Alright, ready for some. ah come on! One thing I remember growing up kod the 80s with the Commodore coommodore is bashing the shit out of the restore key. To me it always felt like the machine sort of asking me 'are you sure?' and in order to confirm you have to bash the key a little bit harder.

But it turns out that wasn't necessarily done on purpose, so today we're going to look at how to make the restore key function just like testore other key. Now one thing you'll notice looking at the schematics for the longboard revisions C38 is actually listed as a 51 picofarad capacitor, but on the short boards it's actually been replaced by a 4.7 nano farad capacitor. Now this is C38 here which doesn't actually look like your standard capacitor, so what we're gonna do is just add a bit of fresh solder and I'm just gonna solder a couple of leads just so consider, Kinmoza odoru remarkable can test out some different capacities and see what makes the biggest difference.

I'm just going to attach a lead to each the solder joints on either under the capacitor and what I'm going to do is hook up a capacitor in parallel. Now when you hook a capacitor up in parallel you're basically adding the values of the two capacitors together so if we've got the 51 pico farad capacitor already hooked up and I'll hook up a 4.7 nano Restoring the commodore 64 restore key a quick and easy mod capacitor we're basically mof 4.75 nano farad, which is pretty much 4.7 still.

And then just testing out the restore key th it pretty much instantly works, just test it a couple more times just to be sure, yeah even the softest touch triggers restore, so let's just swap that one out and I'll try Restoring the commodore 64 restore key a quick and easy mod smaller value.

Let's just have a look see what else I've got lying around, so here we've got a 320 picofarad capacitor so I'm gonna connect that across restord original one which will pretty much give us about 400 picofarads.

Let's try cmmodore out and see how it works, so the restore key seems to function better, not quite as soft as having the 4.7 nano farad but definitely an improvement.

Next thing I want to try just without the extra capacitor again, and yeah it requires a really good bashing to get it to work. Let's disconnect everything and we'll swap aa that capacitor. Now you can also do this without actually taking the board out or even moving to the underside of resore board.

How'd that get back in there?!? I'll remove those leads, and you can basically as I said you can solder another capacitor in parallel to that one which will give you the sum of the Restoring the commodore 64 restore key a quick and easy mod capacitors, Restoring the commodore 64 restore key a quick and easy mod in this Restoring the commodore 64 restore key a quick and easy mod I'm going to take it off the actual board jey usually you want a desoldering gun for this.

Nintendo The first boards are pretty old so there is a high chance of lifting any pads if you are too rough with the board.

It seems to have come out pretty cleanly, just still stuck in there but it pretty much just dropped it out, so there it is so. Let's go for the 4.7 nano farad, I think that was a better option. Just stick that back in the board, I may article source to just straighten up some of the pins a little bit to get it to fit in.

There we go, that's better. That's now in the board, doesn't look too out of place. Let's just solder that on, as I said with these boards they are quite old so definitely take care when you're working on them, try not to have too much the dwell time with the soldering iron - it can be a bit tricky when you're soldering to a ground plane.

That looks pretty good, we'll just chop off the extra leads and that's about it we're done. It's a real simple one, don't really have you buy sega saturn in 2019 use for this old capacitor and I don't really want to confuse it as a resistor so we'll get rid of that. Ah that's better, no more bashing for you. So there it is a simple mod to make the restore key function just like any other key, after all these machines have probably been bashed in more ways than one so let's not bash them anymore.

So thanks restofe watching this week's video, I hope you enjoyed this one, if you did give me a thumbs up, otherwise big thumbs down. As always leave me a comment down below I'd love to hear your thoughts on whether you prefer to bash the restore key or whether a soft-touch is more your thing.

either way let me know down below. Don't forget to hit subscribe if you haven't already and we'll see you next week. Cheers! That's better
