You might be in luck. You can go back in TIME. With the Real deal thing.
I have one of these. UNITECH (original) 2 ROM Switchers. Like NEW.
https://bboah.com/index.php?action=artikel&cat=62&id=2644&artlang=enI bought it last year on Ebay(Australia) for my A2000 Restore project.
I was going to convert it to work off a ribbon cable to move it over, and also to make one ROM socket a Zip SOcket to flip my other Kickstart ROM manually.
Using a few parts I also acquired as shown below. (To make a ribbon cable extender, to snap the Unitech into it, and then ribbon cable pins into Amiga Socket)
But I came across a real Cool Drum Machine ROM Switcher, that does 4 ROMs, and Exactly what I needed.
The one I got (shown installed and working above) is different but similar to one of these
http://musictechnologiesgroup.com/blog/?p=54Mine is NOT an electronic switch (like in the link), but a TURN Mechanical Switch (that actually works with Amiga)
The UNITECH orginal Amiga Switcher is like brand new (work 100% for two ROM), and I might be interested in selling all the parts if anyone is interested.
Soldering would be required since I didn't finish the project. (NO soldering required on the Unitech. Just soldering required to make the extender, or get a Male-to-Male Socket ribbon extender [which I tried to find, but they don't make anymore].
Once extender is made the Unitech would snap in, and the other end into the Amiga ROM socket.
I could finish the Ribbron-Cable-Extender build but then price would go significantly up, and Not sure I have the time.
I'm an electronic Engineer and to Copy one of these Unitechs would be a challenge to make the Circuit board (also illegal too). And the CHIP is not marked anyway which is also needed to understand how the Flip works.
