Review on 🔌 PRG-056 MCUmall GQ-4X V4 True USB Universal Chip Programmer: EPROM Flash, PIC BIOS, AVR - Full Pack (Canada Made, GQ Brand) by Michael Welborn

According to other reviews, the program is easy to use. It programs chips that are not in the list, just choose a similar one (look at the chip's properties before trying, for example: is it the same Vpp?). Intel AD28F256-200P1C2 is not listed. Selected Advanced Micro 28F256. The software complained about the device code, but programmed it anyway. 9V power supply not included. It's only needed if you're connecting it to a non-powered USB hub. There are cheaper programmers. I wanted something SIMPLE to use. Looks like I got it.
