THE PLAN (Step 2): Well the first thing we need is a piece of Vector Board, about 4" x 4" or about 10 x 10 cm ( Do not buy any cheap crap off of ebay.. It must be FR-4, glass-epoxy ).
|Vector Board before for clean up|
I need cut 2 holes in the board about 2" x .5" (Figure 1), or you can use a DB25 punch if you are lucky enough to own one, $$$$. I cut the two holes with my Dremel mult-tool, but it is very hard to control, I now have to clean it up, any way, with my Dremel. If I had the right blade for the rotary tool it would have been easier. Then I need to mount the adapter plate(s)(Figure 2) to the Vector Board and the DB25(s) to them as well.

The next thing is to mount the three 16 pin IC sockets, a little dab of hot-glue, or crazy glue and that should do it. But remember to leave room for the 4 pin Molex connector that is common on disk drives, and fans, Molex Part Number 15-24-4441, Molex Specification Sheet, and a relay that control the panel lamps.
I really like this relay module I found on ebay (Figure 3) and the cool part is I don't have to build it. There is all so a 2 channel module as well. BTW they are cheaper than I can build them..lol
Now the only this to do is break out the Wire Wrap stuff and wire it up (Figure 4).

|I am having the adapter plates made for me. Let me know if you think you can use them. I might get a small run of 100 made. My guess is they will be about 5 to 8 bucks each.|
