Amiga 1200 rom switcher

Hi,
I've been looking (without success) for an Amiga 1200 quad ROM switcher schematic or PCB, with 2x 27c160.

Anyone knows one?

Thanks

I did one https://www.exxoshost.co.uk/forum/vi...hp?f=44&t=2018


I was going to make some more but I am struggling to buy the parts due to the global chip shortage

Hi thanks for your reply, by the looks of it, it's not meant for the Amiga 1200.

Could I be wrong here?

Yes it works perfectly in an A1200. You fit 2 one for each ROM.

It must have its advantages, but I was looking for a simpler design like this one:

That looks cool, I would definately be interested in buying one for an A1200 whenever they become available again.

Should be pretty soon. I managed to secure some of the microcontrollers and they were delivered today. I've ordered the other bits I need too now.
