CPU

For owners of WPC89 without a security chip and WPC95 :

This board follows the original layout, with only the battery location changing (using a CR2032 button cell) and the addition of an anti-reset footprint.

The components are mounted on supports and identical to the original board, but they use HCT technology instead of LS, which reduces power consumption from 500mA to 200mA.

The price does not include the 6809EP microprocessor, ASIC, or ROM, but these can be provided optionally based on availability upon request.
