What a wild ride!! Definitely a fascinating look into a Unix system of old before the boom of the personal computer market. Bad clock chip, bad flip-flop from a battery leak, faulty reset circuit in the power supply, and missing/hidden partition for the docs on the system design. Heck of a ride.
Hope you kick the human malware to the curb soon! I've already seen all of the Plexus P/20 videos as I've been captivated by this series, but I'm going to have to watch this supercut to go through it again. :)
Damn. Sorry to hear you’ve got COVID. I might leave this supercut until the weekend when I’m working in my own projects (currently putting together an RC2014). Looking forward to the follow-ups though. This Plexus series has been really fun to watch. I think I like it because I KNOW that there’s no other videos about this machine because the machine itself is (probably) unique. That makes this series very inspiring because you’re essentially going from first principles - with a little help from the community, of course. Very cool!
If I start at 7:40 PM I can be done around midnight, including the snack and other pauses. 😍 Great. 🤓 I already watched the series. It was awesome, BTW. 😀
Thanks Adrian - really enjoyed watching this project. When I went to university, we used an NCR Tower computer running on a Motorola 68020 that ran Unix System V serving 40 terminals for us third year students. Forgot how many minicomputers there were before Intel 386 gave you a cheap workstation grade performance and companies started making dual CPU servers and the likes of Sparc,Mips and Motorola exited the mini/ws market.
Get well soon Adrian and thanks for your wonderful videos I enjoyed learning about this interesting computer and your efforts to fix it. Looking forward to the next update. I know if you publish videos very regularly (as you do) people can start to assume the worse if you miss one or are late publishing it! So I hope you don't feel any pressure to publish something, rest up and get well!
A serial port text mode ansi version since it doesn't have a video output or grapics card lol! Maybe a planet x text adventure would be more appropriate.
At 02:40:48 you put the text on screen "I'm now in contact with that person!", meaning the engineer designing the Plexus. Could you please elaborate on that? I'm super curious about the technical details, but also (maybe even more) I do want to know about the reaction you got from that person getting contacted about a quite surely anonymous job they did some 30 years ago, with thousands of people now hanging on the edge of their seats. We really are all going through a mystery though your videos, get well soon Adrian!
Ooh, rare computers! If you're interested in other rare computers, maybe have a look at the iAPX 432 architecture. From what I understand it was sold around the Portland area so maybe you could find one of the last extant machines.

Get well soon! The one thing I'd say about a "supercut" when you're unable to do a normal video is to maybe do an older series, rather than one from the past couple of months?
3:04:54 directly above the flip-flop and resistor to the left of it there are several etching lines running parallel left to right. the top most line under the white bodge or is that painted white line? anyway the etching under it is broken several times.
btw,, you loose com port connection maybe because in devmgmt.msc on the ports the power management is on. Usually it is off on COM ports, but it is on on PCIe or PCI add in COM ports.
my youtube feed is full of extremely depressing and scary political stuff that I can't stomach. Thank you for posting this and consuming all of my UA-cam time. This isn't sarcasm, and I truly appreciate it. 💙
More like the ultra long winding cut. I always skip most of these videos (I mean the original video parts) to get to the relevant information. Proper editing would cut most videos down to maybe 20 minutes of actual information. The amount of digression is incredible.
You can, in fact, mount a partition from within a larger image file. I do it all the time; it's quite handy for grabbing data off of image backups, or just exploring them. The key is that you have to pass an "-o offset=X" parameter to the mount command, to tell it where the desired partition starts. Here's a snippet from my personal "brain dump" wiki showing how to do it. run fdisk -l whatever.img note the Units: sectors of 1 * X number. This is the sector size. now take the number from the Start column of the partition you want to mount and multiply it by the sector size (from above). This is the offset of the partition that you want to mount. Run mount -v -o offset=OFFSET -t TYPE whatever.img /mnt/whatever to mount it. Don't forget to umount it when you're done! So in the case of your test image at 37:51, the command would be "mount -v -o offset=8704 -t msdos ~/test_st255_2.img /mnt/whatever"
Hang in there, Adrian! Get well soon! 💪
Even though I've watched the whole series when it came out, I'm watching this supercut because its just such an amazing story.
Get well soon pal, these long vids are my favourite. better than shorts!
This is probably my favourite series so far !!
hang in there lots of health and best wishes !
This was definitely the best series by far on this channel. I'm glad its got a supercut.
Get well soon Adrian, it might sound selfish but Wednesdays and Saturdays are not the same without a new video from you. A well meaning UK fan.

