Hey,
Recently I acquired a Tulip LT 286 laptop with an Intel 80C286 @ 12,5 MHz. It features a Conner CP3024 20 Mbyte Hard Disk and a 1.44 MB floppy drive. It was built around 1990.
It didn't come with a power supply, so I didn't get a chance to test it. In the hopes to get it up and running again I started with a teardown to see the internal state of the device. Here are some of the pictures:
The disassembled case with the screen.
The inside of the laptop. On the top right, the power supply/circuit. It has a 16.5v DC input. In the middle you can see the 20 Mbyte Connor hard disk and the floppy drive.
Hard disk and floppy drive removed.
Power supply/circuit removed.

The other side.
A label indicating the manufacture date.
Removed part of the power supply board. Shows a bit of smoke/burn on the plastic.
The back of the same print.
The other half of the power supply/circuit.

And the back of the keyboard.
I think it looks quite ok, but I do doubt if the power supply will work. Specially the burn traces around the ceramic resistors and the fact that one of them seems 'broken'.
I know recapping is the default task to start with, but if you have any advice to test the power supply/circuit, please share 😀
