From time to time, we get to know that our CPUs are not bug-free. The terms ‘Spectre’ and ‘Meltdown’ comes to mind. However, there are many more flaws that sneak into a final production of a microprocessor. Have you heard of the ‘FDIV’ bug in the original Pentium? This bug resulted erroneous floating point calculations. Intel fixed this flaw and offered…
Intel released Pentium II and Pentium III processors on the Single Edge Contact Cartridge – or SECC. This type of package was required because it allowed to move the level 2 cache chips from the motherboard closer the to silicone die. Intel wasn’t able to integrate the L2 cache into the CPU die yet. Later Pentium III models, also known as Coppermine, integrated 256kb of level 2 cache…

Unfortunately, I wasn’t immediately able to work on the boards due to other projects that I thought were more interesting. Little did I know that those six boards may be more interesting than I thought!

A guide to upgrade the Sound Blaster 2.0 with chips that enable the Creative Music System (C/MS).
Sound cards with ISA interface trigger that one nostalgic feeling in me and remain that one piece of technology I have fond memories of. That may be surprising since this was also the time when you had to constantly fight with resource conflicts: DMA, IRQ, and I/O ports are just a few of…
