Vector Graphic 3 microcomputer released by Vector Graphic, Inc., circa 1978-1980, which features a fixed keyboard housed in a combined screen terminal and CPU case. The back panel bears a manufacturing label that reads: “Model No. V3-5030, S/N V3-03725.” Includes an external Vector Graphic 5¼-inch floppy disk drive with label on the reverse marked, “Model No. DDW-5017, S/N DDW-02047,” and two Vector Graphic binders, one for “Operating System & Utilities Software” (CP/M 2), and the other for “Vector 3 Hardware Manual.” Confirmed and tested to be fully functional and in working condition; the system bears light scattered scuffs and wear. Accompanied by a Vector dust cover.
The Vector Graphic 3 was a late-1970s/early-1980s business-class microcomputer built around a Zilog Z80 CPU on an S-100 bus, packaged in an all-in-one terminal-style case with an 80×24 green-screen monitor and a full keyboard. Typical systems had around 64KB of RAM, external 5¼-inch hard-sector floppy drives, and often a small hard drive. Inside the case was a cage of S-100 cards for CPU, memory, and disk controllers, making it a ‘serious’ expandable CP/M machine rather than a home computer.
It primarily ran CP/M 2.2 but could also use other Z80 operating systems, and it was commonly sold as part of a turnkey word-processing setup called Memorite, bundled with a printer for office use. Historically, the Vector 3 represents the peak of pre-IBM-PC business micros: a professional CP/M workstation from Vector Graphic, one of the notable early microcomputer companies, co-founded and led by Lore Harp, and later overshadowed when the IBM PC and MS-DOS took over the market.
