Recently I acquired a ‘white’ KIM-1. Most revisions were made of green PCB material.
Rev D and Rev E were also made in blue.
This one is a Rev D with a ‘white’ PCB. The KIM-1 is working as you can see.
The ‘white’ KIM-1 as received, working but awful to look at
But the previous owner did some horrible work on it. Most IC’s were unsoldered and placed in some kind of IC sockets. The desoldering did quite some damage to print traces.
Many traces were covered with solder. Solder remains everywhere, very dirty brown spots of solder resin. Wires soldered on the connector, and the A-K wire on the board itself.
The biggest crime is the keyboard that was handmade on experimenters board. With quality switches, but with an awful appearance. It works, but it had to go.
With the DIY keypad method, based upon the work of Eduardo Casino and Pete (peo2000) I replaced the keyboard with an acceptable replica. Not too easy and tidy since the print traces were damaged
With a replica keyboard, wires and excessive solder removed and a good clean with alcohol and a brush the white KIM-1 may join my collection.
