- What a potato…Netflix showed last night that while its content delivery networks (CDNs) continue to work well delivering static content, I believe their edge infrastructure in regional internet exchange points (IXPs) were completely unprepared for a live presentation that millions of people were watching. Netflix can start by adding more infrastructure in the 511 Building in downtown… Read more: What a potato…
- A look into the future of AI generated media and deepfakesThis seems like a good time to remind everybody about the Electronics Technician Association (International)’s Audio/Video Forensics Analyst certification program that we worked hard on several years ago. Since 5 years ago, AI has become much bigger, and “deepfakes” are an even bigger issue now. Check out the sample video I shared below for a… Read more: A look into the future of AI generated media and deepfakes
- Bethany accidentally scrams the Prairie Island Nuclear Power Plant reactorOf course, she didn’t really. This was during a May 2017 open house at Prairie Island Nuclear Power Plant in Red Wing, Minnesota, and this was a control room simulator they use to train their staff. Don’t worry, there was really never a risk of meltdown!
- New mechanical SCSI hard drive replaced in an Apple Mac SE FDHDI replaced an old Quantum SCSI hard disk drive in an Apple Mac SE FDHD this afternoon. A project long overdue! I needed to use the third-party Lido hard drive management and partition utility to get the Apple to recognize a non-Apple hard disk drive. Just as proprietary and “closed ecosystem” back then as they… Read more: New mechanical SCSI hard drive replaced in an Apple Mac SE FDHD
- Minnesota Radioddity GD-88 Codeplugs for DMRThe Radioddity GD-88 is a neat, inexpensive new dual VFO analog/digital handheld transceiver. Since no codeplugs are publicly available for this transceiver that I have found, I made one based on the Anytone Codeplugs by Eric Ganske, W0EDG. Check out the instructions and codeplugs at the link below: Radioddity GD-88 Minnesota Codeplugs

- A 5 1/4″ floppy drive connected with USB?Yup…that’s a 5 1/4″ Floppy Disk Drive, connected via USB to my computer. This board called a Greaseweazle reads the raw flux transitions from a floppy disk and recreates them as disk drive image files for modern computers. I just found disks full of music, sound files, and BASIC source code that I haven’t heard… Read more: A 5 1/4″ floppy drive connected with USB?

- Homemade Solar TrackerIt was a bright, sunny day, so why not build a homemade solar tracker? Solar trackers help solar panels always point at the sun as the sun moves from east to west across the sky. They slightly improve efficiency of panels connected to them. We took an old “C-band” satellite rotator and controller, and soldered… Read more: Homemade Solar Tracker
- 1992 SouthLAN/MNWADA Joint Packet Radio Node Install at FaribaultDuring much of 1991, the SouthLAN and MNWADA Packet Radio Clubs in Southern Minnesota planned and designed 3 high-speed packet radio nodes to be installed at Apple Valley, Faribault, and Dodge Center. The Faribault site, MNFBL:N0QVC-1, would have a 1200 baud user frequency on 145.01 MHz, a 9600 baud backbone towards Dodge Center on 430.95… Read more: 1992 SouthLAN/MNWADA Joint Packet Radio Node Install at Faribault

- Copying Number Munchers from PC Compatible through null MODEM cable to Apple //gsHaving been an Apple ][ enthusiast for 30 years, I often wondered if there was an easy way to download Apple disk images off the Internet and somehow transfer them over to an Apple to use. It so happens a program called ADTPro is available to accomplish this task with an easy-to-build null MODEM cable.
- Changes in Technology Over TimeBack in January, I was asked some questions by Amber Hallet from the Faribault High School Journalism class in regards to technology. Here’s the insight I had. What are some things that have changed over time with technology? Technology rapidly changed from the 1960s forward. The Apollo Space Program in the 60s showed the average… Read more: Changes in Technology Over Time

