The PLCC version of the 68HC11 is the one that you want. The part number from R.S. is 265-853 and in the July 97 - October 97 catalog it cost 7.50 pounds + VAT. This price has no doubt increased but the stock number should be correct. The 32K RAM I (...) (26 years ago, 6-Oct-98, to lugnet.robotics.handyboard)
