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
