| Description |
English: Sun Microsystems introduced its Sun Sparcstation 330 with the SPARC architecture in 1989. SPARC was one of the first commercial materializations of a reduced instructions set architecture coming from the RISC project, led by Prof. David Patterson at the UC Berkeley, as MIPS was being led by Prof. John L. Henessy at the Standford University. It was powered by a Cypress CY7C601 processor at 25 MHz along with a Texas Instruments 8847 FPU, and boasted a 72 MB RAM. My Department (Computing and Systems Engineering, DIIS is its current name) bought one of these machines in 1990, which currently enjoys a well-deserved retirement in our Computer Museum, with its motherboard displayed inside a showcase. I pass next to it a dozen times a day, and recently realized that those six crossed wires with a yellow dot -likely a decoupling capacitor, thx [1]- can't be any other thing but a late fix. Someone didn't sleep /eat /... for quite a few days or weeks, who knows, until fixing a (million dollars?) post-production bug. I find this fix really beautiful, as it completely breaks up the dullness of the circuitry.
The two outstanding big chips are the first-level cache memory controller (left), and the (off-chip) L1 cache itself (above). |
