I am currently fooling about with some HP9000/200 series machines, specifically an HP9816 and an HP9817. The serial ports of these machines are on 50 pin microribbon connectors (like SCSI connectors (!)). They're RS232 levels (1488 anmd 1489 interface chips). I believe the HP98626 RS232 interface card for these machines has the same connector. Needless to say I need to make up adapter cables to DB25 connectors. I assume HP sold said cables at one point, but I can't find the wirelists in any of the obvious manuals on hpmuseum.net (OK, if it's hidden is, say, a printer manual, I'll not have spotted it, but I've read just about every manual for the machines, the interface cards, and the BASIC). I have pinouts for the microribbon connector, so I can work out where most of the wires should go, but there are a few signals that seem to be non-standard (they're driven by I/O port lines inside the machine so what they actually do is software-determined. They're probably not important, but in the interests of compatability I'd like to wire them as HP would have wired them So does anyone have : 1) Wirelists of the original HP cables. I assume there was one going to a DB25-P (male), wires as a DTQ, that would be the most useful to me, but _any_ would be a start 2) The original cables that they can 'buzz out' and produce a wirelist from. 3) A 'spare' cable thet they can sell Thanks in advance for any help -tony

Another IBM 5110 system

by tosteve＠yahoo.com

I just picked-up an IBM 5110 in Las Vegas. It cost me a few hundred, but a nice system (no printer). Unfortunately, I had the leave the giant floppy drive chassis there - too big for the car - I think it weighs around 150 lbs. I will drive out there again in a few weeks (with a bigger vehicle) to bring it back to southern California.

Wanted: N8202N datasheet

by v.slyngstad＠verizon.net

Hi, I am looking for a datasheet for the N8202N or equivalent. It would have been described in "Digital 8000 series TTL/MSl". It was apparently manufactured by Signetics and equivalents seem to have been available from Motorola and others. I have the pinout for the device. What I'm looking for is whether the clock is edge or level sensitive, which edge or level, and maybe something about setup and hold times, etc. (This is to help design replacements for some hard-to-find old DEC gear.) Thanks! Vince

Floppy disc reader/writer status report

by classiccmp＠memory-alpha.org.uk

Hi, >....But USB has been flaky and an incompatibility nightmare. (The >latter being exactly what hardware makers want, of course, because >it sells *new* hardware.) Amen to that. The biggest problem I've had, outside of (the *VAST* majority of) USB drivers which were so buggy as to cause my machine to BSOD as soon as I tried to use the device, is that every time you change/upgrade your OS you need to wait for the hardware manufacturer to release updated drivers....in most cases I've seen these "updated" drivers provide just the bare minimum of functionality in order to "persuade" you to buy a newer device. HP are a prime example, the 64-bit drivers for my printer/scanner/copier only allow the use of the unit as a printer....and a monochrome, text only one at that! :-( > And, quite aside from that, SCSI is far more backwards-compatible.... >....SCSI goes back to the '80s - and, what's more, it's *compatible* all >the way back to the '80s.... Quite. The only compatibility problems I've ever had with SCSI were caused by a couple of 5.25" full height hard drives which refuse to work if *ANYTHING* else is connected to the SCSI bus at the same time (one is a Siemens drive, the other a Fujitsu - I still have them, LOL). Other than that I've always found SCSI to be quite wonderful.... :-) TTFN - Pete.

Old version of Excel for the Mac needed

by rcini＠optonline.net

All: I?m trying to convert some old Mac Excel files I found from college which I think are Excel version 1 files. I have Office 4 for the Mac that I run in Basilisk (under System 7.5.3), but it can?t open the files I have. So, I fired up Mini vMac Plus (with System 7) and tried to run Excel but I get error ?605 which I think is ?memory full? (or insufficient memory). The Mini vMac Plus configuration has 4mb of RAM (with about 3mb free), which should be enough, but I guess not. So, I was wondering if someone has a copy of a slightly later version of Excel (later than 1.0 but before 4.5.2) that can run on a IIci (in Basilisk) that one would be willing to make a DSK/HFV image of? Alternatively, if someone had a copy of the ROM for the Mac SE, I could try that version of Mini vMac. Thanks in advance.

