Intel Mobile Pentium MMX microprocessor

120 MHz

TT80503120 is the slowest Pentium MMX processor ever produced by Intel. This processor was only manufactured in Tape Carrier Package (TCP) and used in mobile applications. The CPUs in this package type had to be soldered, and to simplify laptop part manufacturing and replacement the microprocessors were usually mounted on separate CPU boards, There were a few different types of CPU boards for laptops, and one board type was simply a socket 7-compatible PGA adapter with soldered microprocessor (pictured).
