There are a few programmes that allow you to take a "screen shot", which means they produce a (.bmp .jpg...whatever) file that shows what you had on your screen when you press some key. The one I have was part of the Corel family...unfortunately, I haven't used it a long time and I'm not home now to check its name. There could also be something like this out as freeware, but I'm not sure on this. Even if it's a bit complicated, this would at least allow you to print the contents of those manuals the original viewer doesn't want you to. Legality of such operations is another problem; I do not want to encourage illegal actions. But I also don't want to see perfectly repairable appliances go to the dumpster. Choose your way...

OT: Ripping Phone Books (was RE: Computers in Public Xport)

by Robert_Feldman＠jdedwards.com

Ripping a phone book in half is really quite easy if you know the trick. Just break the spine (it helps if the humidity is low, so the paper is less flexible) first. Once the pages are torn at the spine, you can rip them the rest of the way. -----Original Message----- From: Sellam Ismail [mailto:foo@siconic.com] Sent: Thursday, June 20, 2002 11:54 AM To: cctalk(a)classiccmp.org Subject: Re: Computers in Public Xport <snip> I always did want to learn how to rip a phone book in half with my bare hands but never got around to ordering.

Acoustic delay line??

Hi I'm going to make a wild guess. This was a flash tube used to sychronize a neon light computer. Anyway, I don't think it is a delay line.

Bulk Tape Eraser

by mythtech＠mac.com

I just found a box of stuff that hasn't seen the light of day since my company moved to our current building some 15 years ago. In it was a Bulk Tape Eraser. The box pictures it being used on 5.25 floppies (as well as an 8 track tape and reel to reel tape). Is it safe to use on floppy disks? I have a stack of HD 3.5's that I want to blank out. Previously I just run them thru a computer to format them, but if a bulk tape eraser can be used, it just saves me the trouble. Also, how exactly are you supposed to use one? It has been as long since I used one (probably this same one, used to use it to blank reel to reel audio tapes). I thought I remembered that all you do is turn it on, hold it over the item for a few seconds, wave it back and forth a bit, and that was it. The item would be erased. I just tried this one on a VHS video tape, it doesn't seem to do anything to it. The picture is slightly distorted, but the tape is certainly not blanked, not even close. I left it on for a good 30 to 45 seconds (the label on the side of it says 1 minute on 20 minutes off, so I didn't want to go beyond 1 minute). It has a momentary switch on the handle, so it clearly isn't designed to be left on very long. It makes a slight humm when on (and vibrates just a touch, nothing visible, but you can feel it in your hand) so I assume it is working. However, this is a Radio Shack brand item, so who knows if it is doing what it should considering it is probably over 20 years old. Any clues? -chris <http://www.mythtech.net>

[CCTECH] WTD: Datasheets for old Sierra modem ICs

by philpem＠dsl.pipex.com

Hi, I've just finished pulling an old Sierra Semiconductor FSK modem chipset off an old modem board and I've hit a brick wall - I can't get any datasheets. Sierra (now known as PMC-Sierra) don't have the datasheets, their disti (Memec) don't have them... The only site/company that does have them is FreeTradeZone (www.freetradezone.com), but I don't fancy paying $10,000 per year for maybe two or three datasheets a year. BTW, the ICs are: SC11011 SC11026 SC22201 Anyone got datasheets for these things lying around? Finally, anyone know how to straighten pins on a QFP packaged IC without breaking them? I've got a Motorola DSP (QFP100 package) but I managed to bend some of the pins when I desoldered it...

Network card for LaserJet

Those hubs are the only time _I've_ seen RJ-45 >used for serial communication. Various terminal servers use RJ45 for serial comms. One of the selling points of CAT5 was that you wire your building once with CAT5 and then can use the same wires for voice and data. The data was usually either ethernet traffic or serial comms (for printers and such). The connectors were invariably (at least in my experince) RJ45 for both ethernet and serial (and ISDN too).

how to preserve old RL01 pack data?

by fran＠hexamon.org

I have some old DEC RL01 packs with PDP-11 diagnostic utilities - these are DEC originals: AX-E380L-MC DLDP+DIAG#1 + DECX A1 SYSTEM A AX-E441L-MC CZZLBLO DLDP+DIAG #2 + CPUTST + DECX B1 SYS B They won't last forever, and I don't have any spare media to back them up to, so I'd like to archive this software onto my PC (for posterity - or perhaps to make available to other hobbyists for use in the emulator, though I'm not sure whether the Mentec license would cover this - it does say "and associated utilities" however). The question is, how can I get a copy of a pack as a binary image onto the PC ? (to load in simh for example ?) I have a working serial port, and I can run kermit OK on RT-11. However, even if RT-11 will read the pack in DL1: (and I'm not even sure of that), how can I persuade kermit to take a copy of DL1: as an image ? I haven't found a way of doing this. Simply doing "get DL1:" doesn't seem to work. Is there any kermit-like software out there that has a PC client and can do a disk image transfer ? Thanks in advance, F

DEC Pro350

by pat＠purdueriots.com

EET'S ALIVE! Well, I finally hobbled together a 'console cable' that connects its monochrome output to my TV and to a LK201 keyboard. Now I just could use a 'better' OS for the thing than P/OS. [Also, I could use soemthing that told me how much memory it has in it...] Has anyone ever hacked RSX-11M or RSX-11M+ to work on it? Are there any guides for RSX-11M(+)? How should I cure my insanity? :) Is VENIX worth trying on this thing? -- Pat

