I picked this Retro Games Commodore Amiga A500 Mini from off eBay for £35..
It was sold as "no power", and it absolutely doesn't turn on... and it does something weird to my power-bank!
Let's try and fix it!
Hope you enjoy!
Steve

WE had the blitz programming language for ours. My son who was about 5 or 6, could make it tell knock knock jokes and drove us all crazy. My daughter loved thomas the tank and played it all the time with that music that just repeated on and on. We survived to tell the tale and so did they. The A500 went as a trade in for an a1200 a few years further on. Happy days when you could still do programming with the kids.

@christo930
@christo930 4 месяца назад
I posted in the main thread the best way to play Pinball Dreams is the GP32. It is so much more intuitive and fun in the handheld format. The flippers are the shoulder buttons, which feels much more natural to pinball. Your thumbs are right there to do English. Britain was one of the few places with an official GP32 release (it was a South Korean handheld). A ton of emulators and homebrews are out for it as well. But the PD game is native and not emulator.

The Zero resistors are not fuses. They are more like jumpers. Since most boards today are populated by a pick and place machine and would cost more to have a person inserting jumpers zero resistors are used.
@samuraidriver4x4
@samuraidriver4x4 4 месяца назад
Adding to that is the cost of a multilayer board with more then 2 layers is more expensive then a couple of zero ohm resistors placed by a pick and place machine. You do still see a bunch of stuff made in china with single layer construction and wire jumpers. Recent Chinese "boombox" teardown from EEVblog comes to mind.

That upper register suits you well for the karaoke sections. Good work finding the blown cap. In general, the tiny ones going from the plus rail to the ground rail are going to be decoupling caps and are nominally 100nF. And incredibly hard to not blow off the board, so good job on that.
@christo930

These things are simply not meant to be repaired. Paying a qualified repairman who would have a lot more overhead would be more expensive than just buying a new or used one. This drives ever smaller parts, since they ain't repairable anyway.

It's one of those cheap Retro Tribute console things, just running an emulator. They're good, but the selection of games is usually a bit low. Most can usually be hacked to add your own ROMS tho, which makes them useful. Sadly, the controllers that come with such tribute machines are utterly awful and almost always use a proprietary connection so you can't use your own. And the descaler is usually pretty junk too.

Ceramic capacitors sometimes only have 20% tolerance, especially as they get smaller. Since the good one measured 120nF then replacing the bad one with 100nF was the right thing to do!
@wryyyy
@wryyyy 4 месяца назад
Wouldn't a 200nF been just as good choice if not better? Excess capacitance isn't after all too huge deal in most applications. Would think a smaller cap could possibly be too weak to supply whatever component that its feeding. Or have I understood this wrong?
@georgeprout42
@georgeprout42 3 месяца назад
@@wryyyy Remember there were 3 capacitors in parallel, hence Steve had to check each one in turn to find the shorted one. The large one is for smoothing (tens or even hundreds of μF) , the smaller ones are for high frequency noise filtering and are pretty much always 100nF.

Thanks for a great channel with great videos! You inspired me to learn and repair my own and others stuff. These SMD capacitors are a pain though with no markings. I have done some research and I believe that the exact value is mostly needed in clockcircuits and motors. In most usercases a higher farad capacitor will still work but lower may be insufficient. In some cases it is still better with lower than original if not exact. I feel that it leaves some room for trial and error if you don't have a complete working unit to measure, or am I wrong? /Much love from Sweden
