I linked A1200 to A2000 with parnet, and it worked fine yesterday. Today, after trying all the possible combinations of UNIT 0, UNIT 1, etc. it doesn't work. Cable is good, it works between A2000 and A4000, so the problem must be in A1200..
Is there some way to thoroughly test CIA chip (other than this)?
