IBM Mainframe Episode III Jumpers, OCAs and AMDs - more inspection, more corrosion

Join me in this video to continue the restoration of the IBM mainframe that I bought in the first episode. In this video we will focus on reassembling the SSA drives we took apart in episode II and we'll continue ahead by cracking open the power supplies aka. OCAs and the fans aka. AMDs to see what the situation is. We'll round it off with a quick project status and a plan for the next video. 00:00 Intro Part III - about OCAs, AMDs, MSAs and MDAs... 00:05 Quick recap where we left off in Part II 00:15 SSA enclosure restored 03:33 OCA - IBM speak for power supply. 04:04 Faults lights 04:31 Voltages and power ratings 04:44 OCA disassembly 09:04 PCB is out 09:30 And there’s your dead bug. 10:49 Board looks good. 11:15 The Air Moving Device 12:34 Let’s see what's inside 13:21 MSA reassembled after cleaning 15:00 AMD time for reassembly (sorry for the camera creep) 15:41 AMD is done. 15:49 Project status 16:21 Thank you and outro. #retrocomputing #IBM #mainframe #S390 #restoration
