I use a very nice commercial C compiler/dev environment for my PIC hacking, the PCW system from CCS.

Yes, it was only single-feed, through a slot in the front of the box. I mentioned it though because he didn't specify a specific type and figured he might be able to find one with a little checking. Afterall, there are still ships using the Harris mini's as far as I know. I've not heard that Snap-II had been totally phased out of use yet. Jeff

So, that > shouldn't be too big a hurdle. Maybe, maybe not. Remember that the terminal I/O device can only do one thing at a time. If you've done a write to send the poll request, you don't have a read pending and it will take you a little while to start the read. If your OPTO22 widget starts sending its response before you get that read up then you will lose some or all of the response. It is possible to get the 3000 to indicate when it's got the read up by sending a read trigger character. The typical read trigger character is DC1 (control-Q) on terminal types 9 and 10 (among others), but this is changeable somewhat if you fuss around with the workstation configurator (TTUTIL.PUB.SYS?) and make up a new terminal type definition file which you then associate with a terminal device through SYSDUMP. The intended use of the read trigger character is telling the HP terminals when they can start a block-mode transfer, but there's no reason you can't abuse it for your own purposes. -Frank McConnell

cw2dmk 1.6: now does RX02 also

by tim.mann＠compaq.com

I've updated the cw2dmk program to version 1.6. This is a program that uses the Catweasel ISA disk controller to read disk formats that are hard or impossible to read with an ordinary PC floppy disk controller. The new version adds a few features, among them the ability to read the DEC RX02 double density format. See http://www.tim-mann.org/trs80resources.html Source code is included under the GPL, so those who prefer to build their own hardware instead of buying a Catweasel (let's not start *that* debate again) may find it of some use too.

Silent 700 Model 707

I picked up a TI Silent 700 model 707 recently (a nice, small variant with built-in modem, see http://pobox.com/~fmw/misc/Silent700.jpg), with hopes of converting to use as a direct line serial terminal. Before I open it up and poke around, does anyone already know how to do this? Portwise, there are two RJ11 ports (phone&wall) and a 6-pin acoustic coupler port of unknown pinout.

preserving / ressurecting old docs?

by mrbill＠mrbill.net

As mentioned previously, I've registered DECDOCS.ORG, and have started the tedious task of scanning in all the documentation I have. I'm about halfway through scanning the '69 DEC Logic Handbook (positive logic edition), by laying the book as flat as possible (not using the scanner top cover), and scanning 2 pages at once. Some of the pages are starting to come unglued, and I'd like to avoid destroying the book while archiving it. Any suggestions on what to use to re-glue the pages, or rebinding, etc? I've got quite a pile of these handbooks and will be doing the same (scanning) to them, but this is definitely the oldest / most fragile handbook in the collection. Thanks for any tips.

I'm currently working on a home automation project using OPTO22 technology. I have found them to be easy to interface, flexible, cost effective, and very reliable. The devices are controlled via a RS422 serial interface (easily converted to RS232) and drivers are available for a number of OSs including DOS, WINDOWS, and Linux. The protocols aren't that complex so writing your own driver, if one is not available, wouldn't be too difficult. Most of the work I've done so far is basic experimentation and prototyping. I currently have a OPTO22 controller interfaced to a HP 9000/832 running HP-UX 10.20. It can turn on and off a few lights, measure the temperature in the house, etc... All the collected data is captured into an Informix DB. The application(s) are written in PERL / CGI and I have put together a rudimentary web interface. I don't have a static IP otherwise, I'd publish the address so others could see the system in operation. My ultimate goal is to build an automated Printed Circuit Board drilling machine using a classic HP 3000 MPE computer running COBOL. I'm not sure if OPTO22 is suitable for that application or not, I'll need to do a lot more experimentation to make that determination. If it's too difficult, I may wind up using a STD BUS computer as a smart controller/interface between the drilling machine and the 3000. FWIW: All the hardware I'm running is over 10 years old so, it is on topic. With the exception of the 9000, most of it is closer to 20 years old.

So, that shouldn't be too big a hurdle. Since I've never done any terminal I/O programming on the 3000, I decided to start with the 9000 which is much more familiar. Once I have a proof of concept running, I can port it back to the older box.

Maybe there would be a way to load archival quality ink into an inkjet cartridge and then print the documents on acid-free paper. I purchased 3 non-working HP 1200C printers for $20, included cartridges. They have cartridges for each color ink. I'll bet they might clog if not cleaned correctly. You could also perhaps find pens for a HP or other plotter containing archival quality ink and then plot the documents on acid free paper. I know you can get acid free plotting paper, the land plats I occasionally see are drawn on linen or cotton paper. I've seen 60 year old copies that look great. The modern ones are drawn by a plotter. Hire a team of scribes to read and transcribe the documents on vellum, any illumination would be a plus.:) After some thought and research I have found the following: Pointer to image permanence institute at Rochester Institute of Technology. http://www.rit.edu/~661www1/ Pointer to archival quality inks for inkjet printers. http://www.tssphoto.com/sp/dg/archival_inks/color.html Pointer about lifetimes of inks and papers for inkjets, may be more image oriented than text http://www.tssphoto.com/sp/dg/news/Wilhelm062000.pdf Mike mmcfadden(a)cmh.edu

The sticky bit would be that the 3000's terminal I/O is essentially one-way-at-a-time: if the terminal device doesn't have a read request posted, then most data sent from the attached device will be discarded (the exceptions being break and subsystem break indications). And trying to do anything else with the terminal device will involve aborting the read request, doing the something else, and starting a new read request. If the OPTO22 protocol can work around this, you're probably OK. Otherwise, you will probably need to build a front-end processor of some sort. If you have questions, feel free to ask, but my COBOL is rustier than my SPL, and so I will probably present terminal I/O examples in the latter with heavy [ab]use of MPE intrinsics. -Frank McConnell

Bay Networks

You had a really old one; they matched Motorola pretty close as far as processors, eventually being one of the few big adopters of the 68060. Backplane ran down the middle. You plugged a processor card in one side, and a ports card in the other, for each slot. Ran from, as I recall, a one slot fixed unit to a 13 slot monster (BN/BLN). The OS they ran was loosely multiprocessing, with an image running on each processor card. This allowed you to reboot a single processor board without bringing the whole box down (well...there were caveats, especially if you were running OSPF). Nice boxes, in many ways better than the competing Cisco product. As an aside, unless you were really good at remembering SNMP OID strings, you configured the things with a tool called Site Manager. This is *still* one of the worst pieces of software I've ever used; they've done nothing to fix it in a decade. And every different version of the router code required a different version of Site Manager; little or no forward or backward compatability. >Bay have since been bought by another companym which in turn has >been bought by yet another, which made finding information about >it quite impossible.

That router was actualy produced by Wellfleet, who later merged with Synoptics to form Bay Networks. Bay was later purchased by Nortel Networks, who is now in the process of trying not to go out of business. A search for "Wellfleet router" should give you sufficient info. Ken Seefried, CISSP

BIG haul of DEC docs!

by mrbill＠mrbill.net

I just got an incredible haul of DEC docs in the mail. Once I get through scanning these and putting them up as .pdf's on DECDOCS.ORG (which I just registered), the actual handbooks, etc, themselves will need a good home, and I dont have space for them - but I refuse to toss stuff like this away. I'd like to trade them for other DEC PDP stuff if possible. So, if anybody's interested, please let me know. I'll be done with these in a month or so, assuming I get plenty of time to use my scanner. The list: Everything is in "Good" or better condition, given some yellowing of the pages due to age, of course. Only one of the handbooks has a torn cover, and its only slightly dog-eared. Handbooks: Year Title ------------- 69 Digital Logic Handbook 70 Digital Logic Handbook 70 Laboratory Computer Handbook (PDP-12) (x2) 70 PDP-8/E Small Computer Handbook 71 PDP-8/E & 8/M Small Computer Handbook 71 PDP-11/45 Processor Handbook 72 PDP-8 Programming Langugaes Handbook 72 Microcomputers and Memories 72 Logic System Design Handbook 72 PDP-11/40 Processor Handbook 72-73 PDP-11/45 and 11/50 System Maintenance Manual 73-74 Digital Logic Handbook 75 PDP-11/70 Processor Handbook 75-76 LSI-11 PDP-11/03 Processor Handbook (x2) 75-76 Digital Logic Handbook 76 RK11-D & RK11-E Moving Head Disk Drive Controller User's Manual 76 DR11-C General Device Interface (x2) 76 PDP-11 Software Handbook 76 PDP-11/34 Processor Handbook 76 PDP-11 Peripherals Handbook 76-77 Digital Logic Handbook 77 PDP-11/60 Processor Handbook 78 PDP-11 Processor Handbook (04/34/45/55/60) 78 Microcomputer Processors 78 PDP-11 Peripherals Handbook 79 RSX-11M System Generation and Management Guide 81 VAX Architecture Handbook 83 Cables: Handbook for the System Builder 83 PDP-11 Software Source Book Vol. 1: Application Software 83 PDP-11 Software Source Book Vol. 2: Systems Software 83 RSX-11M Mini Reference (in mini binder) 83-84 Micro PDP-11 Handbook 84 ULTRIX Software Guidebook 88-89 Software Handbook Catalogs: Year Title ------------- 82 DECdirect Spring 84-85 DECdirect Winter 87-88 DECdirect Plus Summer/Fall 88-89 DECdirect Plus Summer/Fall 88-89 DECdirect Plus Winter/Spring 85-86 DECdirect Plus Fall/Winter 84 Add-Ons and Upgrades 83 (May) Emulex Controller Handbook: Communication and Peripherals The Software Dispatch Review (bug reports): Year Title ------------- 1974 RSX-11D (Sep, Oct, Dec) 1975 RSX-11D (Jan, July) RSX-11D V6A (Oct) 1976 RSX-11D V6B (Jan) RSX-11D / IAS (Feb, Mar, Apr, May, Jun, Jul, Sep, Oct, Nov, Dec) 1977 RSX-11D / IAS (Jan, Feb, Mar, May, July, -- Bill Bradford mrbill(a)mrbill.net Austin, TX

