Vetus Pars Retro IC Tester is a modern, standalone hardware platform designed for anyone who repairs, restores, or collects vintage electronics. Whether you're working on old computers, arcade boards, synthesizers, audio gear, or test equipment, the Vetus Pars provides a fast and reliable way to evaluate logic chips, DRAMs, SRAMs, CPUs, and custom devices. Vetus Pars includes its own color LCD, navigation interface, and menu system. With just three navigation buttons (Back, OK, Down), you can browse chip categories, search by letter, load stored tests, and run diagnostics without needing a computer. For creators, technicians, or engineers, the Vetus Pars also acts as a programmable testbench. Test routines are written in a simple human-readable text format and uploaded through the Vetus GUI. The onboard STM32 processor compiles them into fast, low-latency microcode, allowing near-instant signal toggling and accurate vintage chip timing. Its 40-pin ZIF socket and clean 5V-regulated power system make it compatible with a wide range of ICs. The optional “Fan Control” header provides 3.3V + GND for cooling or accessories if needed. For firmware updates, the Boot0 button allows direct DFU mode simply by holding Boot0 and power-cycling the device. Whether you're a hobbyist or a professional technician, Vetus Pars brings modern speed and precision to vintage chip testing — in a compact, reliable, and fully user-programmable package.
