==== SnapIn 386 ====
In May 1991, Intel introduced an upgrade for [[IBM PS/2 Model 50]] and [[IBM PS/2 Model 60|60]] systems which contain 80286 microprocessors, converting them to full blown 32-bit systems. The SnapIn 386 module is a daughtercard with 20-MHz 386SX and 16-Kbyte direct-mapped cache SRAM memory. It directly plugs into the existing 286 socket with no cables, jumpers or switches. In the winter of 1992, an additional to this module now supported to [[IBM PS/2 Model 50 Z]], [[IBM PS/2 Model 30 286|30 286]] and [[IBM PS/2 Model 25 286|25 286]] systems. Both modules were available for USD $495.<ref>Intel Corporation, "New Product Focus: Systems: SnapIn 386 Module Upgrades PS/2 PCs", Microcomputer Solutions, September/October 1991, page 12</ref><ref>Intel Corporation, "New Product Focus: Systems: More User Can Snap In An Intel386 CPU", Microcomputer Solutions, January/February 1992, page 10</ref>
