    text: I worked there from Apirl 1978 to may 81. It was orange and green. When I began working there we began producing the Mz which was tan and black. There were lots of complaints about the orange and green colors so they (Lore and Carole) decided to go with something more neutral. Some of the comments were that only women with come up with that color scheme.

    text: I have an Orange Vector Graphics 1+ that is still working and controls my Yaesu FT767-GX amateur radio transceiver. It has a 5 1/4" floppy disk drive, and a Z80 processor. I bought it in kit form and assembled it, including all the S-100 boards sometime around 1978-1979. I used a Soroc IQ120 terminal with it then but later switched to a HP 700/41 terminal.

The Vector 1 was a clone of the ALTAIR 8800 based on the common S-100 bus structure and the Intel 8080A microprocessor. It was sold under kit or assembled versions.

Vector Graphics said it offered a stronger cabinet and a well-designed power supply. To reduce selling price, front panel didn't offer any switch or control led. In its basic version, the computer could be connected to a tape recorder and a serial terminal and offered a bootstrap ROM monitor.

Additional info about the company by **Dennis Ray Wingo**:\
Vector started in November 1976 when Bob and Lore Harp, along with Carol Ely took Vector's first product, an 8 k static RAM card along with a 256 X 256 line (High Resolution Grraphic HRG) card, to computer swap meets to sell. Bob, who at that time was the director of Hughes Research Laboratories (yes THE Hughes Research Labs), designed the Vector 1 computers that they started selling in 1977. Vector grew fast as a company (although not by today's standards), and by the time that I went to work there in manufacturing in April of 1981 they had just crossed the 3 million dollar per month revenue milestone. Vector went public later that year at $13 dollar per share. Bob and Lore divorced soon after the IPO and Bob left to found Corona Data Systems, one of the very first clone IBM PC companies.

**Mike Boyd** adds:\
The unit was well built, like a prelude to the NorthStar Horizon; unfortunately the push buttons they used for the power and reset were terrible, and would fail - you had to sometimes hit them several times to turn them on.

About the terrible buttons, **Lore Harp McGovern** specifies:\
The buttons were custom dyed and a big pain in the beginning. Designing a switchless front panel was not a cost reduction issue, but a human interface issue. The 1702 PROM board made those activities transparent.\
User friendliness became an important design element at Vector Graphic. Simple is better for the average person!
