[Coco] Re: CoCo 512K EEPROM+External Controller Walkthrough (Final)

[chadbh74]

   Well my friend you have first dibs on the set I hope to build and test
   today. Ron is next in line for the other one.  The cartridge board I
   already have assembled has a slightly tarnished spot in the silk print
   (my fault) where I wasn't paying attention and installed the jumper
   posts on the wrong side of the board....ughh.  I had to go back and
   extract them and reinstall.

   I will keep you posted.

   Sounds pretty reasonable to me. :)
   If you're considering a medium run with OSH Park, PCBCart is worth a
   look.
   They are who I've been using for the SDC, RGB2VGA, composite boards,
   etc.
   For runs of 20 or more, you'll likely come out ahead with them, and be
   able to get
   real plated edge connectors (instead of ENIG finish) for the board. No
   "nibbles" around
   the board edge to file off either.
   Just a thought.

   bucks for this setup sounds a little pricy to me when I try to put my
   foot in the other shoe so to speak. However, with cost of the PCB's,
   parts and time spent with assembly it seems more reasonable. If there
   develops a significant demand for these I will do a medium run with
   OSHpark to get the PCB prices lower. I'm also starting to source more
   and more of the IC's and components from china wholesalers. A year ago
   I ordered a spool of 5000 x 1K ohm SMD resistors for $12.00 thinking it
   was cheap, why not, even though I would never use them all. Now, I'm
   finding more and more need for them with projects like this and buying
   in bulk becoming more appealing.

   and desired and I'm all about having as many options as possible with
   new hardware/software. I'm certainly willing to provide such options
   where practical.
