3rd party HP-IB drives, Bering 7320SC Econopac (Ebay 180230181732)

by rdbrown＠pacific.net.au

Bering 7320SC Econopac Hard Drive Item number: 180230181732 The drive isn't mentioned in their current (2005) Econopac list. and a non-HP-IB paper tape reader/punch. GNT 4604 READER PUNCH CNC - TAPE READER WITH MANUAL. Item number: 120241325099 3rd party HP-IB => SCSI et al disk hardware - I wonder if any of them would consider releasing their code for the HP-IB emulation under an Open Source, Hobbyist or Non-compete license. I wonder too whether they have HP-IB device protocol manuals that could be scanned for bitsavers. Looks like Bering may do Amigo, SS-80, CS-80 http://www.bering.com/home.htm (web page not recently updated, still in ylwbook.addresses.com phone book) Bering Technology, Inc. 1400 Dell Ave., Ste. B Campbell, CA 95008-6620 USA I think these guys are selling SS-80 9122 etc devices http://www.isa-j.co.jp/english/product/HP/HPIB_SCSI/ CS-80 drives targeting HP-1000 & HP-3000 systems (still in online phone book) http://www.reactivedata.com/2-LegacyDiskAndTapeEmulators/leghp1000.htm

Research Unix v9, v10

by slawmaster＠gmail.com

I've been thinking about some of the later versions of Research Unix, such as v9 and v10. If I could track down install tapes/disks, would I be able to run it on my VAXstation 4000-60? It seems that post-v7 didn't spread very far, so I guess I won't be too surprised if nobody knows :( John -- Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn

Suns available in Germany

by Arno_1983＠gmx.de

Hello fellow collectors, University is about to clean out storage space and there are a few older Sun workstations which will probably get their tickets: 4x SPARCstation 10 2x SPARCstation 20 5x Ultra 5 (both sBus and UPA versions) 2x Ultra 10 (or so) I did peek inside and didn't find anything particularly exciting (e.g. matched processors or unusual boards) so I suppose they will not warrant shipping and would have to be picked up at Erlangen University, southern Germany. Some do have memory and disks installed, others were robbed. So long, Arno -- Arno Kletzander Student Assistant // Studentische Hilfskraft Informatik Sammlung Erlangen www.iser.uni-erlangen.de Psst!

Apple ADB mouse optical conversion

Does anyone here have any ideas on how one would go about converting a ball-type Apple ADB mouse into an optical one? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.

Dilog DQ132 question

by tiggerlasv＠aim.com

I guess my first question would be - If you're running on an 11/83 under RSTS/E, why WOULDN'T you want to use 22-bit addressing? Surely you're not "wasting" a perfectly good 11/83 on V6C or V7.0 ? ;-) But, to answer your question - My interpretation is that you can: Use 22-bit addressing, in which case RSTS/E (V8.0 and above) will see the controller as a TSV05, and will use 22-bit addressing to access memory above 256K (when applicable). You'll note that if you do a HAR LIST under RSTS/E V8.0 or above, it will flag this drive as "extended features enabled", indicating that it can use the full 22-bit address range. or Set 18-bit addressing, in which case RSTS/E (V7.0) will see the controller as a TS11, which will ONLY be able to access 256K of memory without modification to the device driver. (V8.0 and above might (properly) recognize it as a TSV05 either way, however, the "extended features" will be disabled, and it will only be able to access 256K of memory.) If I left anything out, I'm sure someone will chime in. . . . Tim

Ignore all those puny Unibus and Q-bus machines without MMU, will you? But they still run RT-11 just fine! Guilty as charged on the 11M+ part. :-) However, I think I covered machines without MMUs as well, I just didn't spell it out. Without MMUs are the same as machines with the MMU disabled. The one thing that differs is who puts out the extra bits on the address bus if there are more than 16 address bits, when you don't have an MMU. The CPU do, in those machines. Oh well. And I thought I'd done a real proper job. :-) Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

