The ILLIAC II computer was disassembled roughly a decade after its construction. By this time the hundreds of modules were obsolete scrap; many faculty members took components home to keep. Donald B. Gillies kept 12 (mostly control) modules. His family donated 10 of these modules and the front panel

Donald W. Gillies, the son of Donald B. Gillies, has a complete set of documentation (instruction set, design reports, research reports, and grant progress reports, roughly 2000 pages) from the ILLIAC II project. He can be contacted for further details about this computer. Most of this documentation

The ILLIAC II project was proposed before, and competed with IBM's
Stretch project, and several ILLIAC designers felt that Stretch borrowed many of its ideas from ILLIAC II, whose design and documentation were published openly as University of Illinois Tech Reports. Members of the ILLIAC II team

Mersenne primes and found three new prime numbers. The results were immortalized for more than a decade on a UIUC Postal Annex cancellation stamp, and were discussed in the
