Hi, John! Are any of these boards left? If yes then I will take one. And can I be put on a permanent list for new boards?

The only issue I have found is that the 3 digit bus clock frequency (PHI) is always 1MHz less than expected. i.e. 10 MHz Z80 shows 9.99MHz, a 8MH 8086 shows up as 7.99MHz.  The construction notes and details about the board can be found at the bottom of this page:-

This time I had 4 production board ordered from China to test first.  That way I'm not sweating with a backlog of boards that may have an error!  This will be my approach from now on.   Also in the works is a "V4" version of our old tried and true  16MB static RAM board, two GAL, no daughter board, SMD RAM 8 or 16MB RAM, with adjustable wait states. "The last S100 bus RAM board  you will ever need!".
