All 3 others of my group most probably have no dice, I can count on 1 person having a D6(Like me), and the other 1 may have some dice, I don't know(He played 1st ed). The last one won't, I'm sure he as has only played BG:1. I have a D6 to.
put numbers on small pieces of poster board or notebook paper and place them into a cup. Then pull numbers from the cup, I'm sure your 1e player will like this.
And if you want to be high-tech, put a laptop in the centre of your gaming table and have a pseudo-random number generator running.
Just be aware that it's only pseudo-random numbers, so your complete D&D game will become deterministic...
I would just buy some dice. If you can't actually find a store that sells them, there are some spiffy dice included in with the DnD intro game. And of course you can always order dice on-line.
