RAM+ for TRS-80 Model 100

Overview

 

The RAM+ is a modern recreation of the Cryptronics RAM expansion for the TRS-80 Model 100. It uses modern components rather than being a direction reproduction of the original. It supercedes any RAM installed on your M100 and provides four 32K banks for 128K RAM total. In order to use this memory banking functionality the RAM+ 'driver' ROM must be installed.  You could use your own EPROM with an appropriate adapter for the M100s unique ROM socket, or a REX+. The easiest way though is to use the Dial-A-ROM for the M100 (MT) which has the RAM+ driver built in. The RAM+ firmware provides a menu for easy switching between banks, transferring files between banks plus much more.

NOTE: WILL NOT WORK ON THE T102!
