Minicomputer Part 23: The CDC Floppy Drive Finally Works!
Boom shaka laka! It works baby! It was a ridiculous journey, and it wasn’t a clean win, but a win’s a win. But first, let’s answer a couple questions, notably, why am I spending so much time on this floppy in the first place. And then, let’s dive into the microcode and see what it took to get that updated, and finally, let’s play around with the working floppy and see what kind of neat stuff we can do with it.

BOOTI
booting-ms-dos,-cp-m-and-rsts-e-on-a-dec
I have a problem. I’m all out of space in the room for CRTs, but I don’t have a single machine in the room that can boot DOS or CP/M. Almost every CRT in the room is dedicated to either a unique system or lives life as a data terminal. So, it’s time to start consolidating. And in this, DEC has got my back. The Rainbow 100 is an epic little triple-use machine that can boot MS-DOS and CP/M as well as work as a VT-100 terminal. This thing is really, really cool!
*: I fully realize that in the title I say, “Booting MS-DOS, CP/M and RSTS/E,” but the Rainbow 100 is incapable of booting RSTS. In this case RSTS is being booted by the PDP-11/83 and the Rainbow is being used as a VT-100 terminal. But that was all a bit too long to write in the title. However, if you're still upset about the title, write "I read the description, and I'm still pissed!" and I'll get a good chuckle and actually read your comment.

I LOV
i-love-this-dec-la50-dot-matrix-printer!
Honestly, I was planning on skipping a video this week. It’s been an emotional roller coaster of trips to the vet and struggling to keep animals alive. I’ve been an absolute wreck, and apparently, I was looking so haggard, Mrs. Usagi told me to go outside and do something to reset my brain. So, this week is a bit of a shorter video, but it got the job done and injected a little joy back into my week!

VCF East was an absolute blast, but it had one final parting gift to give me – an upper respiratory virus of some kind. Usually, I recover from these kinds of things in a day or two, but this one was particularly brutal and put me down hard for eight days! I’m finally starting to literally get my feet under me again, so unfortunately, there won’t be a traditional video this week. But, I didn’t want to leave y’all hanging completely, so hang around for a short little story from VCF that I particularly enjoyed!

THE C
the-centurion-bites-back!
First things first, Open House at System Source Museum!
Date: October 23, 2023
Location: System Source Museum, 338 Clubhouse Rd. Hunt Valley, MD 21031
Link: https://museum.syssrc.com/
We have two goals in today’s episode, the first of which is to prep the Butler Tech system for the drive back up to Cincinnati, and get a turn-key setup ready for them. I’m not taking any chances this time, I want that machine up and running 100% next time! Then, we attempt to install the Finch and Floppy drive into our main Centurion system, but the Centurion wasn’t having it. It whipped my butt six ways to Sunday, and we didn’t quite get there. But, we aren’t ones to give up, we’ll get there for sure next time!

LET

In this episode, we break out the breadboard again and build some fundamental logic gates. Most notably, we build a NAND and AND gate, which requires some pretty inventive thinking and interesting use of diodes. With these four gates, we can now build some pretty awesome stuff!

A LOO
a-look-at-our-magnavox-concert-grand
Way back in 1962 my grandfather wanted to buy a new stereo, but grandpa didn’t do half measures, so he did his due diligence and made sure he bought the very best that was on offer. And that was this very same Magnavox Concert Grand Console Stereo. Not only is it a gorgeous piece of furniture, but it’s also undoubtedly the very best sounding stereo I’ve ever heard in my life!
