Review IMSAI Rare Vintage Shell Case Only Local Pick Up Read

The IMSAI VDP-80 Up is a versatile and powerful microcomputer system that was initially introduced by IMSAI Computer Systems, Inc. in 1977. This 8-bit microcomputer system was based on the Intel 8008 processor and was an upgrade from the earlier IMSAI 800 model.

The VDP-80 Up featured a 0.5-micron Intel 8080 CPU running at a clock speed of 1.0 MHz, which was a significant improvement over the 8008. It came with 8K bytes of ROM, 16K bytes of RAM, and an expandable memory capacity of up to 64K bytes using the IMSAI Extended Memory Unit (EMU). The system could be operated in both 8-bit and 16-bit modes, providing increased flexibility and performance.

The VDP-80 Up had a built-in video display processor (VDP), which was a significant advantage for its time. This VDP allowed the system to display text and graphics on a television set or an oscilloscope, making it an excellent platform for developing games and other graphical applications. The VDP supported various graphics modes, including text-only, 16x16 character graphics, and 16x16 pixel graphics.

The IMSAI VDP-80 Up had a wide range of input/output (I/O) options, including two serial ports, one parallel port, and one cassette tape interface. It also had a built-in BASIC interpreter, which was a popular choice for microcomputer users at the time due to its ease of use and versatility. The BASIC interpreter allowed users to write and run simple programs directly on the system.

The system's expansion capabilities were extensive, with various interface cards and peripherals available from IMSAI and third-party vendors. These included the IMSAI Color Graphics Terminal (CGT-1), which provided color graphics capabilities, and the IMSAI 8-inch floppy disk drive, which offered mass storage capabilities.

The IMSAI VDP-80 Up was an influential microcomputer system that paved the way for more advanced systems in the years to come. Its powerful processor, versatile I/O options, and built-in graphics capabilities made it a popular choice for hobbyists, educators, and businesses alike. Today, it remains an intriguing piece of computing history and a valuable collectible for vintage computer enthusiasts.

The IMSAI VDP-80 is an early microcomputer system introduced by IMSAI Computer, Inc. in 1976.
