I have managed to re-produce the minestorm screen overlay which was missing from my Vectrex, with great results. See the pictures Here: 1  2  3

I've now also created a reproduction overlay for Berzerk. Here's how to do it in 3 easy stages:
1. Use a colour printer and a transparency sheet to produce the overlay copy from a scan. Photo
2. Use tippex to colur in the transparent areas that should have been white (tippex the back surface!) and then usa an A4 laminator to seal the sheet and make it the correct thickness. Photo
3. Cut out the overlay to the correct size and there you have it! Photo
