Wow, you have gold on all your PDP-11 modules? Maybe those old cards are worth more than I thought. :-) I have a number of TRS-80 Model-I's with the Expansion Interface and they all work quite well. I spent more time cleaning edges connectors on my daughters Nintendo than on the TRS-80. And, of course, like the PDP-11, today it is mostly done with emulators anyway. bill -- Bill Gunshannon | de-moc-ra-cy (di mok' ra see) n.
