When setting the number of clocks taken by ALU operations to zero and cycle accurate bus cycles we appear to get a nearly 1.5X speed improvement over the stock 8088. This leaves no gaps between 8088 bus cycles which would normally occur while the ALU operations are completing. This may be the theoretical maximum speed attainable when all instructions and data use motherboard resources that use the 8088’s bus interface. When we try using internal memory for RAM and ROM which are not sensitive to the 4.77Mhz clock this speed boost should increase dramatically.

King’s quest also appears to run without issue!