Freecycle stash of Apples found.

by us21090＠yahoo.com

Lots of good suggestions-- Thank you. And many are correct- what to keep depends on what I wish to do with 'em. Sounds like a familiar topic here! I leaning toward a rarer representative/useful machine- A packed II, I guess. I need to determine which cards will work in it and then what maxing it out means in a practical sense. That is, understanding the associated limitations (memory, speed, languages, etc.) I like the idea of a serial card (as a hope to interface with the current world), SCSI (to save on floppy wear and tear), etc, etc. Thanks again.

All, About a month ago I picked a nice stash from a freecycler wishing to clean out. The summary list: Partial Apple II, II+, IIe and lots of h/w accessories and software. The fuller list is at the end of this entry. I'm not a big collector (I have a Obtronix Apple Replica and Kim-1 (another 6502 SBC)). But I thought I'd piece together a nice representative Apple 2 and sell off the rest. I haven't tested anything yet. Question 1: Which to keep: II, II+, or IIe? I need to review Apple system hardware history, but I'd figure the IIe has the most capability, but the II is more significant. Question 2: Which accessories are significant to keep (you know, but hate to say it: "VERY R at RE!!!")? Some things may be rare, but I doubt I'd use them.

Olibetti jacketless floppies...

by julesrichardsonuk＠yahoo.co.uk

Rather an odd find today, tucked away in a box of printer paper: A pair of "Olivetti Minidisks". The flexible disks are around 2" in diameter, but curiously have no jacket whatsoever - just a cardboard sleeve to protect them when not in use. I've never come across these before; any idea what system(s) they're for? Were they something cheap and cheerful for some sort of word processor machine? cheers Jules

PDP-11 Software (Was: Mentec)

PDP-11 Software (Was: Mentec)

by bqt＠softjar.se

To answer a few details in short. PDP-11 licenses (alteast RSX, and I believe all of them) are bound to a specific customer. So they don't transfer along with the hardware. However, DEC did have a license transfer program. It wasn't expensive, and I used it at my end back when DEC still existed. I think it was still possible to transfer licenses after Mentec bought the software and DEC still sold it. What the exact status of this is right now, I don't know. Haven't asked. As for Jay West and Jerome Fine's claims that it's all right just because Mentec haven't set any lawyers on their backs must stand for them. I don't think it's okay, and furthermore, I don't think their claims that it's OK because they think that Mentec knows a lot of things will hold much water if it went to court. But that's just my thoughts. And yes, I do speak with Mentec on business matters from time to time, so I'm not totally unaware of what they do. If Jay West happens to know for a fact that Mentec is aware of the discussions here, and furthermore, have proof that people here are running their software without a license, and choose to not do anything about it, then I think it would be a good thing for him to actually say so, since it actually would strengthen his case against Mentec, if it ever came to that. By playing the "it's not something we're willing to discuss in public" is just idle talk, since it's in fact more supporting of what I'm saying than what he is. But I'll leave it here. No point in arguing. Everyone have to decide for them self. I do notice that noone have yet publicly admitted to violating Mentecs IP rights.

After the NC4000 was created, many realized how easy it was to create a Forth processor with the newer technology in ASIC or programmable arrays. I wonder what has failed on your board. If it isn't the chip, the rest of the board is relatively standard parts. These Forth board were often used as accelerators for PC systems. Several test that showed that these simple processors could run application more than 10 times faster than similar clocked x86 or 68K machines of the time. The RTX2000's were made RAD hardened and used quite a bit in satellites. Much of the speed was because Forth lends it self to a 3 bus architectures that functionally used at least two of these buss on each instruction.

I don't agree in this case. While I usually don't bother, since he's mostly into RT-11, which I haven't used, we're in rather separate worlds. But his assumptions about Mentec are just assumptions. > I should point out something that you dont seem to be aware of (at least > based on your statement above) - a demonstrable pattern of non-enforcement > of license does in fact weaken the ability to enforce it.

