ok, fist of all WOW! 20K?

? You have some good machines there although only one is AGA. The CD32 Has the best BASIC graphics Chip set but is the WORST at upgrading. They do exist if you can find them. If you can find one, get a SX-32 and an exteranal Ficker Fixer.
Thats the easy one.
For the big box Amigas, could you list what you have already installed? Then every one here will be able to give you MORE then enough advice :elvis:
