I checked and tested the 755c cover, it's in fact 3 degree (tan3' is about 1/19), which is exactly what I have used. So it's easy to create one by adding two notches (holes of trapezoidal platform). https://www.tinkercad.com/things/57cfz0iHiEO-755c-pcmcia-cover?sharecode=70xMeXU0tx6Juoc0F_QnyqCBhPEE...

The side profile of the ThinkPad 75x/76x is not perfectly vertical; it has a tapered design (wider at the top and narrower at the bottom). To achieve a flush fit, you may need to set the angle between the faceplate and the latching rails to 85 degrees (a 5-degree offset from perpendicular) https://i...

OK, forget about all the dramas, if you had an N45 sl to be fixed, here is some useful info 1) AC adapter/Connector https://www.tinkercad.com/things/lhphT3ZkKBi-ibm-psnote-n45-sl-power-adapter?sharecode=mJfk6qTt11PSEx-RDxsFC6gFrrqFcUXwHGK-5f2A4Wk You need 2 pieces of 3d printable parts, the PD trigg...

I recently finished a restoration of an IBM PS/Note N45 sl, and the process was so surreal that I felt I had to document it. It started with a listing on eBay. Honestly, I hesitated. My "To-Repair" pile is already tall enough to be a structural hazard, and the new Tuff Shed I hauled home from Home D...

just some quick updates: I got another ThinkPad 300 from eBay and surprisingly it works. The seller has no AC adapter, which is common, so I think I may have a universal solution from all such kind of cases. But before that, I need to rebuild the cmos battery. While the F6 gumstick battery is hard t...

Got a GRiD 2270 from eBay in rough condition and spent weeks to fix it... https://i.postimg.cc/CBdFcsdt/rough.jpg 1. Power Supply (AC-DC Adapter) Easy, let's 3d print one. There is a 10k resistor between the positive pin and center pin. Input could be 8.5v to 12.5v, so a usb-c pd trigger with 12v wo...

correct....https://www.youtube.com/watch?v=7aJ4dDyyf20 FYI

before slice and send it to the printer, adjust the angle to 40~50 degrees in the prepare phase. for the model, it allows you to adjust it from 3 different directions, lean it and leave the longer side on the printing plane and general upside down to minimize the support. given a strong enough print...

don't print that flat, hinge part would be easily broken from joint of different layers. try align it diagonally, even for the proof of concept, like 40-50 degrees depending on the supporting.

I have all my verified model (.stl) in a google drive folder

If we all use tinkercad, we may also share the links for remix.

You may check the fuse or 0/000 resistor near the IDE first, if everything looks good, check the 5v IDE power rail by 41(5v logic)/42(5v motor)/44(type ATA) pin. Blown fuse or 0hm resistor could be simple. If you cannot get the 5v, trace back and check if there is any mosfet malfunctioned, or if it ...

SelectaDock III supports PCI version Voodoo 5 5500 which is rare, I'm afraid yours is AGP version.
You can take a look at your card and check if there is an "L" shape without gold finger, if so, it's a common AGP version.

You have the best 3d printer which supports cf-nylon/cf-petg, so I assume the ultimate solution is to rebuild the whole case. However, that's definitely pricey. I have a non-working 700 (no c) in bad shape, maybe I can start with that after I wrap up current working of grid 2270. BTW, we need a dedi...

I tried, in short, for the right side (next to the ps/2 mouse port), there is no room for enhancement. For the left side (next to the fax/modem port), you may do something but it still does not help a lot. My 2c is to sand it and then apply 3-4 layers of fiberglass mesh with glue. Plus, the hinge st...

750p and 360P/PE have the same stylus, other than that, stylus from NCR3130 also works.
I do have some spare 750/360 stylus but seems not easy to ship to SA

Restoration Update: 5 ThinkPads Fixed + PS/Note 182 I’ve just finished repairing five of my laptops, plus an additional PS/Note 182. I figured I should share some tips and experiences gained during the process for anyone else working on these vintage machines. 1. Repairing FPC Cables The Flexible P...

More about the battery... If you don't have an original battery on hand, you can easily fabricate a functional replacement using 3D printing and basic electronics. Follow the steps below to build your own. 1. The Foundation: 3D Printing First, print the battery housing. This model serves as the stru...

Ok, so I've attempted to rebuild my lid and for this attempt I'm using Araldite. As you can see I've tried to get the bases back into original positions. I think what I've learned in this test run is to get some kind of malliable putty to 'box in' where the adhesive is going to sit, to contain it t...

Happy new year! Yea, I can see all the pictures now. Hmm, the standoffs seem easily broken, but it's also easy to fix with some plastic welder, i.e. J-B Weld (plastic bonder high strength structural adhesive 15 min black, or Professional Size Steel Reinforced Epoxy Dark Grey - Hardener and Steel pac...

Your image links seem broken? I was using SolidWorks before, but I realize that designers might not have such powerful tools and they might use some really primitive ways to build the model back to 30 years ago. So I decided to rebuild everything in TinkerCAD using only basic shapes. It’s been an it...

I have had 4 versions of the "Full 3D-Printed Chassis Support Component: Reinforcing or replacing the entire mounting bracket." from PCBway - 2 sets in nylon and 2 sets with an ABS mix to compare. Before I dismantle a 425/350, I'm slightly confused how to apply these L/R pieces - is it re-using the...

I just finished rebuilding a battery pack for the IBM ThinkPad 350 using salvaged contacts and a custom 3D printed frame. There are two ways to go about this depending on your original battery type, but here is the method I used to get a working, rechargeable solution. 1. Identify and Salvage the Co...

It's ski season! Will get back and continue working on ThinkPad 350 in my spare time. :lol: BTW: seems many Dauphin DTR-1 units are missing their original stylus, I tested several digitizer pens and I found that the active pen from the Fujitsu Stylistic 1000 works perfectly. This means you can also ...

I didn't find any modern solution for the old, 1.3', HP KittyHawk HDD so I mod one myself.

IBM Type 2141 PS/note 182 and ThinkPad 350 have very similar design and many of their parts are swappable, so I copied the previous 182 hinge cap and remade it in TinkerCAD. hxxps://www.tinkercad.com/things/if1Z2T3oAr1-350-hinge-cap?sharecode=HY2kvzRQ4C2qC5z6etC47UU7DVHcJ_01wOhWjXU24jU https://i.pos...

Yea, cuz I found it's the easiest way. I guess it can be opened and closed for thousands of times before it's worn. Or, you can easily 3d print another clip when it stops working. Another work around I tried is to apply one more piece of metal sheet (yes, from Diet Coke can) inside the clip, but I d...

I have lot of failed attempts in 3d printing some support, i.e. for the missing part, better to 3d print a rough piece based on good one and then apply the epoxy or glues, but I switch to an easier solution with epoxy supported by blutack or plate and tapes. Watch out for the display shell breaking....

I just use the normal PLA filament for such kind of 3d printing. I always want to have a relatively cheap and sustainable solution, so I didn't try pa-cf and some other materials. 700/720 are almost the same, I have fixed 3 of them, but due to its design, it's hard to have some reinforcement based o...

[warning: text generated by GenAI :lol: ] My collection of five ThinkPad 350-series laptops (including the PS/Note 425 and 350c) is facing a common, critical issue: the poorly designed and prone-to-failure hinges.
