COMPUTER SYSTEMS that existed before the dawn of Time are getting support from a team of developers for simulation software for 20 different machines in a bid to preserve the computing past.

The Computer History Simulation system is focusing its aim on SIMH, a portable multi system simulator which currently has support for a number of ancient machines.

Those include Data General's Nova and Eclipse; DEC's PDP-x and VAX systems; GRI's GRI-909; the IBM 1401, 1620, 1130 and System 3; Interdata's 16b and 32b; HP's 2116, 2100 and 21MX; the Honeywell H316; the MITS Altair 8800 (8080 and Z80 CPUs) and Scientific Data Systems SDS 940.

The group has also created Windows executables for all of its SIMH simulators and has available a number of software kits and tools. This picture below is a screen shot of PDP-1 simulation under Windows.

Authorities in several countries raided Megaupload recently, shut down all of its services, seized hundreds of servers and arrested several of its executives on criminal charges.

Do you think the move was justified?
