Thanks for the feedback guys,

So, ECU swap and start-up went fine. Idling was too high and car ran
rich after the swap ....SO  while not a "brick" the ecu is NOT "good to
go", but maybe good for a spare OR a core on a rebuilt one.

I did get a "shoebox electronics" ECU monitor from the seller though,
along with other used parts, a Throttle Body and  AFM
