This kit includes 4 modules of unknown-MB SIMMs your Sun Microsystems Ultra 1 or Ultra 2 machine. I pulled these out in working condition from my Ultra 2 when I upgraded. I can't seem to find what the actual module capacity is on these, but I suspect they are 64MB each (256MB total for 4 modules). Please don't hold me to that. If you know the specs on these machines, please let me know too. :-)

long time computer enthusiast trying to clear out old stuff. this was pulled from an old computer I upgraded but I no longer have (and hence can not test), it was in working condition the last time it was used. looking for vintage PC collector who might want this.
