Which seems like what I am envisioning...

And brings up another thing I was thinking of.

I've had a Compaq Laptop that I got for $20 a year ago.
I *WAS* gonna try and use it, converting it over to use EMC.
That plan ended two days ago when a cat jumped up on the table in the
kitchen,
knocking it to the floor, sending bits and pieces flying everywhere.
Anyway, now I have a Pentium 233 piece of useless plastic,
as the motherboard hard drive controller seems to have taken the brunt
of the destruction.
Is there a way I can salvage any of this to use directly on the machine.
Like maybe the LCD and keyboard?
Has anyone used a laptop display remotely for their machine?