Yes, but this is all based on the assumption that the company is aware. Otherwise it's not a point at all. So you should then first of all demostrate that the company *is* aware, and haven't bother taking action. I haven't seen that proven yet, and I'm pretty sure you haven't either... For the company to be aware two criteria must be fulfilled: 1) Mentec must know of this list, and monitor it. 2) People on this list must in no unclear terms make it clear that they are breaking the license agreements or violating Mentecs rights. And as I said before, I haven't seen either of these two proven yet. But to make it easier for Mentec (in case they are looking), how about a head count. Anyone who is using Mentec software without having a correct license: let us all know. Make a public reply to this. That will atleast fulfill one of the two requirements (if anyone will reply to this call out.) > This is also one of several reasons that some - not all - companies are wary > of creating a hobbyist license, because there is some amount of perception > that it will put their ability to enforce a license at peril - or at the > least possibly cloud the issue. Yes. That is true. > On a separate and unrelated point, I believe Johnny (or someone) questioned > whether Mentec is aware of this list, various archives, etc. I can assure > you that they are, just as Jerome intoned. Really? And how do you know this? Just because one ex-Mentec employee occasionally post here, do you think that Mentec knows about it? For all that I wish that a hobbyist program was available, none exist at the moment, and actions and false beliefs like this is likely going to keep preventing it from ever happening... Call me Mr. Negative if you like. I just try to point out things as I see them. You may all disagree. Can't help that. Atleast I got valid licenses. And you can have that too, if you pay for it.

8mm data cartridges

by aek＠bitsavers.org

> I always figure there's a lot less to go wrong in a DLT cartridge than there > is with a hard disk The flaw in this argument is the time it takes to make another copy, which needs to be done at some point to migrate to newer media. You will only know the DLT has failed when you try to read it again. If you care about the data, it should be kept in a form that is easily replicated and verified, and you should assume that any single copy of that data WILL become corrupted or unreadable over time.

OS/8 on-disk structure

by dbetz＠xlisper.com

Does anyone know if there is a scheme for mapping out bad blocks on an OS/8 RX01 disk? I have an image of an RX01 disk that I'm trying to retrieve data from and it seems to have bad data in the middle of a file (4 blocks). Is there any chance these were bad blocks that were mapped elsewhere on the disk? Thanks, David

SC/MP LCDS

by sttaylor＠charter.net

First time post, I to am surprised and pleased to see the Scamp get some post time. I hope you will archive all of the LCDS Kit Documentation you have. (or send it to someone that can archive it) There is VERY LITTLE documentation (and no Original Natl. Semi. Docs) on the net. It looks like more people then you thought will be watching Ebay for your SC/MP auctions. Steve

Mentec

by bqt＠softjar.se

Hi, Rod. Jerome makes some interesting, if strange and faulty assumptions. Such as assuming that since Mentec hasn't complained although people "appear" to have been using and posting about RT-11 on classiccmp list for a long time. First of all, we don't even know if Mentec knows about the classiccmp list, neither if they scan it (which perhaps some people should be happy about). Second, I can't remember that many people actually coming out saying that they are using RT-11 without a license. So I would somewhat ignore Jeromes view on the legality of things. That said, I'll answer some of your questions. "Rod Smallwood" <RodSmallwood at mail.ediconsulting.co.uk> skrev: > > Hi Jerome > > We seem to be converging on our views.

If I had spent > years restoring an old aircraft to flying condition I would not park it > and use MS flight simulator instead! I agree with you. It's fun to actually run the real hardware, and not just play with a simulator. Not the same feel of satisfaction. I still play with an 11/70 here, even though we also have E11. > RT-11, RSX-11M & RSX11-D, and RSTS were all current when I joined DEC in > 1975.

It might be a risk based decision. That is probably one part of it. Another part is that they have paying customers (still) and probably don't think it's a good idea to start giving it all away for free, which means they need to draw up some sort of license that will limit things in a useful way. Doing that costs money, and they probably can't see any profit from it. So why spend that money? > However I'd still like to know what are the answers to the fundimental questions: > > 1. Are Mentec still selling PDP-11 operating system licenses? Yes. As someone who have customers who still buy from Mentec I can definitely confirm that they were still selling ten months ago. Can't see a reason why they should have stopped since then. This is RSX and layered products, by the way. > 2. Are they still making PDP-11 hardware? No. I think they stopped manufacturing "real" PDP-11 hardware, and are now pushing for emulators. However, that is a grey zone. We haven't had a real "true" PDP-11 CPU since the 11/20. All the rest are microcoded. Microcode is also software. :-) > 3. Why have Mentec removed all mention of PDP-11 products from > their web sites. That is a really good question, and one which I don't have an answer to. But I'd like to know if someone else have.

