Which Dec Emulation is the MOST useful and Versatile?

by computerdoc＠sc.rr.com

Hi DEC Enthusiast's, If I were to have to decide on just one model DEC PDP system to run in a DEC Emulator, which one would be the most useful, versatile and has the most software available for it? I have only ever used a real PDP-8/e system way back in high school so I'm not up to par on any other model of DEC PDP system and I only know BASIC on the PDP-8/e so not much there either. I hear a lot about the PDP-11. I found out that there were 16 major PDP models at one time so I'm not too sure which one to pick. I built Oscar Vermeulen's PiDP-8/I which I'm waiting on 1 part for. Other than that project which is in a holding pattern at the moment, I have no other PDP anything running in any form. Back in the day when Bill Gates and company 1st started out, I had always wondered how they developed their very 1st software program - Altair Basic. I was pleasantly surprised one day when I saw a B/W photo of a young Bill Gates bending over the operator at what looked like a very small computer. Maybe it was just a terminal. I don't remember. I understand they did software development on a DEC PDP of some sort. Finding this out regenerated my interest in the DEC PDP line of computers. I have many projects in the works already so I decided to setup a software emulation of just one of the DEC PDP models. I have heard a lot about the PDP-11 which if the information I read is correct was 16-bits. My PiDP-8/I is 12 bits. I understand the PDP 10 was 36-bits and the PDP-15 was 18-bit. The PDP-11 is the model I hear the most about. I also have some experience on some version of a VAX when I was in the Air Force so I'm thinking of getting a VAX emulation going at some point too. So if I'm going to do this, what suggestions, pointers, experiences, etcetera do you guys have for me. I am very interested in the DEC PDP equipment though next to no experience so I have no basis to make a decision. This is a serious request so I would definitely like to hear what you all have to say. If you have read this far, thank you. Take care my friends.

It appears to do nothing but create more problems if turned up higher than that. It was worth a try. --Chuck

Cloning A Hard Disk Over The Network Using Ultrix

by robert.jarratt＠ntlworld.com

I have a couple of hard disks I want to make dd copies of. I have Ultrix running on my DECstation 5000/240 with the disk I want to clone attached to it. The trouble is that I don't have enough disk space on the machine to clone the disk and then grab the image using FTP. I have been trying to find a way to pipe the dd output over the network to a SIMH Ultrix machine that has plenty of disk space. I tried piping dd into rcp, but rcp doesn't seem to take input from standard input. I have looked at cpio, but that too appears not to accept input from standard input. Unix is not my strong point. Are there any other ways I could pipe the dd output across the network to a machine that has enough disk space? Thanks Rob

CDP1801

I'm going to put it on my list of projects to create a CPU card for my Microtutor that uses the 1802 instead I think.? I can get some blue PCB stock.?

