A C64 Repair with a twist!
Trying to pin down the fault in this Commodore 64 using nothing but the power of my mind and a workbench full of tools. Also the internet. And experts I can ask for advice. Apart from those things, just the power of My Mind! And my eyes. Those helped too. Completing the repair of this C64 first seen in the Topdon thermal camera episode.

Another C64 saved! I'm interested in seeing case clean ups. Always interesting to see people's methods and very satisfying to see a before and after.

@MoreFunMakingIt Год назад

I'll throw a cleanup in occasionally when it's interesting. Just for you 😉

@TheRetroChannel Год назад

Nice work. I'd recommend also running the SID tester program by Andrew Challis, it can reveal issues that the regular diagnostic test will not. Also the police are on their way

@MoreFunMakingIt Год назад

I'll look that up! Have a marginal SID here I can try that with. They'll never take me alive!

Hey buddy! Been really enjoying these C64 repair videos of late. Really entertaining and always great to see another one resurrected by your good self. So many great tips being picked up along the way. Superb stuff mate. Have a great weekend 🤟👍😎🍺🏴󠁧󠁢󠁳󠁣󠁴󠁿

@MoreFunMakingIt Год назад

Thanks Stewie! Loads more to come!

@CurtisOvard Год назад

Another good one Lee, I introduced my 13 year old to retro repairs.

@MoreFunMakingIt Год назад

That's wonderful Curtis! Would love to know how that went.

@CurtisOvard Год назад

@@MoreFunMakingIt He was just in awe at how big everything was and how little storage was. It was funny when I handed him my 1541. I was watching this and an LGR 386 computer and he started asking what was going on so I broke out some of my stuff.

@MoreFunMakingIt Год назад

@@CurtisOvard That's so cool. Great that he's taken an interest and amazing he has you to show him how things used to work!

Glad I bought a memory chip tester as I'm having the same multiple issues with the 7 Speccies and 7 C64s I have to work on (collect them for some reason), so a good, relevant video for me

@MoreFunMakingIt Год назад

That sounds like the start of an epic journey, and possibly the title of a musical 😁 Good luck!

@miguelrios4602 Год назад

Thanks for the video. I appreciate it. Can’t tell you what I am learning, but I’m learning something 😊 Again, thanks!

@MoreFunMakingIt Год назад

Learn something random every day! Welcome 😁

@RudysRetroIntel Год назад

Great job on the repair!! After working in many C64 myself, I have found that the dead test memory flashes are a hit and miss. The more you fix them, the faster you repair them. Thanks for sharing

@MoreFunMakingIt Год назад

Thanks Rudy! It's starting to be unusual whether dead test gets it right!

@ghost-retro3733 Год назад

Good fix!

@stevesgaming7475 Год назад

15 seconds in and I said "U24 is faulty" ..you believe me ..right? ;) (great video as always, thanks!)

@MoreFunMakingIt Год назад

I believe!

@Breakfast_of_Champions Год назад

Nice. The rusty one I thought was suspect as whatever liquid might have creeped inside?

@MoreFunMakingIt Год назад

It's not so much the liquid gets inside, although I'm sure that could happen, rather than the legs corrode and that works it's way inside. I was sure it was going to be faulty!

@michaelcarey Год назад

Great video! I can't get enough diagnostic videos like this, well done. I am wondering about the RAM tester seen at 07:57. Can you tell me where to find more information about this device?

@MoreFunMakingIt Год назад

Thank you Michael! The ram tester I bought from a seller on ebay - www.ebay.co.uk/usr/analog-kid?_trksid=p2047675.m3561.l2559 They do a range of different ones. Hope that helps!

@user-wk5pq7et3d Год назад

Отличный метод ремонта - подкинуть монетку :-) Надо взять на вооружение!

@MoreFunMakingIt Год назад

It worked so it must be good! 😁

@wimwiddershins Год назад

Always trust in the washer of fate.

@MoreFunMakingIt Год назад

The Washer of Fate is now a permanent tool in my workbench.

@CallousCoder Год назад

Word... no father... Euhm so you are trying to say “you orphan”? Sorry for my ignorance Lee, English is only my second language ;) Awesome video as usual, great relaxation after a stressy morning my retro friend! MFMI does that stand for m*ther f*cking machine inspector? :P

@MoreFunMakingIt Год назад

You got the first two words right 😆 the second two are interchangeable depending on what I've broken
