KIM Clone User Manual
Revision 5 and later Boards
Introduction
Thank you for buying our KIM Clone board, which provides an almost identical look-
and-feel to the original MOS Technologies KIM-1 computer.
This board should be very compatible with the original KIM-1 but is not exactly the
same, so there might be a few programs that won’t work on it. However, we’re kept
the hardware very similar and preserved the entry points to all the major
subroutines in the KIM monitor. Some functionality has been removed, such as the
cassette interface, so any code that makes direct calls to cassette storage/retrieval
functions will not work.
Overview
The KIM Clone has a lot of features packed into it while still employing a fairly
standard design with commonly available parts.
•
RAM from 0000 to 13FF. The original KIM-1 had only 0000 to 03FF.
•
EEPROM from 1800 to 1FFF containing a modified KIM monitor.
•
6530-like I/O, timer and RAM like the original KIM.
•
RAM from 2000 to DFFF.
•
Either RAM or EEPROM from E000 to FFFF.
•
Vectors can point to either the original KIM monitor or your own code.
•
No cassette interface for program storage.
•
The spare 6532 has a header for connection to a Corsham Tech SD Card
System.
