallel port shuddered under the weight of 32KB of data. But it was working. There were no errors. No "VPP Range Errors." No "Buffer Mismatch."
The Verification
Three minutes later, the bar hit 100%. The screen populated with hex codes.
00 EA EA EA 4C 00 10...
Elias stared at the hex editor window. It wasn't empty (00) or corrupted (FF). It was code. He scrolled down to the footer. There, in the hex, he could almost see the signature of the programmer who had written this thirty years ago.
He hit Verify.
Buffer matches device!
Elias leaned back in his chair, the springs creaking. He burned a new EPROM, swapped it into the cartridge shell, and walked over to the test bench. He slid the cartridge into the Commodore 64 and flipped the power switch.
The screen flickered, shifted to a light blue, and then, a pixelated ghost sprang onto the screen. The title screen for Phantom Quest appeared, accompanied by a scratchy, synthesized chiptune.

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

Additional Resources
The original software for the PCB50B is legacy Windows-based. You can find standard and updated versions through these sources: Official & Community Archives:
Minus Zero Degrees Archive hosts the v98D12 ISO image, which is the most compatible version for the PCB50B.
Shrubbery.net provides a repository of older versions, including 0.98D5 and 0.97ja, which may be needed if you set your board to PCB3B compatibility mode.
KEE Electronics often carries software versions compatible with PCB5.0 boards. Key Compatibility Fixes
Because the Willem software was designed for older versions of Windows (98/XP) and relies on direct parallel port (LPT) access, it often fails on Windows 7, 10, or 11 (64-bit). Use these fixes to get it running:
Port Drivers: On 64-bit systems, you must replace the default io.dll with a 64-bit compatible version, such as Inpout32.dll or TVicPort, to allow the software to communicate with the parallel port.
Administrative Rights: Always run the software as an Administrator and consider using Compatibility Mode (set to Windows XP Service Pack 3).
False Positives: Antivirus software like Kaspersky may flag old setup files (e.g., setup_98D11.exe) as Trojans. This is often a false positive caused by old executable compression techniques. Hardware Setup Tips
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.
Windows does not allow direct hardware access to the LPT port for security reasons. You need the giveio.sys driver.