DEC Emulation Website

When I > started them, one of the design goals was that they be readable with > Lynx. I?m not sure how important that is anymore. :-) I have browsed it just few moments ago with lynx, emacs-w3 and my new textual favourite, elinks (it multitabs!! and shows tables!! and I could play with configuration a lot, so on 256-colors-enabled term it looks a bit nicer to my eyes). In all them, and in some old graphical one, the site looks decently. As of "modernisation"... You know, just MHO and stuff but sometimes when I see modern pages it seems like their creators have had been abducted to some sect and brainwashed clean. I have 1600x1200 and I like to have some other window besides browser (say, an editor, like emacs). So I open such page, and the browser has about 3/5 of estate and I am not going fullscreen, no way. And there is huge menu on the left side, so I can choose. And there is some (expletive0) "top bar", all white and empty, or maybe with page title (I already have one (expletive0) title on a title bar of browser window), then there is (expletive0) bottom bar, all empty. And for a text, there is area left which is about five to ten (expletive0) lines high. There is no (expletive0) way to make those (expletive0) elements go the (subseq (expletive0) 0 4) away. The last resort is to turn styles off, which quite often gives me almost the view that I would like to have, plus (quite often) a parade of (expletive0) leftovers from the leftside menu, which after switch takes more than 90% of (expletive0) web page. I swear I do not make this up. The usable part of the modern webpage is on average the (expletive0) ten percent, as measured by scrollbar - and sometimes even less. The only reason I keep using very old Opera 1x.x is because it: A) does not multithread (so when I load heavily crapped page, it only (subseq (expletive0) 0 4)s with one core of my cpu max, rather then (expletive0) with me fulltime B) is able to show very decently a page with styles turned off; this also sometimes means lowering core usage by half (the usage which is there even when (expletive0) browser is expected to sit on its (expletive1) and do nothing). C) I turned a lot of CSS off by default, but I am not quite sure if this really works (software, trust, does not compute) - and I put fixed/monotype fonts wherever I can see them, because I love the idea that space is same width as "i" and "W". So all the job done to max my pleasure with downloadable fonts is lost, and (expletive0) good for me. I have tried switching to Firefox, but somehow having eighty tabs does not work very nicely there, for me at least. But I launch it when there is something that poor Op cannot render properly. Overally, I have few browsers opened as day goes by, one for Common Lisp docs, another for casual reading, one for sci articles heavy with equations and gfx (mostly up-to date rendering 'gine), few text browsers for interesting stuff, books or longer reads etc. I have recently started to experiment with Dillo - this is very nice piece of (expletive2), recommended to everybody even if it not always shows things, kind of like text browser with graphics (sometimes) and multitabs. Perhaps will also try "old new" Mosaic - the old one got lost during innumerable system upgrades. As I could have observed, plenty of people out there think that "modern" means "optimised for mobile", but what does it mean in practise? The text, i.e. useful part of the page might take 10 kilobytes (optimist, me, always), there might be even useful pictures on it, and then there goes a (expletive2)load of javascript. Megabyte is a, kind of, norm. So, this (expletive2) eats my download/upload quota, for which I pay (in theory, because I never was in such position). And then it starts running and eats from my battery, which can be loaded for peanuts, but who wants to recharge every few hours - this is supposed to give me mobility, but not to/from wallsocket. Which is how I came to brainwashing - the words being used are redefined. Optimised no longer means what it used to mean. Now it just means conformance to some group's standard. Optimised for pats in a back, just not from enduser (some endusers dream of packing boot deep into webdevel's (expletive1) and leaving it there, and the second boot would go to their halfbrained tasteless boss'es (expletive1), only deeper). For me, "optimised for mobile" is something like HTML1.0, or maybe even 3.0 (if this is when tables were defined). And "modern" is unimportant, if a goal is information retrieval. If you (or anybody) plan to upgrade your webpage, please consider doing it like XIX century guy, just barely after computer lessons. Text is everything. Because this is how information is being transmitted. Pictures are few, and if they are there, there must be a purpose (like, they too convey some information somehow related to text). So this is my opinion on modern web design, and mind you, I am not using it on a cell phone, but on something as big as two A4 pages, and the (expletive0) web cannot do very well on such (expletive0) huge area, or significant part of it. What are "they" using for making their creations - a monitor wall? I cannot imagine my state of mind if I started to depend on a cellphone for web reading, but I guess a dictionary of expletives could get few new words. There is no day without cursing the web here, despite all the heavy measures I took to protect myself from poor (i.e. modern) design. Well, maybe I curse the web only every other day, plus every time the page almost loads except one small element (perhaps some JS dependence, and server is down/restarting so I wait minutes because reloading only makes things worse in this case - but perhaps this is my ISP's fault, but then ISP is part of it, too). As of Javascript - sure there is a place for it. I dream of writing a compiler in Javascript. A few have been written. Ok, maybe I do not dream so much to learn Javascript. But the whole "page is an app" is just misunderstanding in best case, or more probably, some kind of crime - crime against reason, for example. This was meant to be short(er), but got long(er). Blame the web. -- Regards, Tomasz Rola -- ** A C programmer asked whether computer had Buddha's nature. ** ** As the answer, master did "rm -rif" on the programmer's home ** ** directory.

