Foxboro PCP-88 (PDP-8)

by foo＠siconic.com

According to this FAQ: http://www.faqs.org/faqs/dec-faq/pdp8-models/section-2.html ...the PDP-8 was OEM'd to a company called Foxboro Corporation that re-badged it as the PCP-88. Has anyone ever seen a PCP-88? I would assume it is functionally and physically equivalent to a DEC PDP-8?

by xds_sigma7＠hotmail.com

Hmm... core and and a single-chip 12-bit microprocessor sounds pretty unlikely.. Plus, I'm fairly sure Fabritek made its own computers at one point in time, and I doubt they were clones of anything..

I think that's out of the question, since it's embedded deep in another non-computer-related thing that hasn't been made since the late 80's. > This is why it's much more interesting to deal with OLD computers. I agree, but my aim is to either re-program this thing, or replace the embedded computer completely with something that does work in a well documented way. It will require interpreting some (simple, open/closed and possibly some "timed pulse" kind of things) signals from other equipment, interpreting the signals, and displaying the results on a pair of matrix displays. One is possibly twenty-something by twenty-something, the other 8 or so by maybe 64. Of course, I've also thought about replacing the matrix screens with an LCD of higher resolution. The thing is, I'd rather see about just writing new code for it, but to do that, I need to figure out just what I'm looking at. Another related question is, assuming that this were an embedded ASIC from that era, what could I hope to find inside? Might it have its own internal PROM to store the program? (In which case, I'd need to find a replacement, or use a different chip...)

One SCSI tape connected to 2 hosts?

by bob_lafleur＠technologist.com

I've noticed that my MV3100's SCSI host ID's are set to 6 - I thought this odd, as host ID's are usually 7. Are all MV3100's set to 6, or is mine unique? Anyway, I thought since my PC's host ID is 7, I could connect my SCSI tape drive to both systems. So I ran a cable from one connector on the back to my PC, and a cable from the other connector to my MV3100. I figure it's a properly terminated chain, as each host controller is terminated (I know the PC is, I assume the MV3100 is). It *seems* to work OK. But can anyone tell me for sure if this is "legal"? I'm sure I'm looking for trouble if I try to use the same tape drive from both systems at the same time, but as long as I don't do that, is this an okay setup? It would sure beat changing cables every time I want to move the tape drive from one system to the other. - Bob

RT11 & RSX cd images - additional site

by jwest＠classiccmp.org

I noticed that downloads of the ISO images for RT11 & RSX freeware from Tim Shoppa's website are slowwwwwwwww. I'm not sure if he has a really slow internet connection, or if he (or his ISP) is throttling bandwidth (I suspect the latter). To provide for faster downloads to anyone who wants it, I am copying the RT11 & RSX freeware ISO cd images to www.classiccmp.org/PDP11 They should be up there sometime tomorrow morning, don't download them from me before then or you're likely to get a partial image. And you can bet you'll get more than 14kbps from my servers :) Also, if you only want portions of the freeware CD's rather than the entire ISO image, the entire contents are already at that URL in natural (non-ISO) form to download individually.

new toy DG Nova 4X

by rigdonj＠cfl.rr.com

I went by a surplus place today and found the remains of a DG Nova 4x that they'd already scrapped. Further searching revealed a 4x that they hadn't gotten to yet. I grabbed it, the floppy drives (8") from both units and the front panels from both and the CPU and a couple of other cards from the first unit. I did leave behind the hard drives (that may have been a mistake). Does anyone have info on these? Joe

Warner /Amex "QUBE" set top box

by truthanl＠oclc.org

I think Bank-One and OCLC also had some research resources commited to the early interactive cable project. I recall we used to have some proto-types of set top boxes with an interactive cable banking function somewhere in the penthouse. Mid to late 70's - I think we trashed 'em. Some of the upper management was interested in interactive communicatoin >from homes - but it became obvious that it was difficult to incorporate with our library based mission. So our research was based on cable broadband network technology study - but I remember we had proto-type boxes - which also had a banking sponsor. Larry Truthan - Digest Subscriber

Cool IIgs find

by jrkeys＠concentric.net

At local thrift last night I got a Apple IIgs that had a ELINA fan and 20 meg harddrive combo mounted were the normal power supply goes. Also inside was a AE TRANSWARP GS card, AE VULCAN controller card for the HD, and a AE RAMKEEPER card with 2 Apple ram cards mounted to it. There was a dryfit A200 ext battery Sonnenscheen with it also that works with the Ram card? The cables, mouse, and keyboard also came with it and all or $12.21. I will have to go down to the shop and get a monitor to test it with. At the Goodwill I got a Radio Shack Electronic TV Scoreboard in the box without manuals:-( At another thrift I got a Genesis 32X unit for $3.93, Actimate Arthur by Microsoft, A new unopened package from Teledyne with a early Data Processing Symbols Template. There several other goodies but they are too new to list.

