Well, I have received an encouraging response to my inquiry into whether there is sufficient interest in PDPs to have a special newsgroup. In addition some DEC people are asking for this as evidence to their management to prove that DEC needs to get agressive again in the PDP market. Therefore I am asking that anyone who wishes to see a PDP newsgroup send me email stating that fact. While you are thinking about that, on the 24th Feb. we are having a meeting with some of DEC's upper management in both the PDP and realtime areas (for example the manager of all PDP software development). We want to ask sharp questions, raise serious issues and give praise where praise is due. Therefore please consider sending me your thoughts on the following questions and anything else that you would like to see asked. 1> Would a PDP Ada be of interest? Of what type - a run-time only Micropower Pascal type system, a layered product, a straight cross-compiler? 2> Would you like to see development tools for VAXELN ported to the Ultrix environment? 3> Should DEC resume its multiprocessor PDP project? We where told that the J-11 chip has 4 (?) pins that where implemented purposely for multiprocessing and that it would be relatively easy to put several J-11s on one board. RSX already has multiprocessing hooks built in (for M-Plus at least). Imagine a parallel F77 on the PDP!!!!! 4> DEC informed us that the KXJ-11 coprocessor board will be released in 4-6 months. This board will contain a J-11, 512 kb local memory, 128 kb shared memory, 2 serial ports configurable as asyn. or sync., one 20 bit parallel port and 3 counter-timers. The board has no bus master capability. What else do you the user want? We suggested a 4 channel 12-bit A/D. Remember that the I/O devices on the KXJ are local, involving no bus traffic and that the KXJ will need to go through the host CPU, either a MVII or a bus master PDP, to use off-board devices. How about 1 Mb as an option? What about software support? Currently RT-11 and RSX will be supported. Do we want any extensions, drivers, etc. to allow near multiprocessor operation? A CSR and interrupt lines to get the host's attension? 5> Is there interest in making a KXJ-11 clone that is a bus master? The board would be something like this: J-11 CPU with optional FPU 2 serial ports 1 parallel port 512 kb, 1Mb, 2 Mb memory options 4 channel 12-bit A/D 2 channel 12-bit D/A This would be a full stand-alone SBC. This a chance to funnel user wants back to Maynard, so please send me email with your thoughts. I will try to post a summation of DEC's responses but remember that some of the items may be covered by non-disclosure agreements. The PDP is alive and well, so let's keeping pushing DEC in the right direction! Remember that I need your responses no later then 23 Feb. AM to use them. rneitzel@udenva Richard Neitzel Rockwell International Computer Aided Manufacturing and Control Box 464 M/S T881A Golden, CO 80402 303-966-7203

In addition good! >some DEC people are asking for this as evidence to their management to prove >that DEC needs to get agressive again in the PDP market. Therefore I am asking Hummmm .... Which DEC people? If it's people in MSD, then their management knows that there is interest. The DECUS PDP-11 Working Group has been meeting with the top guns in MSD, *but* we (the PDP-11 Working Group) NEED YOUR SUPPORT! Please keep following your oun leads, but I ask that you also keep the members of the WG informed of the "good, the bad, and the ugly". What we need is information, case histories, war stories, etc. to make our case, and be listened to by MSD and the V.P.'s of DEC. Please include Ed Cetron (Chairman of the DECUS PDP-11 Working Group) in your mailings. His Internet address is: cetron@cs.utah.edu If you want to include me fine, I'll forward it to Ed. My address is a bit of a mess right, and I'm only reachable by UUCP at: ....!rutgers!sunybcs!oswego!beadel NYSERNet says that we should be back on the Internet by Monday evening 15-FEB-88. When we are back on line my address will be: beadel@oswego.oswego.edu >that anyone who wishes to see a PDP newsgroup send me email stating that fact. From my commentary above you can take that as a yes. I will be mailing you my YES vote. For other readers, look at the proceedures for forming a new newsgroup in news.admin (I think). Basically, someone has to anounce the desire to form a news group. (There {is | are} special newsgroup{s} that one should use plus it dosn't hurt to use existing groups that are closely related to the proposed group). The person *POSTING* the notice has to collect the mail vote for one month, tabulate it, and forward the results to the netnews "keepers-of-the-order" at one of the backbone sites. (Names and addresses listed in the article in news.admin). It takes 100 more "yes" votes than "no" votes to form a "main" group (eg. comp.sys.dec.pdp). However a "secondary" newsgroup can be formed with fewer numbers (eg. alt.sys.dec.pdp). SO MAIL IN YOUR BALLOT! > 1> Would a PDP Ada be of interest?

There are to be no more releases (or sales) of ULTRIX-11. > 3> Should DEC resume its multiprocessor PDP project? We where told that There are some people who would like to see it, but from what we've seen it's *very* unlikely for DEC to do it. There are some third parties that have "PDP-11 clusters", "PDP-11 coupled processors", etc either in production or in the planning (dreaming) stages. >the J-11 chip has 4 (?) pins that where implemented purposely for >multiprocessing and that it would be relatively easy to put several J-11s on >one board. RSX already has multiprocessing hooks built in (for M-Plus at least). By who? Or does this come along with the story of a semi-conductor maker who has redesigned the J-11 and has gotten a 40MHz clock on it. BTW. DEC denies this story. >Imagine a parallel F77 on the PDP!!!!! > Would be interesting! > 4> DEC informed us that the KXJ-11 coprocessor board will be released >in 4-6 months. This board will contain a J-11, 512 kb local memory, 128 kb Is this for "public consumption" or were you under a DEC "nondisclosure" aggreement when you were so informed? If under the latter and you are putting this on the net, you may well have spoiled your chances of getting any other future plans out of DEC. >shared memory, 2 serial ports configurable as asyn. or sync., one 20 bit >parallel port and 3 counter-timers. The board has no bus master capability. >What else do you the user want? We suggested a 4 channel 12-bit A/D. Remember If the board is as far along in it's production schedual as you suggest, then it is highly unlikely that you will see anything else added to it. Your input *may* influence the next (if there one, or even a first), but of course what you hear "should not be construed as a commitment by DIGITAL Equipment Corporation" for anything. {:-) > This a chance to funnel user wants back to Maynard, so please send >me email with your thoughts.
