When attempting to save a game of Zork running under 4.1bsd on our Vax 11/750 I get the message "EMT 0345 caught" This appears to be a trap for a customer-reserved instruction, whatever that is. Can someone tell me what is going on? Is there an instruction on the 780 that isn't on the 750? Any comments would be welcome. Mark Callow qumix!msc
