Memories! I raced briefly out of Boston, '76-'78 for NEBC. Biggish club around Boston for the day but only a few strong riders. Best TTer was Peter Mooney who was turning his focus to building bikes and starting up Belmont Wheelworks while I was racing. Some of the names you list are familiar but I don't recall seeing any of them race (though they might have been at Fitchburg, a race I watched).
Edit: and yes, we did grovel at the Richard Sachs bikes when they showed up!
