The T48 universal programmer (also known as TL866-3G) has become a go-to tool for electronics enthusiasts, repair technicians, and retro-computing fans. Its wide chip support, reasonable price, and compact size make it a practical choice for reading, writing, and verifying EEPROMs, EPROMs, Flash memory, microcontrollers, and more.
But owning a T48 is just half the equation — to make the most of it, you need the right software. The T48 is only as good as the interface that drives it. In this article, we’ll explore the recommended software for the T48, from the official XGPro suite to open-source alternatives like Minipro, as well as cross-platform solutions, installation tips, and troubleshooting.
By the end, you’ll know exactly what to install, how to use it, and which software fits your workflow — whether you’re on Windows, macOS, or Linux.
1. Meet the T48 Programmer
Before diving into software, let’s quickly set the stage.
The T48 is the successor to earlier TL866 models (like the TL866A and TL866II Plus). It supports over 35,700 devices at the time of writing, including:
Parallel and serial EEPROMs
NOR Flash chips
EPROMs (with UV erasure capability)
Microcontrollers from brands like PIC, Atmel, ST, Winbond, etc.
GALs and PALs
It offers programming voltages up to 25 V, making it capable of handling older devices that newer low-voltage-only programmers cannot. The hardware communicates over USB and relies entirely on software to perform chip identification, reading, writing, and verification.
2. The Official Software: XGPro
When you buy a T48, the manufacturer expects you to use XGPro (also referred to as the XGecu software). This is the official application from the makers of the T48.
2.1 Why XGPro is Recommended
Complete Chip Support The T48 supports tens of thousands of devices, and XGPro’s database includes all of them. If the chip is listed in the official “T48 Supported Device List” (a downloadable TXT file on XGecu’s site), you can program it.
Native Compatibility XGPro is designed specifically for the T48 hardware. No extra configuration or drivers are needed beyond the included installer.
Frequent Updates The developer regularly updates the device list and fixes bugs. Using the latest XGPro ensures maximum compatibility.
Full Feature Access Supports advanced options like:
Blank check
Bit-wise verification
Fuse/lock bit configuration for MCUs
Batch programming
Multi-Language Interface
Available in English, Chinese, German, Italian, Spanish, and more.
2.2 Installing XGPro
On Windows:
Download Go to the official XGecu website (or authorized resellers like eater.net or xgecu.myshopify.com). Download the latest XGPro package for the T48.
Install Run the installer. Follow on-screen instructions to install drivers and the main application.
Connect the T48 Plug the T48 into your PC via USB. The software should detect it automatically.
First Launch The program opens with a chip selection window. You can test it in demo mode even without a chip inserted.
2.3 Using XGPro
The workflow is simple:
Select Your Chip Click “Select IC” and search for your device by part number.
Insert the Chip Place it in the ZIF socket, matching the orientation diagram.
Choose Operation Read, Write, Erase, Verify, or Blank Check.
Run and Monitor Progress bars and status messages keep you informed.
2.4 Pros and Cons of XGPro
Pros
Complete chip support
Easy to use
Regular updates
Built-in chip database
Cons
Windows-only — macOS and Linux users need workarounds (Wine or virtual machines)
Official download site can be a bit clunky to navigate
3. The Open-Source Alternative: Minipro

While XGPro is excellent, it leaves non-Windows users out in the cold. That’s where Minipro comes in.
3.1 What Is Minipro?
Minipro is an open-source command-line utility for the TL866 family of programmers, including the T48. It was created to give Linux and macOS users access to these devices without relying on Wine or virtual machines.
3.2 Why Use Minipro?
Cross-Platform Works on Linux and macOS.
Scriptable Because it’s CLI-based, you can integrate Minipro into scripts and automation workflows.
Open Source Free to use, and the code is transparent.
3.3 Installing Minipro
On Linux:
sudo apt install git build-essential libusb-1.0-0-dev
git clone https://github.com/DavidGriffith/minipro.git
cd minipro
make
sudo make install
On macOS (with Homebrew):
brew install minipro
3.4 Using Minipro
Example: Writing a binary to a 28C256 EEPROM
minipro -p AT28C256 -w firmware.bin
Example: Reading from a chip
minipro -p AT28C256 -r backup.bin
3.5 Limitations
Not all chips supported — check the minipro -l list before starting.
Firmware updates for the T48 still require XGPro on Windows.
No GUI (unless you use third-party front-ends).
4. Other Options and Workarounds
4.1 Running XGPro Under Wine
Linux and macOS users can run XGPro through Wine. Many report success, especially on Ubuntu, though some UI quirks can occur.
4.2 Virtual Machines
Using VirtualBox, VMware, or Parallels with a Windows installation gives full XGPro support on other operating systems.
4.3 Visual Minipro
A macOS GUI app built on Minipro, available on the Mac App Store. Handy for those who dislike the command line.
5. Choosing the Right Software for Your Workflow
If You… | Recommended Software |
Use Windows daily | XGPro |
Use Linux or macOS and need all chip support | XGPro via Wine/VM |
Use Linux/macOS and only need common EEPROM/Flash | Minipro |
Want scripting automation | Minipro |
6. Troubleshooting Tips
Programmer Not Found
On Windows: Check Device Manager for USB device recognition.
On Linux/macOS: Ensure libusb is installed and you have correct permissions.
Chip Not Supported in Minipro
Fall back to XGPro on Windows.
Or request support from Minipro maintainers.
Write Failures
Check chip orientation.
Verify the chip is blank (use Blank Check).
Ensure proper programming voltage.
7. Real-World Use Cases
Case 1: Retro PC BIOS Programming A hobbyist restoring a 486 PC uses XGPro on Windows to flash a 27C512 EPROM with a BIOS image. The 25 V programming voltage of the T48 ensures compatibility with this older chip.
Case 2: Embedded Developer on Linux An engineer uses Minipro scripts to quickly write test firmware to AT28C256 EEPROMs in a CI/CD pipeline — fully automated without ever opening a GUI.
Case 3: Mac User with Occasional Needs A vintage Mac collector runs XGPro inside Parallels to program GAL chips for old expansion cards.
8. Best Practices for T48 Software Use

Always use the latest firmware for the T48.
Keep backups of all binaries you read.
Double-check chip orientation before programming.
For EPROMs, remember they require UV erasure before rewriting.
Use anti-static precautions when handling chips.
9. Final Recommendation
If you’re on Windows: Use XGPro — it’s the only way to guarantee full support.
If you’re on Linux/macOS: Use Minipro for basic work, but keep a Windows option ready for complex chips.
For automation: Minipro’s CLI is unbeatable.
For maximum reliability: Always verify your writes.
