[Coco] Back to the COCO

[Bill Gunshannon]

Funny you should mention that.  After seeing the comment about the COCO3 not having the 12v
required by the old floppy controller I got to wondering if it might not be better just running them
off of wall warts anyway.

If you could, send me a private email with your real mail address and I will see if I can dig up
boxes. (won't fit in even a large flat rate box! :-( )  Feel free to pull out any chips you suspect
and put in sockets.  I will gladly pay for the repairs as long as it doesn't end out exceeding
the actual cost of a new one.  :-)

And now another question for you or any of the other serious COCO hardware guys.
The MPI apparently has no more buffering than the cartridge port itself.  The Glenside
IDE has two open ports but also has no form of buffering either.  Just how hard would
it be to make something like the infamous Y-cable on a circuit board only with buffering
to protect the COCO from damage?  Getting PC boards is easy anymore with sites like
OSK (I have a handful of the cartridge boards and that is how I my Drivewire).  Is it
reasonable?

Hi, Bill.

That sounds like a plan, and you may even take out the transformer of the broken one too. I power my coco's with a wall adapter, so I do not need the transformer.

I do need to tell you that the only way to tell if the cpu is dead is to take it out and replace it with a known good one. The fact that most of them are soldered directly to the board and removing them without harm is practically zero. I do have a couple of 6309 which are pin compatible and function the same. Those cpu's goes around for 8 to 12 $.

If the GIME is shot, then that is an other animal to slaughter. Those can only be replaced by existing chips from coco3's that are broke but still have a good GIME.

The pia's are still to find on the net.

So lets hope it is just a minor problem.

OK. let's try this....

How about if I send you one complete broken COCO3 that would be yours
to keep and include in the package two additional broken COCO3 circuit
boards for repair (assuming reasonable in both cost and needed work)
and return? Not shipping the two additional cases (and the
transformer) would reduce the cost. Doable?
