We were a lean operation with just 5 of us full time folks. If you called with a technical issue about any of our products, not just the bigboard, you talked to me. Sometimes I might be at lunch or in a meeting so the secretary would take a message and I'd return the call.
I'll admit that the names of you fine folks out there who talked to me are gone from my memory (I was always bad a remembering names) but at the time, I could remember the issue you were having so even if it took several back and forth phone calls I'd get you going as quickly as I could. Most times it would be a simple 'IF this, THEN that' type of call.
I designed several S-100 boards as well as a memory card for the Southwest Tech 6800 machine. I did not design any part of the Big Board nor our ZRT-80 terminal board but I knew them inside and out and could handle any "black magic" (my term for when a board acts opposite from what it should be doing) that arose. Sometimes a big customer would need a special hookup or such and I'd dive into it.
I wrote the article "Big Board Fixes that appeared in Micro Cornucopia #9 page 8.
I hope that this helps and as a new member, I am sure that I should get beat with a wet noodle for hijacking this thread. IF so, please guide me to the correct place/method.
