Kaypro II

Kaypro II

The Kaypro II was the first computer released by Non-Linear Systems, in 1982. Non-Linear Systems was founded by Andy Kay in 1952. But they didn’t make computers back then, they made digital multimeters. You see, Andy Kay is the inventor of the digital multimeter

The Kaypro II is unusual because the entire case is made out of metal. Kaypro’s computers were an extension of their test instrument design philosophy: rugged, reliable, reasonably priced, looking more like instruments than the creative, communications (and business) tools that they heavy.

The Kaypro II didn’t need to much work to get it going.

Added a Z80 SIO chip, clean the heads on the floppy disks and it now boots into CPM.

Very happy with this machine.

 

The Keyboard needs to be serviced.

I need to get a RJ-11 connector and fit.

Also  pads need to be re- done on the keys them self, have ordered the pads.

 

— UPDATE 2019 —

Keyboard restored

Have now replaced the broken RJ11 Connector

 

Replacing the felt pads on the keyboard and keyboard is fully working once again.