Hey, I used to do distribution centers: sortation conveyors, vertical and horizontal carousels, pick stations, etc. We used Quatech boards with Opto 22 modules stuffed in IBM PS/2 Model 80s which we stuffed in turn in big Hoffman cabinets, and, contrary to my specs, unventilated. They ran like gangbusters! We'd gone in to Rose's Distribution center down in Raleigh-Duram area, and found they had to keep a $250,000 inventory of spares *just* for the custom controllers they used. We figured it would be a lot cheaper to keep a couple Model 80s and some Quatech I/O boards around. We were told that if we botched the timing of the sortation conveyor, that the whole line could "explode"; the contractor said he'd seen conveyor rollers embedded in a warehouse ceiling, once... Lights going on and off, arms swinging lanes shut, packages shuttling off into other lanes, etc. Some of the most fun I've had in computing! And all on-topic, as everything described in the list is > 10years old. Regards, -doug q

Sounds quite similar to some of the older 3Com kit, such as the Netbuilder. I've not seen much old Bay Networks equipment, but if it's like the Netbuilder, then it was a modular device into which you could put various interfaces (on the Netbuilders, each has it's own processor, and the main board is used to provide management facilites). Mine has FDDI, 10baseFL, a couple of AUIs and BNCs for 10base2. It boots from a 4MB 3.5" ED floppy, and I use it as a router (depending on what you put in, it can be a repeater, bridge, or router). > Bay have since been bought by another companym which in turn has been bought > by yet another, which made finding information about it quite impossible.

Virtually no chance of finding such in a charity shop - much better chance at a boot fair (still not brilliant, but I tend to see Acorn stuff (Beeb/Master/Electron) at about 1 sale in 3 - Spectrums, Amigas, and STs are more common. Macs used never to be found, but I have seen quite a few recently. If you have use of a car I can let you know the locations of 4 or 5 big boot fairs in Essex.

Hungarian minis

by optimus＠canit.se

My, this is certainly interesting, Hungary produced minis (mainly DEC clones, but developments of their own as well) for twenty years: http://www.telnet.hu/hamster/tpa/e_index.html I particularly recommend that you have a look at the Quadro, it is such a beaut! -- En ligne avec Thor 2.6a. I installed 7.6.1 on my Color Classic too. It has 6mb ram now, and no FPU yet. Things really slowed down when I installed the Appearance extention and control panel. But now the GUI is OS8ish! ;) That little creep is so cute, I'll probably leave instructions to have it made my urn. It'll hold my ashes, and still continue to function as a computer ;) iVan

Random change WTT: KA694

by cmcmanis＠mcmanis.com

Hi Everyone, on my wish list is a KA694. This was the CPU in the VAX 4000/705a and is basically the fastest Q-bus enabled VAX you could buy. It bookmarks the series (which starts with the MicroVAX I). I've got other VAXen I could trade for it including 4000/200 or a VLC or a 3800, etc. So if you are looking to round out your collection here's your chance! :-) --Chuck

Recent cleaning of computer equipment

by rmeenaks＠olf.com

Hi, I am sorry if some of you guys missed out on the recent transputer stuff I gave away. In a month or so, I will be in London picking up 3 large boxes of transputer stuff (including an original mint condition IMSB001 in its original INMOS blue bag!). Due to my limited space, I will be giving away any duplicate books, software, etc to anyone who wants it. In the near future, I will also be cleaning out a warehouse full of transputer stuff (or whatever is left of it), so whatever I dont need, I'll definitely pass it along FREE OF CHARGE. I just dont have the heart to throw this out and I just cant get myself to post this on ebay especially when good people have donated all this equipment for free. I only ask that whoever wants this, just limit yourselves to *ONLY ONE* piece of equipment so that we have enough for everyone....

NeXT cube problem fix

by mtapley＠swri.edu

All, I think I can finally report what was causing my intermittent NeXT cube "unexpected kernel page fault" crashes. Up-time is now over 240 hours and counting. The problems were heat, and bad ventilation. The short story is, I had the fan reversed (to blow into the cube) and had a very leaky enclosure as the first step on the cooling air path. This was due my installation of a floppy drive looking out through an optical-drive-sized aperture in the front of the cube. Clue for NeXT cube owners: seal up unused apertures and air leaks in the front of the cube. The air needs to go into the drive bay, down into the power supply, out into the motherboard bays, then out the bottom of the machine. In my case, sealing apertures alone didn't do it - I ended up putting the fan back to its original flow direction (exhausting from the cube, so that the CPU board gets the cool air *first* as it is pulled in >from under the cube, rather than last as it goes out via the power supply). I also sealed up the optical and floppy apertures completely, using blocks of black foam rubber (which I'll pull temporarily in order to use the drives as needed). This may eventually cause trouble with the optical or floppy, YMMV and I don't have any long-term experience with it. I'm hoping it will minimize dust build-up in the optical, which is the original well-known reason for reversing the fan. Hope this is helpful, and many thanks to the list members that helped me with hard drives, parts, etc. The "long story" of all the stuff I tried and why I tried it is available on request, for the next few weeks at any rate (until my WORN cranial storage system has purged the details....). - Mark
