RE: FW: Help! Asteroids! Please!!!!!!!

Okay - I will try that today (5:15am here and still at work - Y2K and the
world survived).

I have noticed when programming 2716's (and some other Eproms) that some
program really quickly and some really slowly.

Is this due to the design of particular eproms, or because there is a
problem with the eprom???

Happy New Year to you guys too!

(I just picked up a truck load of money for doing very little - I feel like
I'm back in the 80's)