My Old Computers:
Having a father that was so interested in electronics and computers when I was really young had its advantages. I’ve had the opportunity to work with many systems that people aren’t even aware of today. My father is the sole reason that I learned so much about computers, and had the ability to use such a diverse group of computers.
This was my very first computer, a Commodore PET 2001 Series. It looked exactly like this, complete with the internal cassette tape drive and the little chicklet keyboard. Back in 1982, when I was four years old, I remember typing in BASIC programs of my own and saving them on cassette tapes. I also jumped over on my dad’s Apple ][ and used to PR#1 and LIST other BASIC programs to paper, and tried typing them in the PET (Little did I know the two BASIC’s weren’t exactly compatible). My father also had games on cassette tapes in little manila envelopes that he took out and let me play.
Which leads me to my father’s Apple ][. This is still one of my very favorite computer platforms. The simplicity of the platform is still unmatched even today. You inserted a disk in the drive and you flipped the power switch on. Bingo. Your program or game was up and running. Thanks to several pirate groups around the nation, users with Apple ][ computers had the most applications and the most games available on any other platform. I think my father still has this system in storage today.
Ah yes. The great-great grandfather of all computers today. An original IBM PC. Actually, I used a PC/XT most of the time. It had an Intel 8088 CPU that ran at a blazing 4.77 MHz (compared to several thousand today). This was before compatibles, and this was IBM’s answer to the Apple ][, which was still the major player. In my opinion, games available for this computer still didn’t match the quality of Apple ][ games, and there certainly wasn’t as many of them. Nonetheless, my knowledge gained on this computer right here I still use at work today. Remember DOS? Amazingly enough, Microsoft has kept excellent compatibility between systems over the years. I would say that almost ALL software developed for this computer here in the early 80s will still run on Windows XP today. You won’t get that with a Mac.
The remainder of these systems I have used myself, but don’t mean as much to me as the ones above.
Apple ][c (Portable version of the Apple II)
I think about everyone had a Commodore 64?
Macintosh 512k. Mine had a second external 3 1/2″ floppy drive as well. What blew me away about the Macintosh is that the sound quality was so much better than anything else I ever heard. This is still a system worthy of merit, unlike the bloated Macs running anything more than System 7.1.
A Wozniak Signature Edition Apple ][gs. I still have this today.
And to start my “strange and unusual computers I’ve worked with list”, here’s a Commodore 128. You could choose to make it run as a Commodore 64 to play your old software there, or as the full-featured 128. The GUI available on this system was similar to that found in the Commodore AMIGA and the Apple ][gs Finder at the time.
Here’s a Kaypro “Luggable” Personal Computer (before there were laptops). It ran MS-DOS 2. About the only thing cool about the system was its size at the time, and that the keyboard folded up and latched so you had a big metal “box” you could lug with you if you needed a computer on the go.
Here’s my introduction to the world of CP/M. It’s a Morrow Micro-Decision 2. Ours looked identical to this one here, except it had a ADMS-1C terminal on top of it for output. CP/M was a predecessor to DOS, and the commands were fairly similar. I remember working with a program called “NewWord”, that looked almost exactly the same as Wordstar.
Here’s a cool little laptop complete with a 4×20 character LCD screen, internal micro-cassette drive (that could be removed to fit other accessories), and a thermal-transfer printer that used paper that you might get if you buy something at your local grocery store. It’s an Epson HX-20.
Believe it or not, this one is still with us today. It’s an Epson PX-8, and this little laptop, with a much wider screen than the HX-20 above, ran a full CP/M operating system. This one also had an internal micro cassette drive. Back in 1996, I used to have this computer under the seat of my 1978 Plymouth Volare to check my Packet E-Mail on the road.
These final two are really scary. Here’s an IBM System 36 mainframe. I remember working on this at South-Central Technical College. In addition to this big tower, it had a huge external hard drive attached to it, 100MB I believe.
Here is a WANG Mainframe. It was huge. Very huge. And this was just one part of it. We had this out in our garage, and I think my mom probably wanted to kill my father for it. There was a WANG Terminal on top of this unit, and next to THIS unit was an external hard drive subsystem, with a set of platters probably 16″ in diameter, and there was probably a stack of 6 of them each. We also probably used enough electricity to light Manhattan in the process.
Those were my toys growing up.
Brian,
Would you like a Old RadioShack Model 1 with the expansion interface. I can’t remember how much ram it has. It was 4k before I added the expansion interface. I have it in storage. Going thru the storage shed this fall and going to get rid of a bunch of stuff. I just know that you would do something cool with it. Let me know your thoughts.
