In part 2 of my IBM battery disaster video series (for part 1 click https://www.youtube.com/watch?v=qn6sHMqvRMY), we try and get the machine up and running by tackling the expansion cards. The hard drive and disk drive controller card, the memory expansion card and the serial / parallel card. I'll also show you how to setup your 5170 in different ways. There will be a third (and perhaps also a fourth) part in this series, as we haven't reached our end-goal yet. #IBM #PC #AT
