        The 3240 is very similar. The only difference I can think of is the
presence of 4 ISA slots. I was told by a MIPS engineer that those slots
were designed specificly with Digiboard serial port boards in mind. In
case you wanted to use the thing as a terminal server. So, yes, they
would be considerably limited. 

        I haven't turned on either of them in about 2 years. the 3240 is
serving as a glorified bookend. It weighs so much I'm using it to
sandwitch a full tower case that lacks feet up against a cabinet. Rather
unfortunate since I have a whopping 40 megs of ram installed in it. Two
16-meg boards and one 8-meg. Naturally, the battery in the RTC has died
long ago as well. I hear I can order a new one from Mouser for about
$20, but, bookends don't need to know what time it is. 

        But I keep the 3240 around for sentimental reasons. I had a "borrowed"
account on it many years ago. Was my first shell account. The university
that owned it surplused it, and for $100 i figured it was worth
completing the circle.
