I was lucky to receive an Amiga 2000 for my birthday. It doesn't work however, but not to worry, that just makes it more fun! In this video we're going to take a look at it, understand a little about it, and attempt to fix the fault. Spoiler: Surprisingly, it wasn't the battery! And I don't think that was the original either.

Good fixes, great to see another A2000 rescued! One thing - might be worth neutralising any residual battery acid on the board with vinegar and clean off with IPA ;-)

Thanks - already did prior to the video

@johnybitmap2559 6 месяцев назад

Well, happy B'day Rob! As someone having an A2000 myself, the look inside was very familiar. Also had to de-solder and extract the clock battery which I found burst-opened and leaked on the board. Are you planning to do some extra tweaking and hacking? Like adding an HDD and/or a CD/DVD-ROM into it? (if possible of course - but I guess that's why the dedicated ISA slots, and the unused space which can be seen from the front of the case, are there in the first place, aren't they?)

I have my original Amiga 2000 still from 1991 and the keyboard that came with it is the same as yours with just Commodore Amiga written on it.

by "had", do you mean that you unfortunatly dont have them anymore!?

@mikedefoy Месяц назад

@@RobSmithDev I sold everything before 2000 on ebay. In today's dollars, one machine (of the 3) is roughly estimated at $40K. There were no open slots anywhere, all available expansion options were installed on the motherboard. My Top10 music was created on the Amiga using Bars&Pipes, Dr. T's, etc.

@RobSmithDev Месяц назад

A shame, but something that the majority (I think) of Amiga owners did around that time, and something that was regretted a lot not. Awesome that you created Top10 music on the Amiga!

very good video, the amiga 2000 was a very good machine at the time I also have a well upgraded 2000 with a bluescsi v2 card 😄

@markokonigschulte7551 5 месяцев назад

Great video, thank you! Watching it I wondered if you could replace a defectice disk drive with a drive scraped from a 500. You`d keep the metal housing and plastic front cover/button and swap the drive. Aside from the railing that holds the ejection button they are identical, aren't they?

@RobSmithDev 5 месяцев назад

The A2000 drives have an in-use led indicator that’s missing on the A500 drive. Technically it would work perfectly but aesthetically it wouldn’t be a good match. Luckily they both work perfectly after cleaning!

Great fix, lucky you getting a 2000 for your birthday. i got a 1200 for xmas couple of years ago and broke it, got a second and that doesnt work properly either. :( now have two sick 1200 's.

@hackbuildrestore 6 месяцев назад

Excellent video! I found myself wondering if the RGB power issue is a common fault, I discovered the same fault in mine, if it's not common then the odds of it occurring on two A2000 Rev 6 boards on RU-vid in the same week; doesn't bear thinking about!

@RobSmithDev 6 месяцев назад

From what I’ve understood the fuses are easy to blow so might be fairly common. If they blow again I’m going to swap with PTC resettable fuses instead. The track that was blown though, not sure how that would have happened.

@hackbuildrestore 6 месяцев назад

@@RobSmithDev neither am I, but it's happened on at least 2 boards (we know of lol), I originally thought it could be because mine didn't have a bottom shield and at some point it had a short caused by something rolling around in the case (screw or similar), but I think yours had a shield... so, I really don't know now :)

@RobSmithDev 6 месяцев назад

I'd heard about static discharge causing it, and I have a theory for the 5V line. Either somehow it shorted against the shield, or maybe if you had the right 23-way cable, maybe if you tried to plug it into the back of an external floppy drive that woud connect 12v (on the floppy drive) to 5v. but thats a real long shot

@@RobSmithDev at the CBM dealership I worked at with another Lightwave enthusiast Dan Ablan, I think we removed some motherboard screws for that very reason, if memory serves.

@MichalBergseth-AmitopiaTV 6 месяцев назад

Nope. My Amiga 2000 is from 1986. Made in West Germany. So, it is not from 1987.

@RobSmithDev 6 месяцев назад

That’s what Wikipedia said. Maybe they were producing them as stock and released them in 1987? Or did you have it in 1986?

@MichalBergseth-AmitopiaTV 6 месяцев назад

@@RobSmithDev it is Rev 4 Amiga 2000. Its motherboard is based on an Amiga 1000 motherboard etc. The CPU slot is just an FPU/MMU slot etc but it does have a Zorro II slot. So, Wikipedia is actually wrong. Not many Rev 4 were produced though, but I got it last year. Also, because it is a Rev 4. I was worried that PiStorm wouldn't work on it. But after taking it with me to Amiga38 in Germany. The PiStorm team figured it out. I needed a Longer firmware for the PiStorm to work as my A2000 uses 68000 slot signals all over the motherboard. So, now I use it as an RTG Amiga. Love it.
