The discussion of the Alien series of films and the props used in them is the aim, but if it's got Big Bugs and Big Guns, then they are welcome too!

After seeing SimonT's thread about getting hold of a second hand Grid laptop it occured to me that I might be able to scratch build a static replica from plasticard.
First though I've made a prototype out of cardboard before I move onto spending any money.
I plan on buying two PC keyboards to use for the parts for the keyboard and assorted connectors for the rear. I would like to confirm two things, firstly should the computer have a diskette drive on the side? Also I want to check the connectors I need on the back. From what I have found so far I need the following: 1 rocker switch, 1 IEC C14 power socket, 1 fuse holder (scratch build), 1 voltage selector switch (scratch build), 1 15 pin (3x5) D-type, 2 4-pin modular sockets, 1 24 pin GPIB. Is this the correct set of connectors?

I have to say I like your cardboard prototype! Reminds me of the stuff I built from ALIENS out of cardboard as a kid.

Sorry I have no help to provide.

The computer is 38x29x5cm in size. My plan is to create a set of instructions and templates if successful so that anyone can reproduce what I may.
