[net.unix] AT&T 3b series question

bobg@paladin.UUCP (Bob Goldberg) (07/15/86)

Does anyone know what the consequences of inserting
a 14 Mhz crystal in a 3b2/400  (which is the same cpu in the 3b15)
instead of the 10 Mhz crystal presently distributed?

to me this seems to be the only major difference between the 3b2/400
and the 3b15 - is this a GOOD cheap way to make a 3b15??


does anyone know if it's possible to put more than 4 M of RAM on the 3b2/400??

or  a 60M tape drive instead of the 23M currently installed???

The WE32100 chips come at different clock speeds (usually written on the top)
if you put a 14MHz rock in a 10Mhz system it may not work. Also the rest of
the system (ie memory etc) may also be too slow  ....  in short it is probably 
not a good idea although it might work if you have good spec parts. Look for
side effects (like your time of day running fast ....)
