I bought this unit because the T48 programmer I have can't properly program older 27 series EPROMs without falling on its face due to not having sufficient write current and failing to burn the EPROMs. That isn't an issue with the GQ 4x v4, it has the option for an external 9v supply that gives it the needed current to burn old 27 series EPROMs. Specifically I needed to be able to burn a faster 27c1024 for an old IBM PS/1 Model 2133-C11 for overclocking the system. It worked first time with no issues. Review: Great Hardware, Okay Software - This programmer works great and can handle a very wide range of devices. I chose this one because it was the only programmer I could find known to program a particular device I needed. The hardware feels very sturdy and high quality. The software is relatively easy to use but feels "old school" and a little clunky, like it was made for Windows 98. The GUI doesn't quite format right under Windows 10, so certain elements like progress bars get cut-off at the edges, the info button is super narrow, etc. This doesn't hinder operation, just looks weird. I had no trouble installing the software and drivers and was up and running in less than 10 minutes. ## Features - GQ-4X programmer hardware and software are developed/designed by MCUmall Electronics Inc Canada - True USB willem and GQ are the registered trade-marks of GQ/MCUmall USA - This exclusive package is perfect for backing up slot machine game collection - Post-sales/Pre-sales technical support forum from MCUmall Canada website - Free software upgrade life-time & Multi-languages support capability: 14 languages ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01212KD74 | | Best Sellers Rank | #9,627 in USB Cables | | Brand | GQ | | Color | white | | Compatible Devices | All compatible adapters, POSOP44, PSOP56, TSOP48,TSOP40,TSOP40,TSOP32,SOIC,PLCC84,PLCC44,PLCC32,FWH+16bit EPROM, AVR Compatible Devices All compatible adapters, POSOP44, PSOP56, TSOP48,TSOP40,TSOP40,TSOP32,SOIC,PLCC84,PLCC44,PLCC32,FWH+16bit EPROM, AVR See more | | Connector Type | usb | | Current Rating | 1 Amps | | Customer Reviews | 4.6 out of 5 stars 139 Reviews | | Finish | Matte | | Input Voltage | 5 Volts (DC) | | Item Dimensions | 1.97 x 6.69 x 88.19 inches | | Item Weight | 0.41 Kilograms | | Item dimensions L x W x H | 1.97 x 6.69 x 88.19 inches | | Manufacturer | GQ Electronics LLC | | Mfr Part Number | PRG-112 | | Model Number | PRG-112 | | Nominal Power | 5 Watts | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Gambling | | UPC | 723794244879 723794244602 | | Unit Count | 1.0 Count | | Warranty Type | Limited | ## Product Details - **Color:** white - **Connector Type:** usb - **Item dimensions L x W x H:** 1.97 x 6.69 x 88.19 inches - **Specific Uses For Product:** Gambling ## Images ![GQ Brand GQ-4X4 USB Universal 40 pin Programmer + 16 bit EPROM Adapter 28F102 27C400 27C800 27C160 27C322 27C1024 27C2048 27C4096 27c4002 M27C322 Programmer - Image 1](https://m.media-amazon.com/images/I/418mn0Q8PeL.jpg) ![GQ Brand GQ-4X4 USB Universal 40 pin Programmer + 16 bit EPROM Adapter 28F102 27C400 27C800 27C160 27C322 27C1024 27C2048 27C4096 27c4002 M27C322 Programmer - Image 2](https://m.media-amazon.com/images/I/41xt9rP3aoL.jpg) ![GQ Brand GQ-4X4 USB Universal 40 pin Programmer + 16 bit EPROM Adapter 28F102 27C400 27C800 27C160 27C322 27C1024 27C2048 27C4096 27c4002 M27C322 Programmer - Image 3](https://m.media-amazon.com/images/I/41fDpSwnrJL.jpg) ## Questions & Answers **Q: What is the max VPP voltage?** A: Sorry, I ended up returning it, as rather than myself, I had a local place program car ECU than myself. **Q: Can i use to make snes, nes and n64 roms?** A: You can use this to program snes and nes eproms (using the 27c line of eproms), but not n64. **Q: Can this program single-shot proms in addition to eproms?** A: Yes, OTP devices can be programmed. I suggest perusing the supported device list to see if your required device is listed. **Q: Does this work with Windows XP 32-bit?** A: The drivers and main program does work on 32-bit XP ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great EPROM/EEPROM burner. *by F***O on May 18, 2025* Great all around EPROM/EEPROM programmer.
