Compaq Contura (486 laptop)

I got this laptop for very cheap. Its a Compaq Contura 410 with monochrome screen.
The system has a 50 mhz 486 DX processor. Unlike most conturas, this is quite intact and not crushed.
It has 4+8mb RAM, and a dying 300MB hard disk. The keyboard is a standard german keyboard.
The previous owner used Windows 95 on it, but i will remote it to install FreeDOS instead.
The hard disk refused to initialize, because the head was stuck to the bumper.
I take apart the drive and gave it a light touch, now it usually initializes after a few seconds of struggling.
It has a working floppy drive.
