So what do you do when you get tired of your 3/60 swapping itself to death? Easy -- add memory. SIMM sockets are there, ready and waiting. Actually, not so ready. I know this because when I added memory to my 3/60, I found that the `next' SIMM socket didn't work. The problem was a *missing* pin from the underside of the socket. Nice empty reflowed hole where a pin should have been. The only way this could have passed testing is if there was none. Pretty bad when you consider that connectors and cables are the most defect prone components in an electronic assembly. Thanks Sun.

Did Sun ever guarantee that you could install SIMMs yourself and have them work? Betcha they didn't. :-) Assuming they did a proper job of hardware quality control (I will not comment on how realistic this assumption is :-)), they tested the configuration as shipped, on the assumption that whoever installed field upgrades would test those upgrades and not release them to the customer until they checked out. I don't, offhand, know of any manufacturer who tests all possible plug-in extras when shipping a box without them. Henry Spencer at U of Toronto Zoology henry@zoo.toronto.edu utzoo!henry
