Exxon Computer Division, a branch of the Exxon Oil Company, sold this computer in the U.S.A and Europe.
This computer was built in 1982. The system is composed of CPU box, monitor, dual disk drives and a keyboard. It was delivered withe software on 5.2 disks, manuals, training materials.
This office computer was primarily a word processor with calenders, ticklers and file sharing capabilities. It ran on the Z-80 chipset with a 64 KB architecture running a CPM like OS. In some regards it is a monument to the arrogance of Senior Exxon management who felt that they were so good at managing an oil company, that surely they could manage a successful computer company.
Exxon owned Zilog, the creators of the Z80, which they purchased in 1980. The Z80 based Exxon 510 was the first system to grow out of that purchase. It has been argued by some the if Exxon had not purchased Zilog, that Zilog left alone would have rivaled Intel today. Exxon Office Systems was based on the purchase of Vydec and Zilog with the machines being developed by Compucorp and the printers being built by Qume.
Unfortunately, Exxon really mismanaged the companies and they sold off the business in 1985.
The 510 version was the basic 64 KB system.
The 520 version offered 128 KB of RAM expandable up to 256 KB.
The 530 version featured a 5 MB or 10 MB HDD.
