The Mother of all Emulators for the Granddaddy of all Computers
Back in 1975 a small company called MITS released what was the first commercially sucessful personal computers. Based on an Intel 8080 CPU and shipping with only 256 BYTES of RAM (but luckily lots of room to expand) and programmed through either the myriad switches on the front panel and paper punchtape (you could also connect a dumb terminal to give you a nicer environment with a keyboard and either a screen or at least hardcopy printer) the Altair was a pretty limited machine, but it was the first computer that was both available to the general public and sold at a price that the public could afford.
I've recently come across an emulator for this legendary computer that seems to be quite good. Known as Altair32, it emulates a wide variety of different peripherals that were available including tape drives, disk drives, hard disks and even the first video card ever built. In addition it comes with a boatload of old software, so if you have acess to Windoze at all, you should check it out.
