DDCMP over asynchronous emulated lines on simh 4.0

Which is one reason (of about four) that prompted me to raise the issues concerning the PDT-11/150 on this list not too long ago. I'm still kicking around some ideas with that particular release of E11 that I tracked down in my collection, but its slow going. Now the interesting question, for the problem that Jordi is concerning himself with, what release of VMS (early or later) would have supported networking that way? For example the campus network on (where else?) UC Berkeley was Ethernet all over, and supported VMS on the VAX systems they ran, and BSD (of course) but they also talked to the odd PC and a number of Macs. I'm not sure what terminals they used, since Cliff didn't note that bit of trivia. However to get outside of the campus he had to mind several lines some were dial-up and a few were leased, and those got connected to hardware for Tymnet. I'm just throwing stuff into a very blue sky here. -------- Incidentally all of today's problems are Dave's fault. Including that sneaker or shoe lace you broke Corey and the fact that someone's cat caused an expensive object to break. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

Its one of the many reasons why the UNIX community in those days, used to recommend using Able Computer's DH/DM solution. Which was 16 serial lines with full modem control on a single unibus board (and as described previously used DMA and had character buffering), The Able DH's actually could run at faster speeds than the DEC one did. Are you sure about Able? I can't remember seeing any such thing from them. Emulex did that, though. SC02 and various incarnations. It didn't have full modem control, but enough for the common use. Speed was better than a real DH-11 for sure, as well as just taking one slot. Really good and reliable piece. I never experienced any actual problems with DZ-11 though, but I totally detest the thing because of performance issues. (I probably have more DZ-11 laying around than I ever will use. DEC must have been giving them away for free...)

MAIL-11 Protocol specs

by tim＠sneddon.id.au

I definitely remember seeing something, although I don't recall where... However, Phrack Vol. 3 Issue 30 has an article titled "VAX/VMS Fake Mail" which seems to have some details. You can find it at: http://www.phrack.org/issues.html?issue=30&id=7 Regards, Tim.
