IBM 5100 

One of the first ever personal computers, the IBM 5100. Not all that successful unsuprisingly with a starting price of around $9,000 to $19,000 depending on the model. You could have built a nice house for that amount of money in 1975.

The processor was a PALM (Put All Logic in Microcode), it was actually a circuit board rather than a small chip. IBM referred to it as a controller

The 5100 had a large tape cassette drive for off-line data storage and a small built-in 5 inch CRT. A BNC connector allowed the computer to be connected to an external display, i.e. TV set.

The 5100 used large magnetic tape cassettes for storage and memory could be expanded up to 64 KB. It was intended for use by engineers and problem solvers, but never really took-off in a big way.
