[Photos] MCM/70 - Controls Research Corp keyboard

Here is a small set of pictures of my MCM/70 computer. This computer is from 1974 and was very early in using the Intel 8008 CPU as the central processor. It also has some very innovative features but I know you guys only want to see the keyboard. The keyboard is made by Controls Research Corporation and features linear switches. This computer is too rare to dive in any further. There are less than 10 known in existence (I only know of 5) and this is the only one that is known to work.

In the last picture I can't help seeing a robotic face... Beautiful, of course.

This is a truly amazing piece of history. It has the processing unit, display, storage and input in a single unit. I hope to see more coverage of this on your site!

I finally added a post on my site for the MCM/70 after taking extensive pictures and testing it out. You can find my post here, if anyone is interested: The Micro Computer Machines MCM/70, the Canadian Holy Grail of Computing History

If anyone is curious about APL and how it is used, you can see me typing in an APL program and running it on the MCM/70 below. This was done so that an the behavior could be checked against an MCM/70 emulator that is in the works. The writer didn't know his output was actually correct, including the nuances of memory swapping and delays, screen glitching that is caused by this. Remember, this is from 1974 so the graphics aren't great :)
