    PDP11/23 Project Completed (at least for now)

    I recently completed some long overdue upgrades to my Micro-PDP11/23, and thought I would share them here. I got this machine about 20 years ago from the building manager of a building I used to work in. She was happy to have someone get it out of her office, and I gladly took it! It had...

    New fans for my Micro PDP11/23

    The cooling fans on my Micro PDP11/23 were wearing out - the bearings in one were failing and the fan would no longer spin, and the other one was getting loud and rattling a bit so I wanted to replace them. After looking around a bit I found a 12v fan that has slightly lower CFM, but is much...

    AT&T 3b2/600 with ZuluSCSI

    I haven't been able to find any other posts about getting a ZuluSCSI to work with an AT&T 3b2/600, so I thought I'd share my experience here. My 3b2/600 has 2 70MB ESDI hard disks in it, and they are connected to the SCSI controller through an Emulex SCSI to ESDI bridge card. I figured I...

    IBM System/36 5364 PC

    My first post here :) I wanted to say a huge "Thank You!" to @NeXT for the blog post on how to recover unknown userids and passwords on the System/36. I've been working on getting mine up and running, and your blog post worked perfectly for me - I can confirm the process does work on the...
