Got my Amiga 500 work ? :)

[CrazyBoss]

Hi

 

Just pulled out a Amiga500, which I owned since 2001, I replaced the diskdrive back in 2001, and got a Alpha+ harddisk interface, which can have 8mb ram installed. I did that too. I put in a 628mb drive that time. Also got a new (also in 2001) external drive.

 

But something is not right

 

When I first boot the computer it flashed screen and some weird lines in the top of a black screen.

Some times i got the insert disk kickstart picture, flashing.

 

Both with RGB cable and Composite cable.

 

Then I took apart the computer and took the shield away and used some electronic cleaner to clean sockets and put back it chips. And then it worked good for a few hours. Then the next day and put everything back in case, and turned it on again, same problem. So I took everything apart again and messed around with the mainboard, and suddenly i had picture again.

 

Anyone know what it could be, caps on board looks good, mainboard looks good.

 

But I have to say my floppies dont look good, i tried 5-10 diskettes, all failed. Not a single i tried could be formated.

 

Tried to clean the drive - helped a bit but still could not format a disk.

 

I wish amiga had used another format than 880kb for a floppy. Keep to 720kb had then I am sure more diskettes could be read, to compare, I did not have problems with my MSX diskettes which is also 3.5" 720kb (same format as PC uses).

 

And even the Commodore 64 diskettes even they are from the start of the 80's they still can be read

 

I am running kickstart 1.3, if i find a floppy that works, is there a way to install the game on my harddrive ?

 

Thanks

You should probably look at an sd floppy emulator with amiga modified firmware.

Intermittent functionality is often related to one or more cold solder joints. It would help to clean the whole motherboard with abundant CRC and then resolder as many connections as possible.

 

Are voltages okay?