C64 to a good home

by drlegendre＠gmail.com

Hey Kevin. This is all good advice, but there is also another way to go - and it's a bit more future-proof. For about the same cost as the Zoom floppy, you can get a device called an SD2IEC or similar. It's very simple - it connects to the IEC (disk drive) port on the C-64 and accepts a micro or mini SD card. This way you only need copy your C-64 titles to SD card (any way you like) and they will be accessible to the C-64. The device behaves like a 1541 / 1571 drive. I say the SD2IEC is future proof, as it doesn't rely on original 15X1 disk drives or 5-1/2" media, all of which could go away someday. Now _personally_ I use a home-built XM1541 cable with opencbm (free/OSS) to transfer my images to genuine 5-1.4" disk. I only do this as I'm too cheap / broke to buy something else like the SD2IEC. It is exceptionally stable and reliable - once set up, it "just works". Though if you a) run Linux and b) accept a kernel update you will need to c) recompile & re-install opencbm as the module is built specific to the running kernel. This takes only seconds, literally. -Bill On Mon, Oct 16, 2017 at 7:48 AM, Robert via cctalk <cctalk at classiccmp.org> wrote: > I recently bought a ZoomFloppy from here: http://store.go4retro.com/ > zoomfloppy/ > > I got the version with an IEEE488 conector, for use with a PET, but it > also supports the serial interface used on the C64. > > On Sun, Oct 15, 2017 at 9:11 PM, Cameron Kaiser via cctalk > <cctalk at classiccmp.org> wrote: > >> There are some online repositories of C64 software.

I was looking at an old GI catalog and casually noting the CP1610 that was most of a PDP11 processor. I did some more web surfing and noticed that the Intellivision game machine used this chip. It just never dawned on me that they used this processor. I see that one could even get a keyboard for these. Dwight

Spring cleaning time! I have three vintage HP 9836 computers, two monochrome monitors, one color monitor and three printers. I'm sure they are going to need work to get running. No testing has been done. Could probably get two out of the three working. Somewhere I have a few various I/O cards also that will be included. Photos can be seen here: http://anifur.com/clist/ Pickup in Santa Cruz, CA, I just don't have time to (or the back) to pack and ship, though I can help load. -Bob -- Vintage computers and electronics www.dvq.com www.tekmuseum.com www.decmuseum.org

Corona Data Systems PC available

I have a couple of the Corona and Cordata desktops. Apparently Corona Data Systems was forced to change their name when the manufacturer of Corona typewriters objected.

Firefly dual processor card

by spacewar＠gmail.com

Did you get an actual Firefly (research) board, or a prduction VAXstation 3520/3540 board? I don't think you're likely to find schematics or pinouts for either, but it's not impossible to find 3520/3540 stuff, while I've never before heard of anyone encountering any actual Firefly boards in the wild.

Anyone remember ZOSO disks?

