I do not have the terminal emulator software for mine. My recollection is that through the 4952, you can make an archival copy, but the process somehow marks the source disk as having been backed up. Does anyone know if it's possible to manipulate these disks in PeeCee-ish boxes? I don't know anything about the format, except that they probably use "1MB unformatted" floppies (i.e., formatted to 880K in an Amiga, 720K in a DOS box, etc.) These things are lots of fun, especially when you are trying to debug protocol bugs on sync modem lines. At Software Results, we programmed one to emulate an IBM Mainframe and I/O controller (SNA PU Type 5?) to test signon bugs. The real problem was having to send RR (Receiver Ready) packets. There was enough RAM in the HP to get as far as the SNA BIND, then it just looped. -ethan -- Ethan Dicks, A-130-S Current South Pole Weather at 19-Mar-2004 00:09 Z South Pole Station PSC 468 Box 400 Temp -73.8 F (-58.8 C) Windchill -102.1 F (-74.5 C) APO AP 96598 Wind 6.9 kts Grid 135 Barometer 680.5 mb (10607. ft) Ethan.Dicks(a)amanda.spole.gov http://penguincentral.com/penguincentral.html
