It’s time to boot the Plexus P/20 into UNIX, or at least try to! In the previous parts I managed to dump the hard drive (for archival purposes) and dump the ROMs. In Part 2 I worked on making sure the power supplies were stable and working well enough to run the machine. Now it’s time to actually try to boot this machine into UNIX and see if it works!

Part 2:
Part 3: This part
Part 4: Coming soon
