Junior Elektor, from base to full system

The Junior Computer hardware and software is described in detail in the books and articles, see there for details.

On the following pages the essential information about the different parts are described: circuit diagrams, articles, ROM source and binaries etc.
It starts with a simple SBC: the base Junior. And it ends with a complete floppy disk and video based computer: the full Junior.

Note that the Junior has the Elektor bus and could use a lot of the cards developed later for the EC65/Octobus, but memory layout differences may require adaptations. Study articles and books, lots and lots of subtle changes required in every step.

Thanks to many contributors, for ROMs and information! Philippe Roca, Philippe Roehr, Keith Robinson, Guus Assmann, the people at forum.system-cfg.com , VzEkC e. V. (classic-computing.de), Bram Prosman, Ian Lockhart. If forget someone, I want to thank you!

KIM-1 first clones

On this page early KIM-1 clones with the, at that time, available RRIOTS.
The KIN and SuperKIM are KIM-1s because they have he KIM-1 RRIOTs. The last two, the Scandinavian Digitus and a Conversational Voice Terminal Corp one have a PCB with similar layout and sizes, real KIM-1’s with the KIM-1 RRIOTS with newer or more RAM.

The KIN microcomputer
Conversational Voice Terminal Corp, Chicago Illinois

The KIN microcomputer

A portable KIM-1 clone. Used in gambling it seems. 6530-003 only. 1K RAM (2x 2114), 4K EPROM (2x 2716).
Original article on this website.
PDF of the design of the KIN computer

Conversational Voice Terminal Corp, Chicago Illinois

This one also popped up on ebay without much information. A KIM-1, PCB newly layout, 4K RAM (8x 2114 IC’s), for the rest a traditional KIM-1.

KIM Clone

A KIM-1 clone build by Bob Applegate of Corsham Technologies.

The idea was replace the 6530’s with 6532 and by careful memory decoding have the I/O, timer and RAM of the 6532’s appear at the same locations as the 6530-002 and -003. ROM is added with an EPROM.
Not an exact copy in dimensions , and the ROM has been changed/enhanced/improved with a xKIM Monitor by Bob Applegate (hex upload e.g.), though the original KIM-1 ROM should work also.

The result is a high quality build, and an exact KIM-1. With many extra’s

Available assembled and tested or as a kit. I have bought the Rev 2 PCB with essential parts from Corsham to build it!

And also bought the assembled Rev 5 with expansion connector, motherboard, Proto board, KIM Clone I/O and SD/RTC Shield.

This is a dream of a 6502 development system! The SD shield has a simple interface in the xKIM monitor to load and save files on the SD, which is a FAT formatted card, Fast enough of course and easy to exchange fiiles on a PC with a cross assembler.

What you find here:
