Greetings, I'm in possession of a reasonably complete set of SVR3 media (and associated drivers, diagnostics, etc.) for the AT&T 3B2 on 5.25" QD floppies. Sadly, I no longer have any 3B2 hardware, but with luck one day I may change that. I had planned on imaging and preserving these disks for my own use, if nothing else. But it occurs to me that I don't know how rare they might be, and I might do harm by attempting to read them in an EBay'ed PC floppy drive (albeit with cleaned heads). Is this material sufficiently preserved that I don't need to worry about damaging my copies? I didn't see any 3B2 related bits on bitsavers and a cursory google search didn't turn up much. I have a few disks with duplicate contents, so I risked a test run with Unix dd and got a sane-looking complete image with no I/O errors, and no material shedding off the floppy that I could see. I still need to see if the bits are good at a higher level (I think they are formatted as "S5" filesystems, not sure). But I'd have no problem shipping the floppies to a respected member of the community who does this kind of thing all the time (e.g. bitsavers), if it would be worth their time. thanks, -Andy

Altos 586 physical diskettes or QIC Tape.

by spedraja＠ono.com

This is message that I send from time to time. I got one operative Altos 586. It has the Xenix Kernel damaged, and I don't have diskettes to start the system from them. If someone can do a physical copy of the set of disks available (I don't remember the exact place now) and send it to me, or even a tape to start the system (I'm not sure if this can de done), we can speak about a trade. Contact off list, please. Thanks Sergio

P/390E 1GB & ESCIMO

by BHuntsman＠mail2.cu-portland.edu

Hi all! Since it'd been talked about before, I thought I'd share some photos, in case anyone ever wanted to see what this stuff looks like! Here are some pictures of my prototype P/390E board with 1GB of S/390 memory: http://www.flickr.com/photos/87479714 at N05/sets/72157631592809957/ And, after years of searching, and quite a bit of help, I managed to land an "ESCIMO" ESCON channel board from an IBM 3006 S/390 Integrated Server. Just got this in the mail today! It will work with the P/390E board, though I'll probably have to remove the blue extension at the end to get it to fit into my PC Server 330. Here are some pictures of it: http://www.flickr.com/photos/87479714 at N05/sets/72157631592838663/ -Ben

However, under the heading "How to connect a Sony Multiscan monitor to a VS3100", it suggests connecting pin 9 on the VAX (monochrome signal) to pin 6 on the monitor (red return). The monitor may well have all the returns connected together so the display may work fine and the incorrect connection may not be noticed but damage could be done to whatever is driving the monochrome signal on the VAXstation system board. Regards, Peter Coghlan.

PromICE 'loadice' software

by snhirsch＠gmail.com

Does anyone have support software for the Grammar Engine PromICE ROM emulator? There were utilities built for Mac, Sun SPARC and MS-DOS (I'm primarily interested in the last). Mine seems to be what's discussed in the V3.0 manual on bitsavers. If bitsavers has the diskette images, I couldn't find them. Steve --

RGB ground 10. Green 11. Blue There is also a monochrome video signal available from the frame buffer on the system board which is not usually used if you have one of the optional colour graphics cards: 3. Monochrome ground 9. Monochrome video If you make up an DA-15M - DA-15F adapter to get at these, you can probably run your VS3100 double headed. I've done it with a GPX graphics card and VMS. I assume it is also possible with an SPX graphics card. I can't see why not.

