From a notice in Computerworld:
The Intel IMM 4-90 is a high-speed paper tape reader for Intellec 4 Model 4 and Model 40 microcomputer development systems.
The reader transfers data asynchronously at 200 char./sec. This allows 4,096 bytes to be loaded in an Intellec 4 program memory in less than 30 seconds.
Hardware compatibility is provided by the reader's interface cabling and by the Intellec 4 IMM 4-60 I/O module option, which includes reader input and output ports.
Intel also produced a IMM 8-90 tape reader for use with their 8008 development system.
