Digital HiNote 433

Digital Equipment Corp was famous of their mainframe computers, Unix workstations, Alpha processors and many ARM technologies, but not much of PCs. Digital manufactured PCs in their last years in 1990s, when mainframe and high-performance workstations were not selling well and DEC had to sell some divisions to other companies. This notebook is one of DECs PCs, a low-end small computer which could be used as for example office machine. It has grayscale LCD, 486SX 33MHz processor and small amount of onboard RAM expandable by modules. Digital made HiNote line of notebook computers, later it was continued by Compaq and then HP, as in 1998 Compaq bought remains of DEC, later being joined with HP.