Wanted : Dunp of HP9820 Peripheral Control II module

by ard＠p850ug1.demon.co.uk

Does anyone have a dump (in any sane format [1]) of the Peripheral Control II (PC-2, whatever) ROM module for the HP9820 calculator? Not PC-1, which I already have. Last time I looked, it wasn't included with the HP9800e emulator. Also looking for dumps of the DataComm 2 and DataComm 3 moduels for the HP9830 (I have DataComm 1), but these are much less important at the momnet. [1] Plain binary, Intel Hex, List of octal numbers (as used by HP9800e), BPNF, Motorola S record, whatever. Thanks in advance ofr any help -tony

It has a DA15M which carries RGB signals with sync on green. I have a DEC cable called a BC19S which converts >from the DA15 to three BNC connectors which plug into my monitor. The keyboard and mouse signals are also carried on the DA15 on some models but this doesn't seem to be the case with the M76. My keyboard and mouse are plugged in to the back of the VAXstation. There are no horizontal and vertical sync signals on the DA15 connector so conversion to VGA requires some sort of active device. The SPX card has two switches on it. One of them allows the resolution to be changed. One or other setting may be more suitable for whatever monitor you have available. Any sort of an LK201 or LK401 or similar keyboard as used on VT220 or VT420 or several other terminals seems to work fine with the 3100. There is a small recessed switch on the back of the VAXstation which allows a terminal plugged into an MMJ socket to be used as the console instead of using the graphics system as the console. Do not be tempted to plug in or out the DA15 cable while the power is on. I damaged my SPX card by doing that :-( Regards, Peter Coghlan.

Early Sun manual archives?

by derschjo＠gmail.com

Hey all -- (Here's hoping this makes it to the list, my last couple of mails appear to have disappeared into the nothing...) I was fortunate to come into possession of a very complete Sun-2/120 workstation last week. (Complete enough that it came in the original boxes and included amongst other things a bottle of tape head cleaner with a Sun P/N on it...) Included with the system are maybe 8 feet of manuals and other ephemera, I haven't done an extensive inventory but it seems to cover SunOS 1.0 through 3.0, some hardware documentation, and I have other assorted goodies like the first few issues of the Sun User Group "README" newsletter, sales pamphlets, sales invoices and correspondence between the buyer and Sun. I haven't found any digital archives of this stuff (but perhaps I've been looking in the wrong places). Is any of it of particular interest w.r.t. archiving? (Anyone with a bulk scanning setup willing to take it on?) - Josh

> >ON top for the reason of.. > >What flavor of 3100? It makes a difference. > Do you mean it makes a difference as to what signals appear on the DA-15? The 3100 Cameron was asking about the video signals on and the 3100 I have which does not seem to pass the keyboard and mouse signals to the DA-15 connector are both model 76's. The 3100 I ran double headed some years ago was probably a model 30 or model 40 I've still got it somewhere but I haven't run it for a while now. I can't remember whether it passes the keyboard and mouse signals to the DA-15. My VAXStation 2000's definately pass the keyboard and mouse signals to the DA-15 as there is nowhere else to get them :-) > >I ask as I have 8 of them and no more than two of any variant. >The VS3100 series was not a monolythic model but the generic designation >for a group of system. > I have a few Microvax 3100's but I don't think I have any other variations of VAXStation 3100.

Slashing the letter O (Was: Re: Service bureaus (Was: Tek

In my ham radio contacts from the early?'60s till rather recently, I often saw the slash?used to designate a zero; I noticed the same thing in engineering school in the late '60s and early '70s.? And, I have a Teletype Corporation teleprinter that has the slashed zero type pallet (ah, fond memories of loud noises and the smell of oil), although TTY Corp did make a non-slashed zero type pallet for the same type basket.? It was my understanding that, at least in this country, it was the zero that was slashed rather than the letter O.? Ah yes, more possibilities for confusion.

original Fortran source for Prolog

by spectre＠floodgap.com

There are references in the literature to a Fortran Prolog interpreter, apparently written by Alain Colmerauer himself with Phillippe Roussel. Actually finding this interpreter, despite copious references to it, has been considerably more difficult. There are also references to a Berkeley Prolog (not University of California) that is also in Fortran. Does anyone have a lead on, or possess, any of these small early interpreters? Yes, I know about the WAM, gcc prolog, etc. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Male Macintosh geeks are so predictable.