Get well soon. Oh that intro! I'm at the edge of my seat for part 6!!
I love the Plexus. Hope there is MUCH more coming. This is much better then anything else.
Hope you kick the human malware to the curb soon! I've already seen all of the Plexus P/20 videos as I've been captivated by this series, but I'm going to have to watch this supercut to go through it again. :)
This was deeply enjoyable.
I got that too, almost recovered, haven't got out of my house for the last two weeks :( get well soon!!

What a ride! This was a fun project to follow along with.

4 hours of Adrian and and the Plexus.. I’m in!
Hope you feel better soon
Thank you! I really appreciate it.
I wish you a quick and full recovery! This series on the Plexus machine was awesome! Thank you, Adrian!
Get well soon. I love the long form videos, already watched all 5 parts, but having them all together is great while doing work in the background :-)
I love everything about this!

I've watched and enjoyed the separate parts, just came in the like and comment to help the algorithm!
Sorry to hear that you’re sick. Get well soon!
Get well soon, I find your videos relaxing to watch. Even if I never use it I am learning! Lol
I'm loving this! I tend to rewatch your videos when I need something calming to fall asleep to so this is perfect! Thank you and get well soon
Get well soon, mate 👍
Take care and time. Mend well. All the best.

I know what I'm gonna have playing at work today!
same lol
LOVE THIS CHANNEL 😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍
Oh well, just one more video and then I go to bed.... :-)
Take whatever time you need to get better.
get well soon
I am the guy who asked for loooooooong uncut videos during the VCF Southwest, if you remember.
Get well soon
Oh wow, the technical docs being on an old unmapped partition, saved by a typo is wild.
I was pretty shocked too.
Get well soon, Sir
Now get the 8-bit guy to make a Planet X3 port for it!
A serial port text mode ansi version since it doesn't have a video output or grapics card lol!
Maybe a planet x text adventure would be more appropriate.
@@imqqmi aww shoot, you're right. It doesn't have a basic video card...
FOUR HOURS! ❤
without further ado, let's get right into it
Take care of yourself AB 💪
Get well! You are awesome, Adrian! Love your work and your channels! 💪
Awesome. Can't wait to find out the new stuff. Get well soon Adrian.
LETS GO!!
Oh great, a new super mini mailcall! :^)
Adrian's Next Series: The Return of the Freakin Plexus
I'm dealing with covid right now too! It seems to be going around Portland at the moment, my roommates all have it too
At 02:40:48 you put the text on screen "I'm now in contact with that person!", meaning the engineer designing the Plexus. Could you please elaborate on that?

If you are sick you can just skip a week, nobody will be mad.
Ooh, rare computers! If you're interested in other rare computers, maybe have a look at the iAPX 432 architecture. From what I understand it was sold around the Portland area so maybe you could find one of the last extant machines.

GONK!
Love the longer format 👍 also getting over covid 👎
Please get More Sunshine & Vitamin D !!

Wow
Use the tape to transfer files.
Get well soon!

it would be fun if u can find a tape and writ on it.
Get well soon Adrian. Now you have cut your teeth on a Linux machine, any chance you could do a series on a VMEBus system?
I keep hoping you will run across an old Prime mini computer
Used one on the back of the day.
btw,, you loose com port connection maybe because in devmgmt.msc on the ports the power management is on. Usually it is off on COM ports, but it is on on PCIe or PCI add in COM ports.
Where did you get that ram plushie? I want it lol
my youtube feed is full of extremely depressing and scary political stuff that I can't stomach. Thank you for posting this and consuming all of my UA-cam time. This isn't sarcasm, and I truly appreciate it. 💙
it's not done until you can play Zork on it!
its debossed ( raised ) not embossed ( sunken )...
Does this run DOOM?
Anyway, get well soon, Adrian :)
it doesn't even run pacman maybe zork
Every UA-camr: "Let's get right into it." But instead of getting right into it, they play a title video or go to break. 🤦♂
This video is too short!
Supercuts are kinda like cheating but know it works for UA-camrs so will keep it on repeat for the next week buddu
You sound out of breath. Get well soon and take care.
Gonk