LA180 doc finally all scanned

by mouse＠Rodents.Montreal.QC.CA

Some time ago (two months? I forget) someone sent me the "LA180 DECprinter I Maintenance Manual" to scan. Thanks to the good offices of our very own Dave Dunfield, the 8?x11 pages were easy. I finally went through the foldout pages, scanning them with my flatbed. What I have not done: (1) where two scans were necessary to cover a whole page (which was true of most of the foldout pages), I have not merged the two scans into a single image file; (2) I have not interfiled them into the PDF, largely because I've never bothered to create/find PDF building/busting tools (the only PDF-aware software I have at hand is ghostscript). However, the information is all there. See ftp.rodents.montreal.qc.ca:/mouse/docs/DEC/LA180/ - the .pdf is the 8?x11 scans; the scan.%03d.bz2 files are the scans of the foldout pages. I think the pages are in order - that is, if page N is before page M, all scans of page N have lower numbers than any scan of page M. Anyone who cares to is welcome to pick them up and put them somewhere more appropriate, like bitsavers - I suspect anyone doing that would want to do the things I mentioned above I didn't do, but, well, that calls for a Princess Bride quote.[%] Most of my scans were 300dpi 1bpp line-art scans. Two pages came out quite horrible when done that way; those I scanned as greyscale - you can identify them by the file sizes (scan numbers 003/004 and 022/023, as it happens). Some small number of my scans (two, I think) actually fit on an 8?x11 page, just sideways. Those scans have been rotated so they're right-ways-up when the image file is viewed the usual way. My scans are bzip2ed PBM (for the 1bpp) or PGM (for the greyscale) files. If someone needs something else, like TIFF or GIF, let me know and I'll see what I can do. Unfortunately the FTP daemon I'm running, while it supports conversion on request, does not grok *removing* suffixes to generate requested files. If you need bunzip2ed versions for some reason, let me know and I'll see what I can do. I still have the dead-tree version, so if you find anything that needs rescanning or any such, it's not out of the question.

Dilog DQ132 question

by mcguire＠neurotica.com

Hey folks. I'm trying to get an Overland Data OD3610 drive working with a Dilog DQ132 controller in a PDP-11/83 running RSTS/E. The DQ132 manual documents dipswitch S8 as enabling 22-bit addressing, and it defaults to disabled. Here's the relevant paragraph from the manual: ------------- Switch S8 selects between 18- and 22-bit addressing. Only the TSV05 software handler supports 22-bit addressing on the Q Bus. The TS11/TU80 handler may require modifications to support 22-bit addressing on the Q Bus. Default value is S8 ON, selecting 18-bit main memory addressing. ------------- So am I to assume that it can be used as a TS11 in a 22-bit system, and the driver uses bounce buffers? Any idea? Thanks, -Dave -- Dave McGuire Port Charlotte, FL

Looking for a M8330 or a couple of SN74194's

by RodSmallwood＠mail.ediconsulting.co.uk

Hi Its not test gear that's the problem its access to the board. My Tek 465 will trigger on single pulses with no problem. However whilst it's recommended that the the first CPU board (the 8330) be in slot 2 (The front panel is in No1) its not mandatory. So I can move the boards back a bit and get to the front of the 8330. Manual I have, (very good) Schematics also (Awful) so bad I may even redraw at least the 8330. I have an A0 HP plotter so its easy to do drawings.

I don;t know what test gear you have, but I find a simple logic probe to be more use than a 'scope for this sort of problem. The former can easily detect narrow pulses that are difficult, if not impossible, to see on a non-storage 'scope. Of course an 'Advanded Logic Probe' as HP called the LogicDart is even nicer, but... Do you have the maintenance manual? Not the printset (schematics), but the book which is a low-level circuit description? It's well worth reading!. I would have thought it wouldn't be too hard to keep on hitting the DEP key and seeing what, if any Omnius signals are generated. And then totrace back the missing one(s).

Ticking SMPSUs are often quite simple to fix, maybe just dried-up capacitors. -tony