by asc135＠gmail.com

Back in the 80's I had some archive disks (maybe SIG/M or CPM/UG or maybe something else?) which had files on the disk named like ZOSO.022 (for disk #22) which was the Star Trek basic game disk. I'm attaching below the text >from that file (best viewed with a monospace font). I seem to recall this person who went by the moniker of Zoso had written others as well, but I can't find them right now. Just curious if any of you had seen those and if anyone knows who this mysterious Zoso person was? If I find others I'll post them. Regards, Amardeep AC9MF * * * * * THIS DISK CONTAINS THE FOLLOWING FILES: STARTREK.TXT THIS IS THE ORIGINAL SOURCE FILE FROM WHICH THIS PACKAGE WAS DEVELOPED. IT IS PURPORTED TO RUN AS IS WITH MITS 8K BASIC. IT CONTAINS ALL THE REMARKS, AUTHOR CREDITS ETC. IF YOU HAVE THIS BASIC WITH ASCII-LOAD CAPABILITY, TRY IT !! BIGTREK.ASC THIS IS THE RESULT OF HAVING TRIED TO TRIM THE ABOVE SOURCE SO AS TO GET IT TO RUN (IN A 64K SYSTEM) WITH MICROSOFT'S MBASIC. IT PRESENTLY IS ALMOST SHORT ENOUGH, BUT NOT QUITE. BECAUSE OF THIS, THE OBJECTIVE BECAME TO MAKE IT SUITABLE FOR TDL'S DISK BASIC RUNNING IN 64K. IT RUNS QUITE NICELY THAT WAY. ALL OF THE FEATURES OF THE ABOVE PROGRAM ARE RETAINED, AND A COUPLE OF NEW ONES HAVE BEEN IMPLEMENTED. BIGTREK.BAS THIS IS THE COMPACTED MACHINE CODE OF THE ABOVE FILE WHICH LOADS ABOUT 50 TIMES FASTER THAN THE ASCII VERSION (TDL DISK BASIC ONLY). THE PROPER STEPS TO LOAD THIS ARE AS FOLLOWS : (ASSUME YOU HAVE LOADED TDL BASIC INTO A 64K SYSTEM)... 1 - OPEN#1,"I","BIGTREK.BAS" <CR> 2 - LOAD "B" <CR> 3 - CLOSE#1,"I" <CR> 4 - RUN <CR> TREKINFO.DOC A BRIEF TUTORIAL ON THE RULES FOR PLAYING THIS, CROSS-REFER- ENCED WHERE POSSIBLE WITH THE FAMILIAR COMMANDS OF THE MORE COMMONLY AVAILABLE 'STARTREKS'. TREKMOD.ASC SEE EXPLANATION (IN POST-SCRIPT). STRTRK/2.ASC THIS IS INCLUDED BECAUSE I LIKE THE 'COMMUNICATIONS' AND 'MIS- SION-PROGRESS-REPORTS' THAT HAVE BEEN IMPLEMENTED IN THIS MUCH SMALLER (STILL > 20K) VERSION. NO MATTER HOW YOU GO WITH THIS, IT IS LIKELY THAT YOU WILL NEED 64K (PERHAPS 60K IF YOU USE 8K BASIC) TO RUN IT AT ALL. ONLY GUARANTEE IS THAT IT WILL RUN WITH TDL DISK BASIC/64K AS IS. SINCE I CAN RUN THIS, I LEAVE IT TO SOMEONE ELSE TO GET IT WORKING WITH EITHER MICROSOFT DISK BASIC (OR BASIC-E). ONE SUGGESTION FOR THE FORMER PROJECT MIGHT BE TO PARTITION THIS PROGRAM INTO TWO MODULES. THE FIRST WOULD CONTAIN ALL OF THE LINES RELATING TO GALAXY INITIALIZATION, DIMENSIONING STATEMENTS, DATA- TABLES AND ALL BEGINNING OF GAME DIALOGUE - IN OTHER WORDS, LINES NOT REFER- ENCED AFTER GAME IS IN PROGRESS. THIS FILE MIGHT BE CALLED 'STARMOD1.ASC'. THE OTHER MODULE, 'STARMOD2.ASC' WOULD CONTAIN EVERYTHING ELSE. THE LAST COMMAND (TO BASIC) IN 'STARMOD1.ASC' WOULD BE: MERGE"STARMOD2.ASC". BOTH MODULES WOULD HAVE TO BE RENUMBERED IN SUCH A WAY THAT AT THE BEGINNING OF THE 'MERGE', EACH NEW LINE OF 'STARMOD2' WOULD WIPE OUT A LINE OF 'STARMOD1' WHICH HAD THE SAME LINE NUMBER (UNTIL EVERY LINE OF FIRST MODULE WAS OVERWRITTEN BY A NEW LINE >FROM SECOND MODULE). ONE CHANGE WOULD BE NECESSITATED IN THE SECOND MODULE: IF A PLAYER REPLIED 'Y' TO THE QUESTION, 'ANOTHER GAME ?' A BRANCH WOULD NEED TO BE MADE TO A LINE WITH THE FOLLOWING COMMAND, - RUN "STARMOD1.ASC". THIS SOL- UTION IS A BIT 'KLUGEY', BUT PERHAPS PREFERABLE TO FURTHER TRIMMING. SEE THE 'P.S.' BELOW; THE MICROSOFT MANUAL IMPLYS (BY NO PROHIBITION) THE LIKELIHOOD OF SUCH (ABOVE-MENTIONED) ARTIFICES BEING EFFECTIVE. THE DISAPPOINTMENT THAT MR. DOGGE ENCOUNTERED SHOULD BE ATTRIBUTED TO HONEST EXPERIMENTATION COMBINED WITH (THE TYPICALLY) INADEQUATE DOCUMENTATION. HAVE FUN !!! - ZOSO LATE NOTE: THE EXPERIMENT WITH MERGING TWO OR MORE MODULES HAS BEEN TRIED. I AM SAD TO REPORT THAT THIS APPROACH APPARENTLY DOES NOT WORK. IT SEEMS THAT THE EFFECT OF THE 'MERGE' FUNCTION IS TO DESTROY DATA (IN ADDITION TO CERTAIN LINE NUMBERS). MY THANKS TO MR. E. DOGGE FOR THIS INFO. E.D. ALSO SENT A 'TRIM- JOB' OF 'BIGTREK' CALLED 'TREKMOD'; IT PLAYS THE SAME GAME, BUT LACKS THE 'SCO- RING' AND 'VISUAL' FUNCTIONS. NOT TO DEMEAN MR. DOGGE'S EFFORT, I CAN'T PER- SONALLY SEE HOW THIS PARTICULAR 'STARTREK' CAN BE MEANINGFUL WITHOUT THE SCO- RING ROUTINE. IF THIS WERE MY 'BABY', I WOULD (IF NECESSARY) REDUCE EVERY BIT OF (TEXTUAL) CONSOLE OUTPUT TO A 2 DIGIT CODE SO AS TO RETAIN 'SCORING'; THE 'VISUALS' ARE CUTE BUT NON-ESSENTIAL. SEE WHAT YOU THINK. ALSO !!! THERE ARE (IN THE 'BIGTREK' FILES ONLY) SOME CRUCIAL ERROR TRAPS WHICH I INSERTED. LOOK FOR THESE AT THE BEGINNING OF THE 'NAVIGATE' AND 'IMPULSE' SUBROUTINES. THE COMMON STARTREK PRACTISE OF INPUTTING A '0' WARP-FACTOR (DISTANCE) TO ABORT AN IMPROPERLY ENTERED NAVIGATION ROUTINE WILL, WITHOUT THESE TRAPS, GIVE YOU A 'SUBSCRIPT OUT OF BOUNDS' ERROR, AND THE GAME WILL HAVE BEEN (LITERALLY) LOST. I SUGGEST COPYING THESE EXACTLY IF YOU WILL BE TRYING THE 'TREKMOD' IM- PLEMENTATION.

