Why??
Why you have 123 amigas, you can't possibly play all of them??
I have sold only one Amiga in my life time and regret it a lot. BUT some years ago I realised that I have 12 A500 Computers, so I gave them a way for those who wanted to have one.
All my Amigas has pimped, lattest roms, Hard drives, Accelerators, etc. Al my 8bit Computers has a modern mass storage solutions, most of them has chips moved to sockets and I have paid to people to do that.
I play ALL my Computers, if I don't I just swap or give it away.
