Good of you for saving that perfectly good monitor! This instance of an iconic classic might be already crushed to bits if you hadn't spotted it. As you say, it's not that rare (yet), but working ones are increasingly less and less common.
@@blackterminal I trashpicked a small TV last August. I haven't found any CRT monitor on the curb in ages, though. I guess the vast majority of those got dumped long ago. Either that or they go straight to recycling centers, which are not open to the public in my country.
@@BilisNegra the most modern crt tv I have was left on the side of the road for a week before saved it. Works well. I also have the family woodgrain console tv, plus a 14 inch and another 21 inch that currently doesn't work but I'm doing my best to repair. I have many crt monitors of various types.
Inspired me to pull out of storage the 5150/5151/5153 that my dad and I picked up, when I was in early high school. Some of it works ... some ... no (electrolytic capacitors, for the most part). The 5151 is interesting ... in that the primary of the transformer connected to power was open (schematic shows it should have a DC resistance of 16 ohms or so). I guess lightning or a power surge at my parents many years ago took it out. I think that I might adopt your approach to trying to catch e-waste here in Florida, since the parts are hard to find (and cheap your way). Thanks for the video ... Cheers.
We were still using these (and a few 5154 color monitors) with XT and AT machines in my programming classes back in 1993 when I was a junior in college. The very next semester they were replaced with shiny new 486 machines with VGA monitors after the curriculum changed to a different programming language. The college tried to sell the IBM machines for ever decreasing amounts of money. When they got down to $25, the professor had us just pitch them into the Dipsty Dumpster. Probably 30 machines with monitors and keyboards. I still kick myself when I think about it 30 years later. But at the time they were just junky old computers.
Back in the mid 90's I worked for a school district that updated all their computers to Dells. In a warehouse they had accumulated 75-80 pallets of IBMs and clones, Apples, Commodores, TRS, etc, including all the IBM monitors you mentioned! They couldn't give the stuff away!!!! Memos were sent out all year to come by the warehouse and take what you wanted! Very few takers, including me!!! 😭😭😭😭 Eventually it all disappeared. I assume they paid an e-waste company to haul the stuff away!
I had a old well used c64 monitor that blew a square shaped cap. I pulled one out of a plasma tv board along with a few other not exactly matching caps and it worked again. :)
1:30 At the e-waste facility that I own and operate, we normally charge $35 or more to take CRT monitors and tv's in. Occasionally I would see that we collected a special CRT item like this monitor and a certain level of guilt comes with knowing we likely were paid to take it. There have been plenty of times I have offered to pay for items that folks were willing to leave for free or even be charged to drop off.
Even if it’s been sitting unplugged for quite a while, CRTs and other high-voltage capacitors can retain (and sometimes recover over time) enough of a charge to give you a seriously unpleasant time if you touch the wrong spot. Discharging everything at the start of a repair is still a good idea just in case.
I got one of these given to me recently. I heard something rattling around inside. After carefully taking the cover off (and breaking the plastic about four times), I found about 20 bits of plastic inside. This is the most brittle plastic I have ever seen. The slightest force will break it. Mine must have been roasting in the sun for a long time although it's not very yellowed.
I have one of these 5151 monitors in the ibm box my dad has had in the basement on a shelf for years. We no longer have the IBM PC though to connect it to.Is there any way to use a jumper or adaptor to test to see if the monitor turns on and works without having a pc to connect it to? I have a few older pcs but none that have a 9pin video. Thanks and love the channel!
Unfortunately, the signal frequency is different. I am not sure what sending a VGA signal into an MDA monitor would do to it. I have bought little VGA signal generators in the past from eBay/AliExpress, but I haven't seen one that does MDA.
Just want to throw a question out there as Ive seen you work on this type of gear. Do you know of a glue, adhesive, bonder, or whatever its called that can be use to repair a cracked/broken monitor case? Everything I've tried (superglue, epoxy, MEK) just doesnt hold for very long especially once things are moved around.
I didn't know that EGA worked on the IBM 5150; Obsolete Geek only put a CGA card in his video of him pimping out his IBM 5150, so I thought that was as high as it could go.
Could I have someone's advice? I have a ancient apple 3 crt and the case has a big Crack after a fall in a earthquake. What is the best glue to use to repair the Crack?
caution...don't spray cleaner onto a monitor, spray on a cloth first. The spray can go where you don't want it and cause problems. Good video, sorry to be picky but that was my pet pieve when I worked on computers.
@@RetroHackShack It also refers to the court verdict in a high-profile case involving Mr. Flynn and his alleged improper relationship with two underage girls. He was acquitted of all charges after a very tumultuous trial.
What recycler is buying scrap electronics these days? The place we deal with is shredding it, running a magnet over it, and sending what's left to the landfill, as no one is buying. As someone who's pallitized plenty of CRT's, clipping the cords isn't so much a matter of making it easy to stack them. The cords end up dragging on the ground when the pallets are moved and the cords end up under the forklift tires, tearing the pallet apart.
I do. You would be surprised how much e-scrap pays. As far as the CRT monitor cables, we cut them all off. The wire has a value and the VGA connector does as well so we cut that off of the end of the wire. The wire has copper and the vga connector has gold. Both pay about $0.75/lb (todays rates) and add up real quick!
@@boardsort Last time I talked to the the E-waste guy, they couldn't get rid of it at all. I know the scrapyard my father deals with has told him to not bother bringing in cables such as telephone, ethernet, and other fine wired cables(i.e. VGA cords) with the insulation on, as the cost to dispose of the insulation far exceeds the copper value.
@@ravenbarsrepairs5594 Wow that is a surprise. I would bet a little phone work and you would easily find a local buyer for the wire. Curious where you are located. Perhaps those yards could use some updated price lists.
@@boardsort Not much choice in where to take it, as I'm in Norther NY, on the Canadian border. Trucking costs alone eat up a lot, as they're shipping it at least a few hrs north into Canada.
If you had put the correct female power plug on it, you could simply have put a standard IEC power cord into it when you needed to use it with another machine.
No, I mean the socket on the original female cord accepts a standard male IEC power cord. So if you had returned it to original condition you could still have used it with the IBM as intended or simply plugged a cord into it to use it with a machine whose power supply didn't have a pass through.
6:13 Of course you broke it, because the way you opened it was wrong. You need a very thin screwdriver to gently bend the latch that holds it all in the monitor. Then you can remove it without breaking it. And no, you won't fix it with super glue, because it will crack again the next time you insert it. Trust me.
That monitor looks stunning. I always appreciated the contrast that mono monitors provided.
For sure
Good of you for saving that perfectly good monitor! This instance of an iconic classic might be already crushed to bits if you hadn't spotted it. As you say, it's not that rare (yet), but working ones are increasingly less and less common.

