Is it at all possible to do networking in SIMH's PDP-10 emulator? Turns out I need to reinstall TOPS-10. ;) So I either need to: 1). Stage TOPS-10 in SIMH then move to KLH10's KS emulator (seems to uses different disk format) 2). Install TOPS-10 directly in klh10 (How would I change tapes during runtime using KLH10?) 3). Not have networking. ;) Is configuring networking in KLH10's KS emulation the same as using it's KL emulation? devdef nib et cetera? Thanks!= If anyone has any knowledge of getting networking running over a DMC11 on a KS10 please let me know. I am just about to try adding the DMC11 to the KS10 emulation in SIMH. Unfortunately I fear this may not work. This is because I have it on good authority that TOPS-10 may have a driver for the very similar DMR11, but TOPS-20 does not have even that (or not directly anyway). I have no knowledge of TOPS-10 and would need help to get things working there. FWIW, DMC and DMR are the same at the programmer level. They are somewhat different at the protocol level -- DMC uses an older version of DDCMP and has some bugs in that implementation, especially in the "high speed" (1 Mb/s) version. But those aren't visible to driver writers, though they matter if you do your own DDCMP protocol implementation. paul
