Well, i now have my case from Corei64, still waiting for the TiPi to get here.

The case came with a few extra parts, spacers of some kind? I have a big "L" shaped part, a little "L" shaped part, and a part that looks like a "1" with a small "F" behind it.

No idea what all those are for.

 

Also... I have been worrying myself almost sick, dreading the thought of improperly hooking up the TiPi <-> Pi wiring and frying something....

Could anyone please post really good, detailed steps and pictures of the whole process of mounting the case, and hooking up the wiring from TiPi to Pi. (I have the 3B+ model coming)

 

A good video (with out turbo speed time lapse) of the process would be good too.

 

-------------------------

Also, i know that extra sidecars (like sidecar disk drives and disk controllers etc.) plugged in use up a little bit of memory, i.e. a ti with only 32k and ti xb actually has a bit more memory then a ti with 32k+disks.

Just how much more memory is used up by plugging in the TiPi?

Could some one please post the result of issuing the SIZE command from TI XB with only 32k+TiPi and nothing else installed?

Here's a video I made last year installing it in the Corei64 case, there is some speed up but you can pause it if you need some stills.  I took the liberty of fast forwarding it for you, feel free to rewind if you want to see what you missed.

You can see the results of the size command here.

The cables go on the PI close to the USB and Ethernet end of the PI. Only the extreme other end (Raspberry PI pin for +5v pins 2 & 4) is dangerous.

 

https://www.jedimatt42.com/ti994a.html  <--- The pictures here should be clear enough to stay safe.

 

The diagram at the bottom of this page should be very clear... 

 

If this diagram is at all not clear, please explain what is ambiguous so I can fix it.

Ok, so at the bottom of that page, just before the diagram, I had a high-hazard message: "Warning connecting the cables wrong can destroy the CPLD..."  

 

In practice, I connect them all kinds of wrong (rotated, swapped, rotated and swapped) all the time... it is just that +5v end on the PI that kills the CPLD... I have ammended that message:

 

Warning: connecting the cables to the wrong end of the Raspberry PI can result in destroying the CPLD on the TIPI board.
