I now have received the TF534 and a relocator/kickstart adapter. So I opened up the Amiga. Last time I did that was 15 years ago. Still there was a big surprise. This machine is not a orginal PAL computer, but a to PAL converted NTSC machine!

There have been a few modifications to enable it as a PAL machine:

There is a small PCB on the right which function is unknown to me but might have to do with the PAL conversion. The same is true for the wiring with quartz and two potmeters on the left. Anyone who can shed light on this is invited to make a comment.

Then there is a RAM modification:

There are several ram-chips stacked on top of each other. I will try to find out later how this probable ram-expansion is achieved.

I am now trying to clean up the cabling of the NTSC modification and make it disconnectable.

Stay tuned for the next part.

The small PCB is part of the RAM modification. Because the Amiga wouldn't start after I modified the cabling, I removed the complete RAM expansion modification. It now has 256kB and an original expansion in the front slot of 256kB and works fine.

I still own the NTSC A1000 that I bought back in 1985, complete with matching A1080 monitor. Converting it to PAL was a matter of swapping out the Agnus and replacing the oscillator block inside the shielded box with the perforated lid. Other than the NTSC to PAL conversion, I'd restore the board back to its original state as much as possible and get rid of all the flaky wiring and extensions. The A1000 may be lacking performance and is rather upgrade unfriendly, but why bother? After all, it is the mother of all Amigas. If you want computing power without having to sacrifice the beautiful A1000 case, consider getting a GBA1000 with PicassoII GraKa and 68060 turbo card.
