Playing with an IBM iSeries (AS/400)

I picked up an old (2000 ish) AS/400 a while ago but never could do anything with it as I had no keyboard for the terminal. Finally found a cheap keyboard so let's have a play with it!
Looks like it might have once belonged to Waterstones!

Bit of an epic length this one so here's time stamps:

00:00 Intro and look at the rear of the chassis
04:40 Look inside
12:52 Look at the front (Drives)
17:00 Look at the InfoWindow terminal
19:11 Power on the terminal
21:33 Power on the iSeries
24:28 Error on boot diagnosis
26:11 D'oh! Boot attempt 2
29:17 It's alive - something appears on the terminal! News isn't great though
30:54 Logon prompt! What's the username/password?
32:19 It's up and running! Exploring the operating system and users
35:40 Playing around with the web servers
38:18 File browsing
39:00 Full power on sequence (sped up 20x!)
39:53 Logon screen
40:19 Look at network stats/services
40:58 Still starting services
41:50 Overall thoughts and ramble
