Christer from Sweden built an Eduardo Casino designed KIM-1 replica. And as we know, the 6530 replacement is an issue.
Not only for replica’s also for broken original KIM-1s.

So he designed his own, more compact original looking adapter.
He created this adapter because I wanted something that would work and look a little more unobtrusive than the other adapter boards that are available but still look somewhat genuine (no FPGA). The design is inspired by the Corsham 6530 replacement board but made way smaller by using SMD components and stacking the 6532 on top of the adapter board.

A newer design promised to be much more compact.

MOS Technology started development of the 6530 RRIOT very early after/during the 6501/2 development. All in 1975.

The first version of the Hardware Manual has this mention of KIM and TIM:

The KIM and TIM were mentioned as Keyboard and Teletype Input Monitor, indicating these are the 6530-002 and 6530-004 RRIOT IC’s. Indeed these ICs were sold later on.

The KIM-1 computer was developed later, with the KIM RRIOT and the 6530-003 audio cassette interfacing ROM using the KIM 6530-002 RAM and I/O ports.
The KIM-1 was not called -1 as first version, but for the 1K RAM included on the computer.
First shipping of the KIM-1 started in early 1976, then the first articles in the magazines and advertisements appeared.

So KIM is the 6530-002 RRIOT IC, KIM-1 is the computer around the KIM and 6530-003.

Before I saw the last revision, Rev G, I had never seen an original KIM-1 with IC sockets. All ICs were soldered right into the PCB.

Now I have a KIM-1 Rev G and a photo by Dick Dral of his KIM-1 Rev G with white IC sockets.

So the last iteration of the KIM-1 did have IC sockets.

Not only did Rev G come with sockets, they used not only white sockets, black ones too (Thanks Santo Nucifora).
