I think I mentioned it in the other thread. The original Tera was a 286 based board and designed to be programmed in Borland Turbo C. It used some custom PLAs and the sound system was my contribute, 2 YM2203s, but set out in stereo with a speech d/a port. This was the system where I mentioned spending a week up at Doug's house and losing in the pinball bets. If you ever seen the arcade game Qix motherboard set, that was his design. (as a point of trivia, all hardware and software programming for Qix was done in Nocal, it is not a Japanese game whatsoever)
I found my schematics to it so I will post them eventually. One cannot build without the PLA code anyways.
Tera ][ is my own version. It is designed as a more generalized system. I also used the 65C02 because I am much more of a fan of that chip, I use it whenever I can. For example:

I was developing an automated test fixture for a past job that sold DVD and TV entertainment systems for SUVs.
One main project I am working on right now is a pinball. There was the Bally home Fireball pinball series. They used a custom CPU which cannot be gotten today (F8 with embedded program sets). My concept is a piggyback board with a new CPU.

Here is my early test configuration. It will revamp into the newer system.
The newer system is designed as a more general axe and tool for things. The specs are as follows:
4 MHz 65C02
32K main program, 24K RAM
4 megs banked ROM 4 megs banked RAM
USB port
Pinout follows the WDC developer module pinout.
TIDE design capability.
So the end result is a fairly low cost general purpose system I can use for a wide variety of tasks. It won't handle high end polygon graphics games without some serious finagling and that is time I don't want to spend For the purposes I want, the pinball, the airplane controller, Tera ][, it is perfect.
There are some past game projects I still hope to bring to life. For example, Thunder Shifter. That was a Romstar redemption game that never saw the light of day. I had a full wiring using our poker boards and a test fixturing made and some code done (which is lost, unfortuantely). I still have my notes about the puppy though and I got some new ideas towards. it. It is a non-video novelty ticket dispensing game.
I do have an arcade I've been working the past 11 years as a test bed so that is where it is scheduled to test at first. It is located at an amusement park in Orange County.
EV: Fully agreed. A large tream with the financial remuneration not being there isn't worth it and you guys aren't doing this as arts projects but as working concerns. 
Also, anything written before the American version would not have that chapter. It was more for new US programmers, I guess....
