Description

This is the custom Sinclair ZX8301 ULA chip used within the Sinclair QL home computer to control video display, memory refresh, bus controller and ZX8302 register address decoder.  It is identified on the Sinclair QL motherboard as IC22.

Known as the master controller, this chip is a common cause of lack of output to a teleivison / monitor.

This is the plastic version of the chip, in 40-pin side-brazed DIP.

This is the later CLA2345 version used by the Sinclair QL, which was also the version used in the ICL One Per Desk (OPD), Merlin Tonto and Australian Computerphone computers which were based on improved Sinclair QL hardware.

Fully working and in excellent condition.
