Ultra 386 SX20

Intel introduced the 386SX CPU as a bridge between the generation machines built around its aging 16-bit 286 chips and the more full-featured, state-of-the-art 32-bit 386 processor. These were the days when personal computers were beige- or putty-colored metal boxes and people could easily spend $5,000 on a single computer. Programs ran on MS-DOS, which executed in about 65K bytes of memory, if my own memory serves.
