Thema: Re: N51SX(8551) SIMM?? Datum: 18.09.97 03:45:23 From: bwigg@worldnet.att.net (Billy Wiggins) To: Peterwendt@aol.com Peter, I would be happy for you to add it to your site. All I did was use a standard 72 pin 2MB 512K x 36 PNY SIMM and add the jumpers to it and wound up with the gnd on 68 and 70. I also clipped the plastic tab on SIMM socket. (Like that was gonna stop a true hacker) I don't think I could make up a schematic with my mailer. What's your pages address I would like to see it.

So - while just being busy on reworking my pages, I tried to picture Billys modification on the 2MB-module. It will probably be not exactly how his module looks like - but show the principle. A diagram of the module:

In case Billy manages to rework a 4MB- or 8MB-module, the results will be published here as well. |
