the chip that made Intel
I would add that the 8088 had an 8-bit data bus. The standard DRAM chips at that time were 16K x 1 bits. A minimum system was 16K, with 8 chip increments. The 8086, with a 16-bit data bus, required 16 chips minimum and 16 chips for any additional bank of RAM. Soon after shipping, 64K x 1 bit DRAM chips became available, so the 64K byte system required only 8 chips, where an 8086 system required 16 chips. The minimum system for an 8086 using 64K DRAM chips was 128K bytes.
