I've got a 5400/180 (which used to be a 5200 but I upgraded it with a 6400 motherboard), and a PowerMac 4400/200. The 5400 runs OS 9.1 and the 4400 has both OS 8.1 and BeOS 4 installed. Currently they're both sitting under a desk not getting used but I would really like to get them set up again as they're both great machines.
The 5400 was an upgrade project of mine a few years ago and for a while was my main computer, with the full 128MB RAM, L2 cache, 4GB hard drive and a video in card.
Go for a 6500's board - that will show you millions at 832x624 or thousands at 1024x768 but tiny icons. Or this monitor's standard 640x480 which I prefer because the TV window is limited to that size.
My concern is why neither a 5400's board nor a 6500's do work together with the 5200's TV card ?
I found out - the A/V-card is the reason. BTW, the 5500 can get an easy install of 9.0 by using original installer CDs designed for a G4 - both have ATI-graphics (the 5500 as onboard). And these Performa/PPCs have the capability of recording radio to audiofiles (one hour is about 100 megs only - got a 40GB in that) as well as videorecording in small windows - what a marvellous computer ! And I got two in short succession (a 225 was instantly upgraded to 275 MHz). WOW !
I will present better photos on my page some other day,
My everyday computer is a 5400/180 with everything. 19,4GB maxtor HD, 136 MB, L2 256k, USB 2slot, TV, external video card, built-in but external zip (connected via USB), an external burner (Teac CD-R56S4), external HD (Conner CFP 4207S 4.28GB), iomega jaz 2GB, Syquest 200MB and Microtek ScanMaker II. Two keyboards (Apple Keyboard II, Apple Design Keyboard, Wacom ArtPad. The external 17"-monitor is shared with a G3/233 or a (sorry for this) PC. 4-way stereo-system. This runs 9.1 or 8.6 (just take the Finder out of the sytem folder. put the other system's folder bach - open the folder once, so it gets the active-system's icon and restart). In my other room is a black 5200/75 (64 MB, 1.6GB) as a TV running 8.5.1. There are two other boards for this one to turn it into a 5400/180 (136MB, 8.6 on 9GB then) or a 5500/275 (128 MB, 9.1 on 10GB) with a 4-slot USB-card.
And I have four PowerBooks 1400; 1400c/1400cs/1400cs/133 and 1400c/166. Just bought a power supply for €1 (Euro) seconds ago.
