The Plexus P/20: A Fantastic Journey (Supercut)

[@TheInternetHelpdeskPlays]

Even though I've watched the whole series when it came out, I'm watching this supercut because its just such an amazing story.

[@mickr777]

Hope you feel better soon

[@adriansdigitalbasement]

Thank you! I really appreciate it.

[@jakemcgregor8117]

I love watching you work through bringing old systems back to life and explaining it along the way. You really help people like me to understand the process, and learn so much along the way. Keep up the great work!

[@garymetheringham4990]

Get well soon pal, these long vids are my favourite. better than shorts!

[@pipschannel1222]

Hang in there, Adrian! Get well soon! 💪

[@evilborg]

This is probably my favourite series so far !!

[@cremvustila]

I wish you a quick and full recovery! This series on the Plexus machine was awesome! Thank you, Adrian!

[@xilendorf]

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

[@myleft9397]

Get well soon. Oh that intro! I'm at the edge of my seat for part 6!!

[@tibbydudeza]

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.

[@diegoknyte]

Such a majestic machine. Amazing work, and a splash of luck, from you and the community on getting this beast going. I's really fun watching you go thru your thought processes while fixing this stuff. It's techie but not so much that it can't be understood by the lay-person. Good times!

[@evaDrepuS]

Still one of the coolest retro computing devices I have ever seen. Awesome series Adrian. Long form content is the best.

[@Fir3Chi3f]

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

[@quakesin1982]

I'm finally ready to watch the fantastic journey! I'm excited.

[@nesyut]

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 :-)

[@marcinkowalczyk647]

hang in there lots of health and best wishes !

[@emq667]

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!

[@Downeast-and-Friends]

Get well soon, I find your videos relaxing to watch. Even if I never use it I am learning! Lol

[@Choralone422]

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. :)

[@Jerrec]

I love the Plexus. Hope there is MUCH more coming. This is much better then anything else.

[@stinkertonsden]

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.

[@DavidLightman]

I got that too, almost recovered, haven't got out of my house for the last two weeks :( get well soon!!

[@enojelly9452]

This was deeply enjoyable.

[@imqqmi]

I've watched and enjoyed the separate parts, just came in the like and comment to help the algorithm!

[@MarianoLu]

4 hours of Adrian and and the Plexus.. I’m in!

[@RonaldThompson-b3f]

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.

[@GYTCommnts]

Get well! You are awesome, Adrian! Love your work and your channels! 💪

[@JohnDee1527]

I love everything about this!

[@Colin_Ames]

Sorry to hear that you’re sick. Get well soon!

[@jonathancombe9991]

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!

[@KeiyentaiYotaiya]

Awesome. Can't wait to find out the new stuff. Get well soon Adrian.

[@Null_Experis]

Oh wow, the technical docs being on an old unmapped partition, saved by a typo is wild.

[@bikeforever2016]

Take care and time. Mend well. All the best.

[@lpseem3770]

Imagine the whole Fallout 1 storyline would be finding clock replacement for Plexus instead of waterchip. I would rather play that.

[@Dennixx]

Get well soon Adrian!

[@m7hacke]

Take whatever time you need to get better.

[@thomasschuler5351]

FOUR HOURS! ❤ without further ado, let's get right into it

[@oblitum]

LOVE THIS CHANNEL 😍😍😍😍😍😍😍😍😍😍😍😍😍😍😍

[@copperdog01-i2o]

I know what I'm gonna have playing at work today!

[@jonwilson3821]

same lol

[@AshtonCoolman]

Now get the 8-bit guy to make a Planet X3 port for it!

[@imqqmi]

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.

[@AshtonCoolman]

@@imqqmi aww shoot, you're right. It doesn't have a basic video card...

[@seritools]

Oh great, a new super mini mailcall! :^)

[@PhilippeLacoude]

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. 😀

[@BobHewittMusic]

Get well soon, Adrian!

[@aleksandardjurovic9203]

Get well soon!

[@SockyNoob]

This is such a sexy machine. What an absolute monster.

[@TPerry2828]

Get well soon, mate 👍

[@Nerd3927]

Oh well, just one more video and then I go to bed.... :-)

[@RM-pn5tq]

Fantastic video!! Maybe the old tech data on HDD was a standard image put onto all systems as part of manufacturing tests, then normally over written. (Wrote this before seeing the last 10 mins😅)Regards to Dallas chips, I learnt from a great video on removing the expoxy crap, slightly heat it up with a air gun and it flakes away revealing the ic and the old battery with no residue left behind!

[@uomoartificiale]

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!

[@ryanatkinson2978]

I'm dealing with covid right now too! It seems to be going around Portland at the moment, my roommates all have it too

[@JSparrowist]

LETS GO!!

[@testingchannel5440]

I am the guy who asked for loooooooong uncut videos during the VCF Southwest, if you remember. Get well soon

[@DJ-BeerHunter]

get well soon

[@nixter57]

Please get More Sunshine & Vitamin D !!

[@DW-indeed]

Take care of yourself AB 💪

[@candydeebe2725]

Get well soon, Sir

[@Jookia]

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.

[@FluffyTheGryphon]

This thing reminds me of the gonk droids from Star Wars

[@marcinkowalczyk647]

any updates yet on the PLEXUS ?

[@TomassAfastass]

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.

[@picklerism]

GONK!

If you are sick you can just skip a week, nobody will be mad.

[@wiwingmargahayu6831]

Wow

[@robertsmith2956]

Use the tape to transfer files.

[@paulkeenanmusic]

Gronk!

[@Jerrec]

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.

[@ryanatkinson2978]

Where did you get that ram plushie? I want it lol

[@kalayos1]

I keep hoping you will run across an old Prime mini computer Used one on the back of the day.

[@sanityormadness]

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?

[@sawomirmarnotrawny1694]

it would be fun if u can find a tape and writ on it.

[@BestSpatula]

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 KZbin time. This isn't sarcasm, and I truly appreciate it. 💙

[@timblack4123]

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?

[@chloedevereaux1801]

its debossed ( raised ) not embossed ( sunken )...

[@marcinkowalczyk647]

wonder if any Plexus content is queued up for 2025?

[@richardwaters9284]

it's not done until you can play Zork on it!

[@Chris-wt1eq]

Supercuts are kinda like cheating but know it works for KZbinrs so will keep it on repeat for the next week buddu

[@andrasszabo7386]

Does this run DOOM? Anyway, get well soon, Adrian :)

[@belstar1128]

it doesn't even run pacman maybe zork

[@SimonSays-Techtalk]

You sound out of breath. Get well soon and take care.

[@MrArpSolina]

This video is too short!

[@mw2freak74]

hey adrian, been a subscriber for a months love the videos. I wanted to drop a book i recently found that might help u on ur PLEXUS journey, might take alittle bit of tracking down but it should have some of the original source coding formula for this machine, "Source Coding Theory" Robert M. Gray (Kluwer Academic Publishers) it says in the end of preface page, "book was orginally written using the eqn,troff utilities, and was translated into LATEX in several UNIX" hope this helps

[@mw2freak74]

currently trying to track down the spooky mystery of source coding technology myself.

[@bzuidgeest]

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.

[@Otakunopodcast]

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"
