You¡¯re getting the wrong end of the stick John. There are gizmos to buy out there but the problem us software is not 64 bit. At least Geniatech has had a go.
It¡¯s the software is the critical thing not the hardware. No use looking at things that require scart- there¡¯s no scart inlets on the back of a Mac.
Who on earth wants to record to an iPad - watch maybe.... but then what. IPads only run cut down versions of any software.
Maybe we just have to come to grips with technology galloping and keep old Macs going for old stuff we like and want to use. I don¡¯t know for sure but I think the newer systems not friendly to partitioning drives to run old systems any more.
