Got round to replacing the regulator in my project Speccy today with a RECOM R-785.0 DC-DC Converter. I couldn't get any pics of the actual replacement in progress owing to me not having 3rd or 4th arms, but it was straightforward and mercifully free from problems.

If anything was going to go wrong then I have a few 7805's in my spares collection, so I took a pair of snips and cropped the leads of the old regulator, having first unbolted the heatsink from the mainboard. After binning the legless 7805, I warmed the joints holding it's remains one by one with my soldering iron and pulled the legs out with a pair of pliers, then cleared the holes with the solder sucker ready for the new component. 3 solder joints later the deed was done and I wiped the sweat from my brow, grabbed my PSU and gritted my teeth - Success!
Still no keyboard though... :)
I also performed this mod that I found on
Sami Vehmaa's old site, it's meant to improve video quality by fixing some ghosting issues - on my (4A) Speccy it did nothing discernable. Perhaps I might perform the other video fix on his site at a later date and see if there are any notable gains from that.