The Mysterious Zoso

by tshoppa＠wmata.com

Al struck a memory cell I haven't used in at least a quarter century. No, I do not know who The Mysterious Zoso actually was but he was legendary. His flaming just barely crosses the line into early trench industry journalism I guess. Certainly not the shine of Charlie Matco or Ted Dziuba, but maybe the first step in that direction? >From CPMUG 21: BITCH, BITCH, BITCH !!! SOME PEOPLE ARE JUST INCAPABLE OF BEING CONTENT. NO SOONER THAN I HAD FINISHED MY REPLY TO ALL OF THE TTY PEOPLE (VOLUME 13.21), TONY INFORMED ME THAT SOME VDM OWNERS HAD TROUBLE READING MY 80 CHARACTER LINES ON THEIR QUAINT I/O DEVICES. I WILL NOT ACCOMODATE YOU, AND HERE'S WHY: I PAID GOOD BUCKS FOR THE TOOLS I USE, AND I CHOOSE TO USE THEM. FRANKLY, I CAN'T FATHOM WHY ANYONE WOULD ADMIT TO OWNING ONE OF THOSE THINGS AT ALL. I'VE SEEN WHAT YOU GUYS ARE UP TO: THOSE HORRID, NARROW LITTLE PROGRAMS WRITTEN IN PROCESSOR TECHNOLOGY'S 5K BASIC (YOU KNOW THE ONES WITH A LINE FOR EVERY SINGLE LITTLE THING - 15 DECWRITER PAGES JUST TO PRINT YOUR VERSION OF WUMPUS [ABOUT WHICH I SHALL BE HEARD FROM LATER]). YOU GUYS HAVE EXPOSED YOURSELVES TO CAT- ARACTS AND MYOPIA BY LOOKING AT YOUR VDM'ED TVS. LEAVE ME OUT OF IT !!! THE COMPANY WHO SUPPLIED THOSE B & W CRAYON BOXES TO YOU IS A PLACE TO SUSPECT...

FTGH clear-out at Mesa Electronics, Richmond, CA, USA

by jnc＠mercury.lcs.mit.edu

> From: Paul Koning > For some definition of "standard". ... other machines of that time or earlier > numbered bits according to the power of 2 they represent, i.e., the "current > standard". Well, the vast majority of computers 'back then' numbered bits (and byes) >from left to right - which is why in numbers in TCP and IP, the bytes go from left to right (necessitating byte swaps on most current architectures before sending a packet out into the network). The majority of computers being attached to the network when TCP/IP was being defined used that byte order (I think PDP-11's were the only exception, but I'm too lazy to check a copy of HOSTS.TXT to make sure), and so that's what we're stuck with now. So, I can see, centuries in the future, the bytes in a word on the Internet (and it _is_ capitalized) still being in an order set by long-dead computers. Kind of like how rail gauge today still mimics the width of Roman carts (yes, I know the story is only half-true, but it's not wholly wrong). Noel

Firefly dual processor card

by mark.kahrs＠gmail.com

Against my better judgement, I obtained a DEC SRC Firefly dual processor card. If i read this* correctly, then this card is interfaced to the shared memory bus (MBUS) as opposed to the QBUS (the card uses a Q bus format). I realize it's probably hopeless, but I'll ask anyway: Are there any schematics or specifications on the connectors anywhere? *IEEE Computer, also available on Bitsavers as a technical report.

