Well, early 7300s had 512k then there was another option to have 1 Meg on the mother board, finally AT&T anounced the 3b1(7300++) with 2Meg on the motherboard and the hood scoop for a full height drive. As far as I know only the 3B1s only have one fan. One last note is there are several groups under unix-pc.(general,uucp,sources) You might see if these are carried by your news host. -- __ _ __ / ) // / ) / / / __. __ __ __ , // /--< __. /_ _ __ Darryl Baker /__/_(_/|_/ (_/ (_/ (_/_
