The SUPERKIM is a neat little board, based on the KIM design, but with a real lot of enhancements. It uses the same 6530-002 and -003 chips to get the KIM software the same keyboard And connectors. But unlike the KIM all ICs are on sockets, free sockets are already provided for 6 more 2114 to get 4 K of RAM (like on the SYM) four sockets for (E(P))ROM (up to 16 K), four sockets for 6522 VIAs (one already in place), a interrupt priotity logic, buffered busses, wire warp connectors for almost anything, complete memory decode, and last but not least a huge prototype area and a 5V and 12V regulator, so you only have to add a transformer, instead of designing your own PS. And the LEDs are already atop a seperate PCB (like the keyboard, but here is no difference to the KIM), so a 'distant' mount of keyboard and display is easy. On the backside, the _list_ price of 395 USD was almost twice the street price of a KIM and in the same region of the AIM street price (~400 USD in 1978/9). Shure, for a pure controller system, you don't need the ASCII keyboard, ASCII display and printer, but instead more I/O and interrupts, but the price was still impressive - I don't know if they sold a lot, but I guess, since the company had payed advertisements over more then one and a half year.