[midatlanticretro] WTD: Morrow Wunderbuss Thinker Toys Motherboard Schematic/docs

by ragooman＠comcast.net

I almost posted a lengthly explanation on the march group list before I noticed you posted the pic on cctech. The power supply in that circuit is a -12V not +12V. The voltage regulator part # on there is a 7912 which outputs -12V. The part that is blown on there is an electrolytic cap, not a zener (note the + sign on each end of the cap). Both of those parts below the 7912 are the same type of part. Caps always dry up and blowout--they don't last forever. That's why it's good to have a Variac when powering equipment that hasn't been on for a long time--a homemade current limiter helps too if no variac is available. But I'm not sure of the value, it can't be very high in value, possibly only 3.3uf or 4.7uf considering the size, this isn't very critical , so long as you keep it in the ballpark. The caps for the 7805 regulator on there beside it are only 2.7uf. I would suggest changing both of them, for sanity's sake--they both might be damaged. The other important issue is to check the traces for damages when you remove the bad parts. They could have burned through creating an open circuit. So you'll have to splice the traces back together if this is the case. Some skinny telephone copper wire always does the trick. And last but not least, is the 7912 voltage regulator. You should check the -12V power before you plug in any cards. =Dan [ My Corner of Cyberspace http://ragooman.home.comcast.net/ ] B.

Mentec

by doug＠stillhq.com

"Don't expect to ever see a Hobbyist License, and don't blame Mentec." Cool - RT-11 isn't that big, is it? If it is only a simple O/S, and a couple of utilities, then why don't we clean room it, and produce an open version. Shouldn't be that hard.

SC/MP LCDS

by river＠zip.com.au

Hi, Yes, I built one of those Miniscamps also. I think I've always had a soft spot for the SC/MP since that time. I bought some SC/MP chips a few years ago and most of them did not work, but a couple did and I built up a small system with 4K RAM, 4K EPROM, 8255 PPI and an 8251 USART. I wrote a small program to test that it all works, and a "Lazy brown fox" message through the serial port. It worked fine, then I got distracted in expanding an AIM65... then I got a hold of a couple more AIMs, and they were broken so I set about fixing them. I guess time just got away and I got more distracted with a cantencerous Central Data 2650 system. So, the home-built SC/MP system still sits waiting for me to write a debug/monitor for it. However, now I've got the LCDS I've got the vigour back and will fix it and also get back to my home built one. I too am interested in any SC/MP stuff that's for sale. river

Mentec

by RodSmallwood＠mail.ediconsulting.co.uk

Hi Jerome We seem to be converging on our views. The simulator is a simple issue. I want to see the old systems run and live again. If I had spent years restoring an old aircraft to flying condition I would not park it and use MS flight simulator instead! RT-11, RSX-11M & RSX11-D, and RSTS were all current when I joined DEC in 1975. The hardware to support them (Mentec excepted) has not been made for at least ten years. The answer may lie a little deeper. I think what may lie at the back of it is if they provide it they may be liable for any damage it does. Licenses do not change laws and the law of the land will always take precedence. It might be a risk based decision. However I'd still like to know what are the answers to the fundimental questions: 1. Are Mentec still selling PDP-11 operating system licenses? 2. Are they still making PDP-11 hardware? 3. Why have Mentec removed all mention of PDP-11 products from their web sites.

