My iBook-G3

I just finished setting up my Retro gaming iBook G3 with dual boot MacOS 9.2.2 and OSX 10.4

It is a 900mhz PPC G3 with 600mb ram.

It has a 27gb. Hard drive which I partitioned in half with 2 ( 13gb. ) partitions.

One for 9.2.2 and the other for 10.4

Everything appears to be working fine.

Wifi-N works fine with my ISP WiFi-ac router ( backward compatible with Wifi-N )

iSight webcam works fine.

Ethernet port also works fine and DVD.

Using Apple mighty mouse.

I am using a Lexmark Network printer that is supported in MacOS 9x thru Sierra

The Lexmark E360dn

My questions are:

1) Does anyone know of a good Color network printer that is compatible with MacOS 9x ?

2) Is 600mb enough to play games?

3) What are some good retro games ?
