> What is that T11 CPU that I see in game units like APB and Paperboy?
It's a DEC T11 processor, AKA DCT11. It's roughly a single-chip PDP-11/05.
The bizarre thing is that they switched from the MC68000 and MC68010
used in earlier games to the T11, which was lower performance, more
expensive, and had fewer development tools. Even some of the engineers
who were there at the time have not been able to give me a satisfactory
explanation of how this happened.
It's also somewhat bizarre that they used the MC68010. Apparently that
happened because Motorola sales people lied (that's their job), and
claimed that Motorola intended to offer the '010 in speed grades at
least as fast as the '000, and for less than a 10% premium. If that had
been true, it would have been reasonable, but the '010 offers so little
performance benefit for non-virtual-memory systems that the actual 2-5x
price multiplier was unacceptable. And they never actually shipped
'010s rated for more than 12 MHz. And the timing on the 12 MHz parts
sucked.
