              Model of the VAX-11/780
              CERN-OBJ-IT-025 · Item · 1977
              Part of Heritage Collection Test

              It was the first member of the VAX family of computers, the first commercially available 32-bit computer and the first MIPS (one million instructions per second). It is a family of abandoned mini-computers developed and manufactured by Digital Equipment Corporation (DEC). The name "VAX" comes from an acronym for "Virtual address eXtension" as the successor to the PDP-11. The computer and its operating system (VMS) were designed from scratch. The result was a truly reliable, powerful and user-friendly system. In addition its affordable price has enabled many institutions and universities to acquire it.

              Part of Heritage Collection

              It was one of the first portable macs released. The Portable had many new advances in mobile computing : The display was crispy clear, and looked beautiful when used in daylight ; The Portable came with a Lead-acid gel/cell battery that could run a anywhere from 6 -12 hours ; It supported to internal hard drives, and an external one. The reaction to the laptop was weak because it was slow, it had no capacity for expansion, it weighed heavily, its price was expensive. It has been stayed 1 year and half on the market.

              Apple introduced the Macintosh Plus on January 16, 1986. The Macintosh Plus has an 8 MHz 68000 processor and an internal 800K floppy disk drive. It supports up to 4 MB of RAM. The Plus is a significant improvement over the previous compact Macs primarily due to the addition of the SCSI bus. Previous Macs did not have SCSI, thus making it more difficult to find a suitable external hard drive able to connect through the drive port, the printer port, or the modem port. These drives are considerably slower (as much as 4 times slower) than external SCSI hard drives. The Macintosh Plus is a very important computer in the history of the Apple Computers. It set up many of the standards that Apple followed for over a decade going forward.
