Vector Graphic was an early microcomputer company founded in 1976, the same year as Apple Computer, during the pre-IBM PC era, along with the NorthStar Horizon, IMSAI, and MITS Altair. The first product was a memory card for the S-100 bus. A full microcomputer using the Z80 microprocessor, the Vector 1, was introduced in 1977. There were several Vector Graphic models produced. The Vector 1+ had a floppy disk drive. The Vector Graphic 3 had a fixed keyboard housed anchoring a combined screen terminal and CPU case. The Vector Graphic 4 was a transitional 8-bit and 16-bit hybrid model.
