This directory contains the instructions for building an internal memory expansion of 256, 512 or 1024 kilobytes for the Commodore 128 or Commodore 128D computers. There are different versions of the documentation, and some software to test the memory expansion.
Don't forget to look for prlink in /pub/cbm/transfer. It is a transfer system for PC or Amiga and C= 8-bit computers. It supports also this memory expansion.
