   <media:description>This TI-810 Printer was very kindly donated by BoxcarJim and it was in such unbelievably good shape, I thought it would be a walk in the park to bring back up. But, as I’m sure most of you are keenly aware, printers always throw curve balls. We had all sorts of failures to overcome and then the nightmare of cabling. In my defense on the cabling issue, I had the wrong manual, which made life way more difficult. We got there in the end though, and bent this thing to our will!

   <media:description>I can’t fault them, they’re nearing 70 years old, and that’s a big ask from diodes that old! Still, we know for a fact that we have at least two bad diodes, and I suspect we may have dozens more. Which means, it’s time to test diodes. But when the machine has more than 3,000 diodes lurking inside of it, how do you test that many without losing your mind? Well, turns out, Bendix made a pretty awesome little tester to do just that!

Kind of… It boots, and let me tell you, it was an absolute journey to get it to that point. But, it’s still not quite right. It’s trying to execute code, it’s just executing the wrong code. Still, with multiple bad germanium diodes and even a bad photodiode holding us up, it was an absolute battle to get to this point. But man alive was it worth it!

   <media:description>Usually, I rotate through about four big projects, but lately, I’ve been falling behind with some basic housekeeping around the shop, so today, let’s do some of that housekeeping. I’ve been amassing MFM drives for about a year now, and it’s finally time to take them out, and see which ones work and which ones don’t. So, let’s bust out the Gesswein MFM Emulator and a screwdriver and make some questionable decisions!

   <media:description>I love teletypes, which might seem like a weird thing for a vintage computing dude to say, but really, teletypes are just electromechanical data terminals! The communication protocol is a little different, and of course you’d have to match speeds, but it receives serial data and transmits serial data, it just does it with motors and contacts and spinny bits. And that makes them awesome.

   <media:description>This is it, this is the first real step towards completing the project! And boy what a step, because we step right out of our comfort zone, and right into machining and manufacturing. You can see in the thumbnail that some successful machining took place, but it wasn’t without its frustrations for sure. This is a fun one y’all, so tag along as turn big pieces of aluminum into small pieces of aluminum.

   <media:description>Hi, I’m sick.
Hi, Sick, I’m Dad.
No, literally, I’ve got some kind of upper respiratory thing going on and it’s no fun. I am coming out the other side of it, however, when you’re loopy and contagious, there are certain things you shouldn’t do, like invite people over or play with heavy machinery. So, today, we’re taking a bit of a break to take a look at an adorable little data terminal BoxcarJim donated!

   <media:description>In the previous episode, we got the 11/44 up and running, and it looked like it was trying to go, but we kept running into a problem: we couldn’t halt the CPU. Which seems like a really weird thing to want to try to do, but PDP gonna PDP. At any rate, we need to get the CPU to halt so we can start trying to run stuff on it, as counterintuitive as that sounds. So, today, that’s what we’re going to tackle!

   <media:description>You guys called me out on it, and you know what, y’all were absolutely right! My understanding of straddle erase versus pre erase was definitely flawed, and I’m so glad you all spoke up about it. This particular drive came from the amazing Dave McGuire over at the Large Scale Systems Museum (https://www.mact.io/) up in Pittsburgh, and in the previous episode, we didn’t get it going. Can we get it going in this episode? Well, at 40+ minutes, I bloody hope so!

   <media:description>The one-bit vacuum tube computer is back baby! Well, kind of. The reason it’s been so long since we last took a look at it is because I’ve been doing some serious thinking about how best to build the paper tape. I experimented with a lot of ideas before finally settling on a “Keep It Simple Stupid,” approach. Fair warning, this episode is primarily to get everyone back up to speed on the project and let y’all know what direction we’re now headed in for the paper tape. The good news is, we have a gameplan, so things should start shaping up real soon!

   <media:description>The G15 wants to run, I can feel it, but there’s just a few things holding us up. The typewriter is giving us the run around, so first order of business is sorting that out. But in the process, we find all sorts of weird modifications to the typewriter, and then we run into even more troubles with the paper tape reader. But, progress is progress and we’re getting closer and closer to fully booting up!

   <media:description>It’s no secret that I’m a huge fan of spinning rust, and so I’m always going to jump on an opportunity to work on my all time favorite hard drive, the CDC Hawk. This particular drive came from the amazing Dave McGuire over at the Large Scale Systems Museum (https://www.mact.io/) up in Pittsburgh. But, this Hawk Drive is a Straddle-Erase instead of the Pre-Erase I need. What does that mean? Well, that’s what the video is for!

   <media:description>And now for something completely different. I’ve been going pretty hard at work lately, so it was time for a little time off, and what better way than to hop on a plane for the most wildly perfect country in the world. Hop on along with us as we see some historically significant computers, do some pretty righteous thrifting, and go on a road trip through the most beautiful countryside you’ll ever see.

   <media:description>The PDP-11/44 power supply has been giving us the proper run around, but I’m too stubborn and dumb to know when to quit, so we’re right back in the thick of it in this episode. Only this time, I come out of the gates swinging and emerge victorious! Sometimes, not knowing when to quit is a good thing. Once we got all the power rails up, it was still a bit of a challenge to get proper life out of it, but we got there for sure!

   <media:description>This is the big one – we push that tantalizing green button to fully bring up DC and get the machine online! Of course, things don’t quite go as planned, and we didn’t get as far as we had hoped. But, lots of exciting things happened and the machine is in a very good state to be brought up fully and executing code soon!
