This is a clone of the famous Kupke Golem RAM Box for Commodore Amiga 1000.

The Kupke Golem RAM Box was very expensive at the time but it was also one of the few memory expansions with a pass through for the Commodore Amiga 1000.

• GQ-4X GQ-3X | WILLEM ADAPTER MCS-51 / AVR + PLCC44

My personal considerations:

This is a great programmer and certainly more stable of the classic Willem (parallel or usb). I have tried to program some EPROM and FLASH without problems. The power supply via USB is very stable and accurate.

from the homepage of MCUmall:

• Support O/S XP 32bit, XP 64bit, Vista 32bit,Vista 64bit, Windows7 32bit/64bit.
• Real True USB interface for both data transfer and power supply.
• High speed/fastest; most-user-friendly; simplest-to-use.
• Software update regularly; free life-time software upgrade/download.
• Multi-languages support capability: Chinese, Czeh, English, French, German, Spanish, Portugues, Italian.

The application-oriented & application-enhanced design facilitates GQ-4X supports thousands of most popular application devices (growing) and ideally suits the portable/convenient applications that includes: car automative field ECU chiptuning, airbag reset, mileage, satilite devices, BIOS refreshing, motherboard BIOS in-circuit upgrade, xBox,Wii gaming machines EPROM duplicate, Altera Xilinx JTAG, PIC/MCU development, newer laptop technology and newer desktop PC etc.

It has outstanding performance which supoprts the devices that other similar products are not capable of supporting: such as 25LF SPI series, PSOP44,TSOP48, 25VF SPI series, Altera Xilinx CPLD JTAG, PLCC84,SST39VF3201, TE28F102, 27C1024, 27C1028,HD6475,29F800, 29LV800, 29F032…
