There are a few modern LCDs that can make use of opt B if your unit has it. I think I have a pattern gen card and one low end acquisition card. Else the chassis are empty. The difficulty with the 1670x is the cards (acquisition and scope, not pattern). They form corrosion under the runners. I had 10 or so cards go bad over a 5 year period. All now have visible corrosion. I'm slowly working my way through removing the runners, fixing the corrosion and repairing damaged traces. There are no schematics but there is a very helpful active repair thread on eevblog. In my personal machine my second scope card passes diagnostics but totally fails calibration. Otherwise the diagnostics are pretty good but they don't run at boot up so most sellers have no clue how to run them. Try setting up a distance based search on eBay. I suspect something will show up given a few months patience but if it includes cards there is a very good chance they are bad. Don't ever buy a card on eBay "for parts or repair" unless it's dirt cheap. Good luck
