The 4 layer board was only produced once, way back before the list had a 
problem with a mouthy troll and a server crash. There was also a situation, 
where a well meaning person, through an unfortunate set of circumstances 
had some major components go missing and a LOT of the 4 layer sets never 
got built.

Frankly, at 8" x 8" it was a very large, fragile board. The people that 
have them running will swear that the boards are fine (they are also the 
people flogging the mega-squirt system).

If you put out a request, you might find someone to sell you a complete or 
partial set. You had better be good at soldering, putting together 
programming tools, designing code, and be relatively self  supporting.

There are about 4 different TPU code sets available; the standard 
automotive set as it resides in ROM, the automotive set in assembleable 
microcode, the BMW set, and the one that you can easily put together to do 
the functions you need from the publicly available microcode.

Remember that the microcode set is dependant on the processor that you 
order. You can get either set from Freescale. The processor is in a socket 
(!) and either fit.

I have done a brain dump on a whole bunch of info on my web site. Some of 
it is specific to my project, but there is a bunch of general stuff there 
as well. See: http://www.chichak.ca:8080 for more info.

>Where can I find more detailed info?

On several occasions the list daddys were asked for some 
information/documentation/hints...well apparently if a job is hard to do, 
it should be hard to understand.

I have put a bunch of docs on my web pages in the references section, a 
good overview of the whole project is the section called 
"<http://www.chichak.ca/EFIsupport/TPUPN15B.pdf>Period Measurement With 
Missing Transition Detection TPU Function (PMM)".

Motorola/Freescale has put out a LOT of data sheets on every part of the 
processor and it is a hell of a lot of information to take in. Please feel 
free to ask.
