In this > case, I'm refering to poor Q/A at the factory (bad cache ram, etc), poor Yes, Anyone who thinks PCs are OK should buy an electronics friend a beer, & ask for a comparison of typical industrial electronics with typical PC electronics. PC `quality' meets a market that is cut-throat, low budget, & uneducated. Systems engineering standards are not applied, result:- - Low quality tinned sockets, that allow cache ICs to work loose, (not often one sees turned gold plated sockets on PC boards). - Keyboard sockets straight on main board, allowing physical stress from plugging & knocking. - Non gold plated bus connectors & dip jumper headers, & ram sockets. - Pcb bus edge connectors instead of VME/DIP gold plated steel pin connectors. - Insufficiently physically supported long LocalBus cards, - Simplistic power ground = safety ground = emmission screen ground. - Undercooled badly machined boxes. etc PCs are very cheap, but with the `shake it & die' nature of PC hardware, I reccomended a putative customer an internal server box, an external firewall box, + 3rd cold standby box, as 3 PCs (inc. software) are still cheaper than 2 Sun/HP type boxes).