Making RT-11 bootable

The dd.SYS form of the driver is for the SB (formerly SJ) and FB monitors (kernel, for unix weenies :-) The ddX.SYS form of the driver is for the XM (XM, ZM, ZB) monitor(s). These last monitors are the ones which have directives for controlling extended memory (anything beyond 64kb) and the drivers know how to get data from, and put data to, user buffers in extended memory.

any advice on IMSAI testing/repair?

by dpeschel＠eskimo.com

Sorry, I don't know the exact model number (it belongs to a friend who got it from his dad). It hasn't been turned on in a long time -- what is the procedure for slowly bringing it up to make sure nothing gets fried? I imagine it would be to check the power supply and backplane wiring, then the CPU card (including the voltage regulator), then memory (including the voltage regulators), then other cards -- and the front panel has to be checked at some point too. I could use more specifc directions, a list of potential problems particular to the IMSAI, etc. Thanks, -- Derek

One SCSI tape connected to 2 hosts?

by pete＠dunnington.u-net.com

On Jun 18, 13:40, Geoff Reed wrote: > There are SCSI sharing devices out there that will allow one device to be > hooked to 2 machines concurrently. You can do it directly providing the controllers (and their hosts) are well-behaved (which lets Windows off the hook). Back in the days when a SCSI disk of any size cost nearly as much as the computer you might want to attach it to, one enterprising company produced a system for the Acorn Archimedes which allowed six Archimedes computers to share one SCSI disk (and, I think, to "talk" to each other). I saw it working at an exhibition, and I think it was made by Lingenuity.

VERY good weekend

Well. I've been working on, and cleaning & testing, the weekend's finds. It was a nice haul. The aforementioned Macintosh System Software bundle, in shrinkwrap. Way too much, but it's eBay Bait from hell. $6.99 An Atari 1040ST with SC1224 display and mouse - works great, no burn-in, floppy reads & formats perfectly. $5.98 A Telex EB6 Dead Reckoning Computer. Telex still sells them, but I'm sure this one's at least 15 years old. Not a computer, but computerized, and the perfect ClassicCmp Collector's accessory -- 1991 Ford F-150 with Straight-6 EFI and overdrive manual transmission. It's on its 4th trip around the odometer. 328,755 true miles. Doc's in love. Free. By the time it's street legal I'll have $75 into it. Doc

VS4000/60 and VRE01 problems

by mrbill＠mrbill.net

Anybody had luck hooking a VAXstation 4000/60 with "GS-2" (?) graphics adapter up to a VRE01 flatpanel? I finally got the VS4K from Doc today (thanks for dropping it off, BTW, hope that mono video cable works for you), and got around to hooking it up to the VRE a bit ago. However, all is not right - there looks to be a scan rate/resolution mismatch, and I cant find ANY dipswitches, etc, to set.. Suggestions? Links to the 4000/60 owners manual possibly? I've got pictures of the results: http://gallery.mrbill.net/view_album.php?set_albumName=vre01&page=2 Any help appreciated. I'd LOVE to get this display working..

RKV11D - RK05 media to CD or other DEC media

by jhfinepw4z＠compsys.to

Last year, I acquired an RK05 drive along with a number of very old RK05 packs with RT-11 files. Since these distribution are all older than V5.03, they are covered under the Mentec license which allows usage under the SIMH emulator. Last week, I was able to borrow an RKV11D Qbus controller and copy most of the 17 packs (there were a few packs with bad blocks) with the RT-11 files to a CD. Within a few months, it should be possible to make these distributions available under the emulator license, just as V5.03 and V4.00 or RT-11 are now. In addition, while I still have the loan of the RKV11D, if there are any users with RK05 media that wish to rescue the files, I will be able to do so providing the media are still in readable condition. If the RK05 media are in satisfactory condition and I only need to read the files once for the COPY and a second time for the verification (there are no bad blocks), then there will only be a nominal charge for the destination CD or other DEC media that I am able to use such as RL02 or TK50 or TK70. If there are some "difficult" blocks that I am asked to try and recover, then I will also charge for my time.

[jsbragg@pacific.net.au: An old VAX may need a new home...]

Contact Scott directly. ----- Forwarded message from Scott Bragg <jsbragg(a)pacific.net.au> ----- From: "Scott Bragg" <jsbragg(a)pacific.net.au> To: <mrbill(a)decvax.org> Subject: An old VAX may need a new home... Date: Thu, 20 Jun 2002 04:05:44 -0700 I few years back an old friend who I know longer have contact with gave me an old MicroVAX and additional storage unit. I found your site just before heading to bed so may pick this conversation up later and provide more details. The system stopped booting but I think it was a minor problem so tried to repair it myself. However just at that time I found I had to move house so the machine has been sitting in my second bedroom for 2 years collecting dust with some parts not attached. I'm moving house in 1-3 months time and won't have room for a lot of my old equipment, so if I cannot use it I'll either give it away or throw it out (however this VAX is very heavy so maybe I won't be throwing it as such <grin>). I may also have a couple of manuals somewhere too. I'm in Erskineville, Sydney, Australia - so if you know someone who either can help me get it running again and/or wants it, let me know. As I said, I'm heading to bed now, I'll provide more useful details in the morning. Regards, Scott Bragg ----- End forwarded message ----- -- Bill Bradford mrbill(a)mrbill.net Austin, TX
