I am interested in speeding up my PC -AT. I read the letters concerning the speed up withh interest. Lately, I have noticed a number of advertisements in PC Week magazine offering crystals of about 16MHz but for ridiculous prices like $50!! I hope some one in the netland can point me to a cheap source for a 18 MHz crystal. Furthermore, how does one specify the packaging of the crystal so that it will plop right down in my AT? Thanks Rajiv

I got my 18.4 mhz xtal from DigiKey for $2.25. It's pretty easy to order--they have life-size templates for the two sizes of xtal they sell, and the HC-18 casing is exactly the size of the AT xtal. These don't have the "fat leads" of the IBM, requiring folding over of the leads to make them thick enough to seat snugly in the socket. Some have said that this is prone to failures, but mine worked first time and I haven't had a problem. They also have 15, 16, 18, 20 and 22 mhz xtals for the more (and less) fearless. For the price, it's hard not to give it a try. They can be reached by 1-800-344-4539. MC and VISA. I don't have much experience ordering from them, but I had no problem with this order; they were fast and efficient. -- /Steve Dyer {decvax,linus,ima,ihnp4}!bbncca!sdyer sdyer@bbnccv.ARPA
