Since Ive gotten my vintage macs out, Ive thought of building an AppleTalk Network that works with all my 68k Macs

This is what I have so far

Original Mac SE 2.5MB RAM 20MB HD

Mac LC 4/40

Mac SE FDHD 4/20

Mac Classic II

How does apple talk work with System 6, can file sharing happen between System 6-9 macs. I would also like them to be able to print to my HP Color LaserJet 4500 that is AppleTalk Compatible.

What hardware should I use and software
