Woah! That is awesome, and I have a 8272A or two sitting around. The A600 
I have has 1MB of RAM total as it is and I don't have any burning need to 
go above that.

Problem though. The Amiga 600 8275 is a surface mount device, not through 
hole. So no way to mount that easily.

A vendor in Germany has a bunch of 8275 NTSC chips but they pulled them 
off the for sale list as they are turning them into some kind of 2MB RAM 
add on for Amigas. A vendor in UK has boards that run like $40-45 that 
give you 4MB, not sure if it is the same type of RAM (that chip or fast or 
whatever) but it definitely gets in the way of sourcing repair parts.
