[Coco] "Historic" CD-i development systems...

The '340 has a TPU processor that controlls the peripheral items. 
There is a procedure to follow to initialize them and use them. 

As for the '060, I believe top speed was 66MHz. on that part. It too 
like the 6809 and all of Motorola CISC processors are two phase 
clock processors.
