I'll take that challenge

[dogwrangler]

I would be happy to toss in my ideas and experience in debug and repair.  First, I have to say I am new to this forum and don't yet have a machine to tinker with.  However, I have spent years (decades) in computer design, test, and debug (can't help much with the relay / logic based machines).  I have looked over some of the schematics for the IGT 2000(?), but not in great detail yet.

Just to get the ideas going.  Has anyone tried burning a "test program" eprom to replace the existing game / program (not sure of the common term) eprom in the system?  I have read the IGT comes with some form of self test, but am guessing this is not sufficient for folks to debug what the issue is.  A special test prom could tell the computer to do some very basic steps like slowly walk through each address and data line so you could see them change with a volt meter.

What kind of test equipment do folks have (light bulb, volt meter, scope, ICE)?  What are some common symptoms / issues do you see?

This is a fun group and I hope I can contribute.

Cheers,
