There's a modified 630 that's been braindamaged specifically for military use. However, you don't need a 630 for this - a good old HP2621 or many other terminals lets you send a copy of the terminal screen to the host (for fill-in-the-form applications). About 8 years ago, there was a story in the San Francisco Chronicle about how hackers at Berkeley had broken into "the UNIX, a computer made by DEC", which was really abou this trick. It's probably less likely to bother you with a 630, assuming you run the standard terminal emulators which are owned by the system administration logins. -- # Thanks; # Bill Stewart, att!ho95c!wcs, AT&T Bell Labs Holmdel NJ 1-201-949-0705
