MCM/900 Maxi Switch Magnetic Reed

[snuci]

In honor of Chryos' Maxi Switch Magnetic Reed review, here is my latest project with the Maxi Switch magnetic reed keyboard. This is the younger brother to the MCM/70 (with pics posted here) and was three generations later built in 1979. It still runs APL as but most computers of the era had BASIC as their main programming language. There aren't many of these either.

I have wondered if there is any connection to CRC as perhaps it turned into Maxi Switch later on because of the similarities. Purely speculation on my part.

Very nice.
I also now have a desire for a 2u Enter key labeled EXECUTE.
