Hi QLers, the ZX8301 is the 'Master Chip' of the Sinclair QL Professional Computer. Its purpose is documented in the Sinclair QL Service Manual. See:
http://www.sinclairql.net/srv/qlsm1.html#s1-p6 The chip designed by David Karlin and manufactured by Plessey. See: http://www.sinclairql.net/story/The_long_lost_interview_with_David_Karlin.ht m There are two known editions of the chip, the CLA2310 and the later CLA2345. Their mask differs. Way back in May 2014 I explored the die of a Sinclair ZX8301 CLA2345 chip with my newly acquired BRESSER MicroSet microscope. Another QLer is currently exploring a CLA2310. This motivated me to review my work and publish the material (both video and stills) I've shot using the microscope.
