HIARCS 3 (0.3) Source code

This is the source code of HIARCS 3 (known as version 0.3 to avoid confusion with commercial HIARCS versions of the 1990s).

This source code dates from March 1981 and is the source code of HIARCS 0.3 as submitted as an O Level project at Mount Grace School, Potters Bar. The source is in the Basic+ language and ran on a PDP11/70 located in Hatfield Polytechnic Campus, Hatfield.

The source is on a dot matrix print out and the pages have been scanned in and are presented here as jpeg images. Click on the image you want to see. The b listings are a landscape view of the listing page where some of the lines were too long.

Resurrect HIARCS 0.3 and win a Prize!

I must admit to be intrigued to know if some one could get this source running again on PC or Mac. There are a number of prizes on offer for anyone who can successfully get this oldie chess program running again!  You can read more about the Resurrect HIARCS prize competition here.

"HIARCS is much better positionally than Deep Blue." - Garry Kasparov 1997 (after game 5 of the rematch)

World Chess Champion, Vishy Anand, used "Powerful" HIARCS machine in preparations for his 2010 world title match with Super GM Veselin Topalov

"This level of service is one other big reason to buy HIARCS." - John Jackson, November 2009
