Icons turn 40

 Icons turn 40

Xerox Alto personal WIMP computer from 1973:
Speed 0.3 MIPS
Memory Type Semiconductor (Si-gate NMOS)
Memory Size 64K - 256K
Memory Width 16-bit
Estimated cost  $40,000 (1973 dollars)
99% BAD HARDWARE WEEK: 10 years later XT was priced 10 times lower. With DOS and Basic in 16 colors. Yes, Windows 1.0 extension was announced too (but not released).
300 000 IPS is not bad at all. First defense system SAGE was only at 75 000 IPS
