 The repository includes an emulator implementation of Thingamajig with a
-control program for the emulated punched tape reader and punch, and an
+control program for the emulated paper tape reader and punch, and an
 assembler and a disassembler, all written in FreePascal. It also
 includes couple of simple example programs for Thingamajig written in
 assembly.
