Those that know me will think I'm in way over my head on this. I might agree with them, but I'd like to try. Since I can't find anything on the 'net, I'm toying with the idea of building a RAM tester. Specifically, I'd like to start with a 4116 tester. Heck I figure if I can get that to work, it should be a snap to test other types of RAM. I recall someone on this list from South America (Brazil?) was attempting the same project but sadly we never heard from him again. I admit up front, I have no background in this type of stuff, but I do have a willingness to try. My long range general idea so far is to have a fairly large breadboard with 25 ZIF sockets on it. From there, wire the appropriate voltage pins to a common point so I can supply power via a switching power supply. That in itself is probably enough of a challenge for me, but assuming I can do that (and that's a pretty big assumption), then what? I'd like to have it interface with a PC to run a program to test the RAMs at various speeds. I know pretty vague, but that's where I'm looking for your input. Thoughts? Ideas? Advice? Any comments appreciated.

Are these DRAM's? If they are I would bet that you will need to put the DRAM controller on-board to handle the refresh. Not only this, but the refresh rate would have to be customizeable to handle the different types of RAMs that you're testing. -Adam On Thu, 17 Feb 2005 14:05:51 -0600, joemagiera <joemagiera@ameritech.net> wrote:
