Hello! Sorry for stupid question, but i can't understand why i get the "error activating transport SMTP" message when i try to send a mail to some host in HECnet, using DECnet MAIL utility and address in HOST::USER format? I have MultiNet installed, but i planned to use it only as gateway to HECnet communication, and don't want to use SMTP server on this machine. SMTP server not now disabled . I 've read that DECnet MAIL uses Mail-11 protocol, so why i get the error messages about SMTP? Thanks, Igor P.S. OS - OpenVMS 8.4, DECnet phase IV, Multinet 5.4. Communication by MAIL between users on same host works good.

Problem: I can't recall the website for the US based users group for VMS

by gregg.drwho8＠gmail.com

Hello! Problem, this computer suffered an attack of typical Microsoft issues regarding its OS and required an installation of itself back about a month earlier. I ended up loosing my bookmarks. One of them was for the US based offices for the users group for VMS. As I recall and en examination of the form used to create the licensing string for VMS it requires that name. It also needs the member number from the group. I recall creating one for a kit that Sampsa has someplace last year, but I never managed to launch the Alpha emulator on any of the approved operating systems for it. Now I'm ready to try again with the VMS kit I have here someplace (it presupposes that I can find it, but I do know that the image can be downloaded...) and running on the SIMH Vax setup using the instructions on the site that the SIMH one is linked to. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

Does anyone have any reading material on how to figure out if the CIS microcode is installed ? Huh? That's a J-11 based board, and I'm pretty sure the CIS option for the J-11, while planned, was never actually shipped. It would have been two additional chip carriers on the bottom side of the big white J11 multi-carrier chip. The only ROMs on a KDJ11-Bx board contain the boot/diag code, not microcode, and conversely, the only microcode on a KDJ11-Bx (or any J11-based board for that matter) is in the microcode ROM, which is a part of the "control" chip, which is one the two chips on the J11 multi-chip carrier itself. No microaddress lines or any other internal state machine stuff is brought out to the pins of a J11. (sorry!) You CAN, however, get a CIS option (if you can find it!) for your 11/23! I too would love to mess with CIS a bit; I've never done so. I have two CIS option board sets for my 11/44s but have not yet installed them. -Dave -- Dave McGuire, AK4HZ New Kensington, PA The node PLUTO:: is a PDP-11/23+ with both CIS and FPU running RSTS/E.

You would be hard pressed to know if the system running (and connected to HECnet) was the real one or not! COBOL was the reason that CIS was designed for the 11/23+. Other languages can also make use of it. One that comes to mind is DIBOL. -Steve

Any reasonable modern FPGA is way faster than a 1980s era bipolar ROM, so modeling the interface timing should be easy. And level conversions should be doable. So a sort of daughterboard? That's a good idea. I'm pretty sure the F11's manuals are out there, but I haven't gone digging for them. From that, and possibly even just from the KDF11-Bx schematics, one should be able to glean the important parts of how to interface to the microinstruction and microaddress buses. Then all we'd need is a copy of the actual code. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Well, had it been that easy, the market would have been flooded with CIS options. :-) Johnny

Yep, the information there is wrong. No CIS for the J11. The only CPUs that ever got the CIS was the F11 and the 11/44. (Now I'm sure someone is going to point out the 11/74 CIS option, but it was never sold, even though I've heard that at least one prototype was done.) Okay, I'll check the 23Plus when I get home. Might get lucky there and be able to have a play with it there. On topic, seems to work in the quick test (sadly had work to do at home) I did last night which was a couple of memory fills so that's promising. Right. So no CIS for 83/94, but there is for 23Plus. Right. Thanks for the straightening out :) No problem. Oh, and I saw some additional discussions about the CIS option for the F11.

The M8190 is indeed the 11/83 and 11/84 CPUs. That's a J11 CPU. There is *no* CIS for this CPU. I thought you were talking about the 11/23+ and 11/24 in my first reply.

FAAC Best acronym next to our old one of FACOM which was changed when someone heard a .jp accent saying "FAKKUM" to one of the clients *G*). No clue how it ended up in Adelaide unless they were doing defence contracting. Yeah really! But, a great score either way. You CAN, however, get a CIS option (if you can find it!) for your 11/23! I too would love to mess with CIS a bit; I've never done so. I have two CIS option board sets for my 11/44s but have not yet installed them. Nice! (tm) .. got a photo's of the 11/44 option? Not yet, but keep after me about it and I will photograph the boards. Really wondering about the /23Plus. If the option for it is just PROM's that should be pretty easy to reproduce. It won't be at all easy to reproduce. They are MICROMs. The F11 CIS option is one of those multi-chip carriers, but for CIS it is two 40-pin-DIPs wide, and contains six MICROM chips. These are bipolar mask-programmed ROMs with an (I think?) undocumented interface. I would be more than a little surprised if anyway, even someone of technical means, could reproduce that. Since you have an 11/23+, you are in luck; that has one more 40-pin socket than the dual-width 11/23 CPU board. It can accommodate both the CIS MICROM option and the floating point MICROM option. On the dual-width 11/23 boards, you have to remove the floating point MICROM. You could remove the MMU chip to make room for the double-wide CIS chip carrier, but that'd be pointless because, if memory serves, the floating point registers reside within the MMU chip. The 11/24 has yet one more socket, so it has no such limitations. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
