Ramworks

The Ramworks card, also known as the Ramworks I or Ramworks Basic, was the first RAM card produced by Applied Engineering that allowed Apple //e users to have more than 128K. Boosting the Apple //e to a minimum of 256K all the way to 1 MEG, these cards are fairly prevalent in the market due to the large numbers which were sold. All Ramworks cards also included the standard 80-column / 64K card built in.
Diagnostic software was part of the A2/A3 Appleworks Expander disks.
