Custom Instrumentation Solutions for Scientific and Engineering Challenges

The IDL Museum of "pre-Apple ][" Microcomputers


We have been in the game of connecting small computers to instruments since 1974.  In the first photo at the right are 3 microcomputers in the IDL cabinets that date from about 1977 or earlier.  Each was used to control and collect data from scientific instrumentation. 

At the upper right, you will see memory boards: a 4K (4096 bytes) semiconductor static RAM board and a 4K "core" (magnetic) memory board. 

In the lower image is a DAQ board built in the IDL.  At that time, it was not cost-effective or easy to generate single printed circuit boards, so the technique of "wire-wrapping" was used for point-to-point connections.

More "pre-Apple ][" computers, interface boards, and peripherals like acoustic modems and paper tape readers are housed in our "antique" cabinet.
