The Amstrad PC1640 was based around an 8 MHz Intel 8086 processor and was a very successful entry level PC bought by many small and medium sized businesses. Not only was a success in the business arena but due to the price and Amstrad's marketing it was also largely responsible for introducing the PC into the home environment.
It had 640Kb of RAM and was available with a 20Mb Hard Disk.
Our Amstrad 1640 does include the 20Mb Hard Disk, GEM operating system and original DOS disks.
