This is an educational / training kit for the 6802 CPU, but can also be used as a CPU board in a Motorola EXORciser development system. It has an hexadecimal keyboard and a 6 digits LED screen.
|
||
|
||
The memory size is of 256 bytes plus an optional 1k. The first 128 bytes is in the MC6802 processor and is for user programs. This can be disabled with a wire link if the additional buffers are installed at the edge connector.\
|
||
The other 128 bytes is the MC6810 which was used for the stack and system variables.\
|
||
The two 2114 1k x 4 static RAM chips weren't included in the original kit but were to be bought as an option.

Thanks to Emil Sarlija for most of the info.