RS/6000 7013-580 troubles

by pat＠purdueriots.com

I know this is just under the 10yr rule, but it's pretty close, so please bear with me... OK, I've got the SCSI drives from the 55L mounted in the case, hooked up a terminal *and* keyboard, and this is what the LED display shows: 120 124 400 When 400 is displayed, the led next to the power switch goes off, the rs-232 port no longer has output voltage, and the machine just sits there. No playing with the reset button or smashing of keys on the keyboard or terminal will wake it up. Anyone have any ideas? The config is: 2-1 Ethernet card 1-9 Video card 4-4 Single-ended scsi-2 card 128MB RAM CDROM drive floppy drive 2x2GB hard drives (3.5" HH) which seemed to at least spin up in the 55L. -- Pat

[CCTECH] HP C19 calculator - power requirements?

Hello: Can someone tell me or point me towards a site with information on the power requirements for a HP C19 printing calculator? I've got one which I'd like to sell, but I'd like to see if it works or not first. It appears to be in decent shape, tho the carrying case is getting ratty. I see on the back it says "5V" and "1W", but the connector (I assume for a AC adapter) isn't labeled, and it has no power pack.

A VAX 6610 is rolling toward my garage ...

by gunther＠aurora.regenstrief.org

Hehe, there goes the last VAX out of my workplace, and right into my garage. And its a 6610! That means I will need to add in a few processors, but there is my NVAX. Much work is before me. I should get Ultrix 4.2 ported to it starting with the 6000-400 files. It can't be so hard after the 6000-500 runs... We'll see. Does anyone have the processor internal registers for the KA66A? With some luck we can drop in just a very small set of kernel files that can be reused under Ultrix 4.5 binary. For NetBSD it will be a little harder to replicate all the missing stuff. I think I will want to set up a fast cross compiling or native VAX box for that first. That also means that a 6400 will become free on relatively short notice. This one goes to Micheal McCabe, if he wants it (?) I am a bit reluctant yet to convert the 6400 to a -600 so quickly after I barely set it up. I guess I will take some time to actually do the conversion. But in a matter of 4 weeks after I took her home, I should probably get rid of that extraneous then 64x0 cabinet. (the 'x' depends a little on how I will distribute all the CPUs.) Also, there are the XMI and VAXBI backplanes (with some defect, but certainly not everything on both of them) free for the taking. They aren't claimed yet and that means I will decompose those shortly. cheers, -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

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...

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

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

by mbg＠TheWorld.com

>OK, I now have a bootable RX-50. My question is what is the difference >between DL.SYS and DLX.SYS drivers? Is the non-x version unibus and the >with-x version qbus or something? 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.

I hate Radio Shack

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. You might be able to get more information from their sister comapany, Lindis: http://www.lindis.co.uk, or from Jack Lillingston at Castle Technology: http://www.castle.uk.co/ (no that's not a typo, it is uk.co not co.uk) -- Pete Peter Turnbull Network Manager University of York

VERY good weekend

by doc＠mdrconsult.com

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.. (and the pictures show the display as yellow - its actually orange..) Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

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. Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

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

by mrbill＠mrbill.net

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

Philips and auction finds (was: Re: I hate Radio Shack)

by Antonio.Carlini＠riverstonenet.com

>I actually tried that with one local shop, and they flat out said no. Its >quite possible that the Philips/Magnavox service docs can't be printed >(via normal means, anyway), but only viewed from those cdroms. If they can >be printed, its possible that the service shop has a limit as to how many >pages they can print (or even view) from those discs. PDF files can be marked to prevent printing, although I think it's down to the software to honour this. Limiting the number of viewings seems a little daft - I doubt that anyone does this! Antonio

Does RF output equal Composite?

by doc＠mdrconsult.com

OK, now that I've exposed myself as an inveterate non-gamer. If I have RF output (VHF Channel 2 or 3), can I run a composite cable into the Video In jack of my VCR and get a picture? Doc
