In the modern day Windows is a power house, but that wasn't always the case. In this episode we are looking at the fraught development of Windows 1.0. During development it was called vaporware, it was panned in the press, roasted at at least one trade show, and even called... "eclectic". Through it all a vision in lime green would take form.

This episode we are taking a trip back to UNIX world. We're looking at IDRIS, the first clone of UNIX. It was supposed to be highly compatible, but use no code from Bell Labs. IDRIS ran on everything from the Intel 8080 up to the IBM System/370. There was even a version that could run MS-DOS programs. Sound too good to be true? Well, that may be the case.

In 1970 a little language called BLISS emerged from Carnegie Mellon University. It was a systems language, meant for operating systems and compilers. It was designed, in part, as a response to Dijkstra's famous Go To Considered Harmful paper. It had no data types. It used the most bizzare form of the pointer I've ever seen. And it was a direct competitor to C. Sound interesting, yet?

In 1961 Texas Instruments unveiled the Molecular Electronic Computer, aka: Mol-E-Com. It was a machine that fit in the palm of your hand, but had all the power of a much larger computer. This was in an age of hefty machines, which made the achievement all the more marvelous. How was this even possible? It was all thanks to the wonders of molecular electronics, and a boat load of funding from the US Air Force.

The Z4, completed by Konrad Zuse in 1945, is a computer with a wild story. It was made from scrounged parts, survived years of bombing raids, moved all around Berlin, and eventually took refuge in basements and stables. In this episode we will follow the Z4's early days, and look at how it fits into the larger picture of Zuse's work. Along the way there is looting, rumors, and even... IBM!

In 1933 Konrad Zuse, a German civil engineer, caught the computing bug. It would consume the rest of his life. According Zuse he invented the world's first digital computer during WWII, working in near total isolation within the Third Reich. How true is this claim? Today we are looking at Zuse's early machines, the Z1, Z2, and Z3.

Have you ever felt like a computer just refuses to work? Like a machine has a mind of it's own? In 1970 a hard drive at the National Farmers Union Corp. office decided to do just that. That year it started crashing for apparently no reason. It would take 2 years and 56 crashes to sort out the problem. The ultimate solution would leave more questions than answers. Was the hard drive haunted? Or was something else at play?

This time we are diving back into the Jargon File to take a look at some hacker folklore. Back in the day hackers at MIT spent their time spying on one another's terminals. That is, until some intrepid programmer found a way to fight back.

In 1962 Food Center Wholesale Grocers Inc installed a new IBM 305 RAMAC. That's when things started to go wrong. The faulty machine seemed to have a mind of it's own, and would spread chaos to grocery stores all around Boston.
