> It's interesting that it was a bad 7430 in [your RK11-C].  I find that for equipment of that vintage, my usual suspects are failed 7474s and failed 7440s, probably 80% of the total.  Behind that, it goes 7420s and then maybe 7430s.

Looking back over my repair log, my totals just within the RK11-C were:

2x 7430 (M119, M795)
1x 7420 (M141)
1x 7401 (M149)
1x 7400 (M203)
