	No, there is space for a total of 512k using 64kx1 chips or
	2Meg using 256Kx1 chips.

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.