Awesome. I hope you can get it working.
Same here. The primary of the transformer has an open. A replacement is orderd.
Nice find, especially for the price. It cleaned up nicely!
Yeah. I need to find one more now since I gave that one to my friend.
That IBM pc setup you have is beautiful .
Awesome video! Can't wait to work on the IBM, thank you again !!

Reinforce plastic with superglue sprinkled with baking powder. Forms new sandable plastic.

Everything I've tried (superglue, epoxy, MEK) just doesnt hold for very long especially once things are moved around.
If the case is made out of abs plastic you could use acetone and some spare abs scraps to bond the plastic back together.
I didn't know that EGA worked on the IBM 5150; Obsolete Geek only put a CGA card in his video of him pimping out his IBM 5150, so I thought that was as high as it could go.
Could I have someone's advice? I have a ancient apple 3 crt and the case has a big Crack after a fall in a earthquake. What is the best glue to use to repair the Crack?
does the IBM 5151 use ac input or dc input?
If ye wanted to, you can get an adapter that you can plug that monitor into and then that plugs into the computer :)
Good suggestion
@@RetroHackShack then I saw you sold it lol, a lucky friend you have. Wish I had a genuine monitor to go with my 5160.
Electrolytic caps can be dried out and still look fine. To really know you have to do individual tests

That wouldn't be called the 'analog board' because there is no 'logic board'; it would just be a circuit board.
If you had put the correct female power plug on it, you could simply have put a standard IEC power cord into it when you needed to use it with another machine.
Do you mean to install a female plug into the monitor chassis? Yeah. I did that with one of my other rescues.
No, I mean the socket on the original female cord accepts a standard male IEC power cord. So if you had returned it to original condition you could still have used it with the IBM as intended or simply plugged a cord into it to use it with a machine whose power supply didn't have a pass through.
