The Ramcheck itself is a fairly simple device. On the top we have the 168-pin Yamichi socket for testing SDRAM, and the Module expansion ports just below. On the next page of this review we will talk a little about he SODIMM 144 module which simple locks into those expansion ports. Other controls of importance are the six buttons on the right hand side. They are used for navigation of the menu system. Rounding out the three activity LED's there is the LCD screen and power button.

The side of the unit features another expansion port, and on the opposite side a printer and serial port.

One of the more interesting aspects of the Ramcheck is that it is built with a mind towards upgradeability and so each of the main sections are compartmentalized. Besides the fact that this little device is running on a 486 processor it is worth noting that much of this unit is compatible with the older SIMcheck, so owners of that device could actually upgrade the machine.

The DIMMCheck 144 is an expansion module which fits onto the adaptor points of the main unit. Since the Ramcheck ships with a 168-pin socket only there has to be another way of testing different types of memory. This adaptor was the solution, and in addition to the 144-pin socket for SODimm modules there are also adaptors for 100-pin laser printer DIMMs, individual TSOP memory chips, 200-pin FPM/EDO DIMM's, and 88-pin DRAM cards. Last but not least, is the just announced module for testing 184-pin DDR DRAM.
