Two Type II PCMCIA cards OR One Type III PCMCIA card
A circuit board that plugs into a Slot 1 and has a socket on it is commonly referred to as a "Slot 1 adapter" or "Slot 1 motherboard adapter." This type of adapter allows for the installation of processors or other components that are not natively compatible with the Slot 1 interface, providing flexibility in upgrading or modifying the system. These adapters were particularly used during the era of Intel's Pentium II and III processors.
Slot 1 motherboards were primarily designed for the Pentium II and early Pentium III processors. A Pentium Pro could be used with a special converter known as a "slotket." Later Pentium III processors could be retrofitted to work on Slot 1 boards with a similar slotket.