The ribbon loop is maybe 18 inches? I have a new in bag ribbon which I am sure is also dried out. I used a drop of thin oil on the reinking roller the last time I messed with it and that seemed to work. You probably want to use something that will lubricate because the pins on the dot matrix print heads do need that to keep them >from rusting and wearing out. The "stutter" you mention is normal. The printer electronics buffers a few characters during the slow carriage return and prints slightly faster than 30cps so when a new line is started it goes at full speed until the buffer is empty at which point it goes into the stutter mode. This eliminated the need to send nulls after a carriage return that was necessary on the earlier purely mechanical printers. -- Doug Ingraham PDP-8 SN 1175

DEC rack-mount AlphaServer 2100A

by pbirkel＠gmail.com

If there's anyone out there with a rack-mount DEC AlphaServer 2100A - the one with the underslung pair of power supplies -- I'd appreciate your help in determining the 15-pin control-cable configuration for J3. It may require examining the other end of the "power supply control cable assembly" P#17-04014-01, which is 24-pin (to handle the dual/redundant power supply configuration). Available hardware documentation is pretty sparse. Physical examination of an AlphaServer 2100A system backplane (54-24129-01) would certainly help! While I'm pretty sure that I've figured out the +5V +- sense lines (pins 3-4), and the +3.3V +- sense lines (pins 15-14), I've failed to determine the purpose of other control lines - most particularly which one(s) turn it on. Pins 10 is suspect, but there's no obvious reference point for voltage measurement or evidence whether it should be shorted to another pin, or . something else. There's no control relay or other obvious mechanism. The PCB is dense-packed with surface-mount components on one side and power components on the other; tracing circuits is a bear. Applying AC starts up the 24VDC fans, but none of the four switchers kick in :-<. Thanks for any clues! paul

HP9816 keyboard plunger wanted.

by mattislind＠gmail.com

Hello! I recently received a HP9816 machine. The previous owner originally got the machine without a keyboard but subsequently sourced a keyboard off ebay. Unfortunately this keyboard was not in the best shape. One key was stuck and when taking it apart it was evident that it has taken a bath for quite some time. At least the electronics around the space bar were quite affected with corrosion. Luckily this keyboard is quite simple design with only CMOS 4XXX IC, and better yet, Tony Duell has already reverse engineered it (together with the rest of this little machine). Thanks a lot Tony! But the stuck key appeared to be cause by the "plunger" (is that the correct english word?) is slightly cracked in the corner. When the keytop is inserted it is not sliding very well. I have not found a method of repairing it so I am asking the community if there are anyone that has spare "plungers" for the HP9816 keyboard. http://i.imgur.com/q5aRQnC.jpg?1 http://i.imgur.com/67xWZ8q.jpg?1 http://i.imgur.com/cGWCKFw.jpg?1 This is the keyboard at the hpmuseum.net page: http://www.hpmuseum.net/images/200serieskeyboardsmall-35.jpg /Mattis

Random musing: VCB02 on VAX-11/750

by derschjo＠gmail.com

So I had a random thought in the wee hours this morning and I leave it to you, the cctalk braintrust, to tell me exactly how stupid this idea is: I have a VAX-11/750, an Able QNiverter (UNIBUS->Qbus adapter), a 22-bit Qbus backplane, and a VCB02 (QDSS) 4-bit graphics boardset. Theory: With an appropriately modified NetBSD driver for the VCB02, such that it provides only 18-bit addresses to the VCB02's DMA engine, I can get X running on the VCB02 on the 11/750. That is, the configuration is: 11/750->Unibus->QNiverter->Qbus->VCB02. Obviously the console functionality of the VCB02 won't work since that requires support on the VAX side of things that won't be present, but I think everything else should work. I've browsed the technical manual and I don't see anything that should get in the way, I'll just need to hack up the driver appropriately. But this is something that randomly popped into my head (I was inspired by a research paper, "A VAX Based Data Acquisition Computer System at the Nuclear Structure Research Laboratory" wherein a Matrox QRGB Qbus graphics board was lashed to an 11/750 in a similar manner... What say you all? - Josh