While I also agree that eventually RSX-11 and RSTS/E will probably be handled in the same manner, that does not seem to have been the case in the past. In particular, I have the impression that RSX-11 distributions, although officially approved of in the same license as RT-11 for use with the DEC emulator, always remained difficult to obtain. However, since I never attempted to use RSX-11, I can't comment. On the other hand, RT-11 was very quickly available for download as soon as that license to run V05.03 of RT-11 and prior versions was made explicitly known to this list and certain newsgroups. >DEC were quite keen on educational computing and that's how they would >have viewed a hobbyist program. As HP now effectivly own what was DEC I >assume the agreement is now between them and Mentec. > It does not really seem that either HP or Mentec are interested in spending money on lawyers. HP and Mentec do seem to be very concerned that if any of the latest versions of the PDP-11 operating systems which include RT-11, RSX-11 and RSTS/E are made available free of charge and without a formal license being signed to even hobby users for strictly non-commercial use that the result would also be free use for commercial users. At least that is my assumption since I can't think of anything else that might cause a problem. Can anyone else comment on what might happen if Mentec were to allow hobby users to freely run without any restrictions either V05.03 of RT-11 or possibly even all RT-11 software, in particular with regard to commercial users of RT-11 or for hobby users of RSX-11 and RSTS/E? >It seems that many efforts to set up a hobbyist (or collectors program) >have come to nought due to Mentec seeing no profit in the arrangement. > That is also my assumption. It was also my assumption that hobby programs allow students to become capable of supporting commercial systems as well as producing interesting enhancements for and finding bugs in operating systems. As long as the operating system software is still being sold and producing sufficient profit, a hobby program is often a benefit and support to the operating system. Once the profit level becomes too low, starting a hobby program seems no longer useful and perhaps that is how HP and Mentec view a hobby program for the PDP-11 software which Mentec handles. >Needless to say as a DEC hardware collector a simulator is of no >interest to me. > > I am always confused by this viewpoint. Please explain. If you don't really care about the software, then why do you care which software is being used by the hardware? In fact, why is it necessary to run any software at all? I would have expected that the XXDP diagnostics would be more than sufficient to exercise the actual DEC hardware and provide the feeling that the actual DEC hardware is being used. On the other hand, I am quite obviously interested in the functionally of the software and the manner in which the various software components relate to each. As a result, an emulator is often much more useful than the actual DEC hardware. In respect of using E11, about the only real difference that I notice is that the RT-11 programs tend to execute about 100 times as fast on a current 3 GHz Pentium 4 as on a PDP-11/93, including both CPU and I/O, indeed especially disk I/O; the available storage is also likely to be measured in the 1000 times capacity since 500 GigiByte hard disk drives now cost less than the 600 MegaByte Maxtor ESDI XT8760E that I purchased for $ 600 at an end-of-line sale around 10 to 15 years ago. As a result, one of the enhancements that I plan for RT-11 is to allow up to 65536 RT-11 partitions which will allow for hard disk drives up to 2 TeraBytes. Anyone interested? >>Hi All >> I'm a bit confused about this Mentec issue. They bought up the >>rights to the pdp-11 line and even produced some new boards.

The old PVC cable vs. polystyrene box problem

by witchy＠binarydinosaurs.co.uk

Hi folks, Yesterday I picked up a Multitech Microprofessor II* plus some other goodies like an EACA Video Genie and lots of useful Sinclair QL bits, only a 7.5 hour round trip too :) On inspecting the MPF-II's box, I'm guessing it's been sat in a cupboard since 1985 as a lot of the internal walls have reacted badly with the PVC cables, some of them have been eaten through. What plastic can I wrap the cables in to avoid any more damage? Polythene wrap?

Old Subject, Another Twist

by Billy.Pettit＠wdc.com

For those who remain unconvinced about the importance of ESD: http://www.eetimes.com/news/latest/showArticle.jhtml?articleID=199203948 Disk drive heads and media are manufactured using Semiconductor lines, so they have the same problems. Disk drives are worse in fact, since the heads and media are exposed to air during manufacturing. I just saw a study that found head failure to be the number one long term failure. The wear study expected to find bad motor bearings or gasket break down. Instead, MR heads are usually the first item to wear out by a big margin. The study separated crashes from head degradation, so it truly is head wear out. Electronics (PCB related) failures were under .5% of the total. Billy

value of IBM 5110?

by silent700＠gmail.com

I've spotted this nice setup locally, wondering if the guy is asking way too much for it: http://chicago.craigslist.org/chc/sys/322279611.html If the link goes dead, it's an IBM 5110 PC, 5103 Printer and 5114 dual floppy unit. Yeah, I know, it's worth what people will pay for it. But I don't even see any completed on ePay, so I can't begin to gauge the appropriate value. Those big floppy drives are calling me, though... -- jht

