So here is my take and some back story...
I decided that I wanted to restore a real game on impulse. I am partial to Williams games, and I like the un-ordinary. So I pick up a Bubbles off of EBAY for $80. It is supposed to be complete but non-working. When I get there it is a complete game, non-working, with nice art but a bad CPO. I get it home and find out that it is actually converted to
and the supposed original boards/monitor are long gone. I then set out to find the correct components and it hits me, I'm in over my head for a first game for both costs and complexity.
Now I am not hurt on this purchase (yet) but I did start looking for a different game with less issues for a first. My goal was to get
educated on a particular game type (Williams) and go shopping with the knowledge of what was correct for parts, and what to expect for costs to restore.
I picked up a Moon Patrol at auction. I
knew before I bought it what the components on the inside were to look like, and I took cheats along with me to verify. I wanted to start with an un-hacked game to learn on, and that is what I bought. The MP was a bit hacked, but it made it cheaper, and I knew it was hacked before I bought it.
What I suggest to you is to do EXTENSIVE net research first before pulling the trigger. Expect the worst... likely the wrong monitor, hacked harness, bad power supply, etc. learn what the components for a DK look like and what the costs to fix each are. Take cheats with you to help insure that you identify the parts correctly. know what the sum of expense you can stand is, before you go to look. Be prepared to WALK AWAY from the deal if it falls outside of your comfort zone for price or complexity.
I used to use these rules when choosing a car to restore, and I assumed that games were simple, and failed to apply these rules to the first game I bought. I have learned over the past couple of years that there will always be another DK or whatever for sale if I'm patient, and I waited on the SECOND game until the right game came along.
