Thanks for this riser @go0se I ordered a batch of 4 layer ones from JLC, and they arrived a few days ago, really work very well in my A500+. Really like how the ide port lines up perfectly with the expansion port exit. Have tried with a lot of different software, no problems at all :thumbup:
Glad it's working well for you @Danoo and good choice going for the four layer version! I've been using them for a while and they seem pretty solid. The expansion port alignment was kind of a fluke. :)

Make sure you clip back the underside of the D5-D12 receptacles that sit above the Agnus and apply some tape underneath to prevent any issues.

Yes I did noticed that possibility before I powered up, already have a couple of strips of electrical tape on the underside terminal connections above the Agnus :thumbup:

Ah great stuff, I've been wanting rom clearance there for ages.
Not on rev5 motherboard though (the most common one). But it doesn't matter really, I always thought kickstart switchers are useless.

The revision5 A500 ROM layout feels like it has been deliberately designed to thwart any attempt to fit a TF536. I did intend to come back to it and see if I could produce something REV5 specific that what a lot more satisfactory, but I got distracted.

I encounter a lot more 6A and 8As, but that's just based on a sample of me. Perhaps the 5 is more prevalent in North America.

Yeah, about 90% of A500s I encounter here are rev5s. Very rarely I see a rev6 and I don't think the rev8 was ever released here.

This relocator looks great. Clearance on Rev 5 would be good for adding EEPROM adapters for those who can't or won't modify the motherboard itself for EEPROM compatibility.