Freecycle stash of Apples found.

by us21090＠yahoo.com

All, About a month ago I picked a nice stash from a freecycler wishing to clean out. The summary list: Partial Apple II, II+, IIe and lots of h/w accessories and software. The fuller list is at the end of this entry. I'm not a big collector (I have a Obtronix Apple Replica and Kim-1 (another 6502 SBC)). But I thought I'd piece together a nice representative Apple 2 and sell off the rest. I haven't tested anything yet. Question 1: Which to keep: II, II+, or IIe? I need to review Apple system hardware history, but I'd figure the IIe has the most capability, but the II is more significant. Question 2: Which accessories are significant to keep (you know, but hate to say it: "VERY R at RE!!!")? Some things may be rare, but I doubt I'd use them. For example, the Switch-A-Slot (see http://tinyurl.com/2m8b3e ) Thanks for any helpful suggestions!

Chicago Goose Island Recycling Center

by feldman.r＠comcast.net

I went to the City of Chicago Recycling Center on Goose Island yesterday to drop off some old monitors. They do not sell what they take in, which is mainly PC's, monitors, and printers. Some get fixed up for schools, etc., but most get recycled. In true Chicago fashion, when I asked if they sold any of the intake, the attendant said no, but he had a cousin who I could buy some items from. All in all, not a place to get classic equipment, but a good place to dispose of dead monitors. Bob

SC/MP LCDS

by river＠zip.com.au

Hi, I don't know if you saw the SC/MP LCDS (Low Cost Development System) for sale on eBay (Australia) last week, but I bought it. I've been looking for one of these babies for a long time, and to find one for sale near where I live was too good to be true. Indeed! It's dead. Hehehehe, but it has all the parts and manuals, schematics and ROM listing. So, I guess I'm going to be busy in the next few weeks while I try and trace the fault. It's getting the right voltage, so I am assuming it's a bad chip or a ROM has gone bad. I'll get the CRO onto it and try and read the ROMS to find out what's going on. It came with both a SC/MP I and a SC/MP II processor card. Neither card works in the system so I am assuming it's a main board fault. I got a homebrew SC/MP system and some spare CPUs so I can chop and change and hopefully get this old system running. I'll let you know how I go. river

Some Vax 3800 questions ...

by jos.dreesen＠bluewin.ch

Today I tried out my new (18 year old) Microvax 3800 . (tk70, ethernet, rf31, rf72, scsi ). I removed the KDA50 boards. The system tries to boot into VMS5.4, but hangs because it seems to look for diskarrays that are no longer present. Is it possible to boot into a root mode to change the startup behaviour ? Of course passwords are not available. I am also looking for some brackets to mount the RF's into the BA-213. ( The drives came from a ba-400 chassis ) Or are other smart mounting solutions posssible ? Finally, are DSSI and SCSI terminators identical ? To make place for the 3800, a Microvax II/gpx has to go . Working, needs new disk, located in Zurich, Switzerland. Jos Dreesen

DEC Pro380 disk drives

by chd_1＠nktelco.net

Can the Pro380 be used with RX33 drives in place of the RX50? The Pro technical manual doesn't say anything about the RX33. It also doesn't say that there is a way to change the floppy data rate, so I am guessing it does not support them. Can the Pro380 be used with any ST506/ST412 type hard disks or just RD50, RD51, and RD52? I have a couple RD32 and some non-DEC drives and am curious if any of the could be used with it. How do you format a drive for a Pro? I never noticed any support for Professionals in XXDP? Was there a utility in P/OS for that purpose? -chuck

DEC XXDP ZRQC?? source listing

by chd_1＠nktelco.net

I am looking for the source listings for the RQDX3 disk formatting utility ZRQC from XXDP. I am wondering if they are part of the diagnostic micro-fiches. I think there are a couple people on the list with copies of the fiches. I want to try formatting some non-DEC hard drives. A search of the web shows that some have been successful in patching the drive description tables to format a drive with non-standard geometry, but I think getting the parameters for Bad Block Replacement right is the tough part. Maybe the formatter sources will help. -chuck

