Re: Nvram
just compare the stock eprom pinouts and the nvram pinouts and make them match, and add the write line to the extra pin on the socket. You might find you have problems with random corruption without proper buffering and power filtering, but it has been known to work. Also know that most or all the cheap nvrams on ebay are clones and also prone to trouble. If you go that way its probably worth buying a couple so you can swap if you have problems with one. Also have a read of this at a lot of it applies to low cost home brew, even if your not buying someone elses hack job. http://pcmhacking.net/forums/viewtopic.php?f=7&t=2685

While not complete in terms of board layout or full schematic, the basic idea to build your own is here .. http://pcmhacking.net/forums/viewtopic. ... ematic#p97
