The whole idea was more trouble than it's worth. If a program really required a physical amiga chipset that UAE can't provide, then the fact the A1200 is plugged into a 600MHz+ PPC machine with 512MiB RAM via a PCI bus, with all of AmigaOS4's bells and whistles.... that same program probably still wont work :-)
If you want to use your old hardware, get a PCI catweasel.
