This slip-up was narrowly prevented on the recommendation of 1 of the initial progress engineers.

Capabilities of the non-public pcs components can often be extended because of the addition of enlargement playing cards linked by way of an growth bus. Regular peripheral buses typically used for including expansion cards in particular personal computers incorporate PCI, PCI Specific (PCIe), and AGP (a superior-pace PCI bus focused on graphics adapters, located in older pcs).
