 Well yes and no.  Putting memory in the 3/60 is pretty straight forward.
Just add more memory in the slots behind the existing memory and "adjust"
the jumpers to reflect the current installed amount of memory.  Don't
forget to set the numbers in EEPROM via the ROM monitor too.

Putting memory in the 3/80 is about the same except the slots are in TWO
banks and the expansion memory does not fill the slots in a straight
forward manner like the 3/60.  The manual for the 3/80 is wrong too.
Follow the TEXT on putting in more memory and ignore the picture, its
totally wrong.

Finally, memory for a 3/60 will NOT work in a 3/80.  All SIMMS are NOT
created equal.   Also I think that if you look at the memory in your 3/60
that came from Sun you'll find that is 120ns or maybe 100ns but NOT 80ns.
You've paid a primmy price for speed you can't use if you have 80ns.

Try CLEARPOINT.  We've had real good luck with them.  They maybe a touch
higher than the other big Sun memory vendors but their product and service
seems to much better.
