HI all
first post! ,
I have noticed a few of you guys (at least) have this board, and was hoping someone would be able to help me in my quest.
I have a rev 1.7 VL/I 486V2 version of this.. which as some would know, consists of the GX4 PCB with some bits missing. Peeling the sticker off the board reveals the full GX4 part no. So i am trying to populate the Regulator section, but I am unsure of a couple of components. namely:
R45, R46 , and it seems some boards had the LP2951 regulator + a bypass transistor in U20 /Q4 , whilst others had an LT1085 3 terminal reg in this posiition and no LP2951 fitted. Lastly, the 7404 logic chip. I'm not sure its purpose in this application, but the slightly different Rev 2.0 board I found a pic off shows it fitted.
Not fussed which way I go, but would love to have an example to go off. Any help greatly appreciated!

-Edit.
I have completed the cponversion and since installed an Am5x86 on this board. The modifications and info achive this are documented here:
Thanks for the pic's!