That Mockingboard is a soundcard I believe. It is a sound card. I forgot to mention that you might want to keep it. ISTR it's something like a 4-channel software-driven multi-voice sound card - unusual in a day when "sound" was either a CB2 shiftregister output from a 6522 or a single-bit like the speaker output on a PC. They weren't very common, but back in the day, they were cool to play with. -ethan

That horrible computer foam

by ian_primus＠yahoo.com

As I have been collecting computers, I have noticed that some pieces of equipment like printers and the like, contain a lot of this awful foam stuff, most likely for noise deadening. Time has caused this foam to break down and turn to gunk, or at least a soft, squshy material that does not spring back. It also crumbles. IBM foam seems to be the worst, along with the foam used on Zenith PC's, turning into a tarry goo. On the CDC drives I just picked up, the entire inside of them is covered in this foam, some of it is starting to come off, or has stuck to cables and such inside. A couple smaller chunks of it literally fell off one part of the cover, the glue only holding the particular particles of the foam to which it was attached, and the rest of the foam falling away. What is the best thing to do about this, especially in something as sensitive as a disk drive? Should I remove it? What's the best method? Is there something I can use to replace it? Also, for instance, inside the cover of the PDP-11/84, there is a thin slab of foam that has turned to crud. I plan on removing this entirely - vacuuming away what I can and cleaning the rest off with something - what will dissolve this? I know that trying to get the gunk >from IBM foam off your hands is nearly impossible. Any ideas? Thanks! -Ian

Mentec

by RodSmallwood＠mail.ediconsulting.co.uk

Well that's interesting... It would seem that as long as Mentec choose to ignore non-commercial use you can do (within reason) what you like. I did say pdp preserver as opposed to RT, RSX or RSTS preserver. However I must admit to having worked in digital SWS and to having been part of the VMS marketing group I do have an interest in the software side. DEC were quite keen on educational computing and that's how they would have viewed a hobbyist program. As HP now effectivly own what was DEC I assume the agreement is now between them and Mentec. It seems that many efforts to set up a hobbyist (or collectors program) have come to nought due to Mentec seeing no profit in the arrangement. Needless to say as a DEC hardware collector a simulator is of no interest to me.

And while I have had contact with and used a bit of RSX-11 and a very extensive amount of RSTS/E, I was never responsible of a system which ran RSX-11 or RSTS/E. Which is the primary reason that I never became proficient enough to maintain either an RSX-11 or a RSTS/E system. On the other hand, I may now know RT-11 as well as some of the top RT-11 developers knew RT-11 during the 1980s. As for why Mentec no longer actively supports any of the PDP-11 systems, I venture to guess that it is no longer profitable. >As I am in the middle of restoring some pdp-11/94's the issue around >how >RT11 and RSX could be made available is of much interest. If they have >not sold the rights and are not pursuing the business perhaps they >could help us poor pdp preservers. > Mentec has helped the poor PDP-11 preservers. Unfortunately, it is not obvious since the help is more in not causing those poor PDP-11 preservers any difficulties as opposed to being proactive by making the operating systems generally available such as Borland products are at present. Also an example is the VMS hobby program which Mentec does not have. In addition, as others have mentioned in their replies, it seems very doubtful that Mentec really did "totally own" the PDP-11 operating systems. Unfortunately, it seems highly probable that the terms of the agreement between Mentec and DEC required the parties to maintain confidentiality since I can't see why those terms have never been publicly disclosed - unless those terms were so detrimental to the users that neither party wanted to admit the mistakes in the lack of a PDP-11 hobby program in the face of the VMS hobby license program. But what did happen did, what did not happen did not - the stories and interpretations that many of us make up about what happened are probably 90% fiction and are no longer even important. BUT, Mentec did make older versions of the operating systems available for legal non-commercial use under what was at the time a DEC owned emulator. It certainly seemed questionable at the time and it may be even more questionable at present, but Mentec has chosen to make no challenge to the use of those older versions of the operating systems under the current name of that DEC emulator which has evolved to become SIMH. In addition, Mentec also seems to be ignoring the legal requirement for a transfer of any operating system license to the new owner of any old PDP-11 hardware so long as, at least as far I can interpret, the new owner is non-commercial. Certainly there have been numerous discussions on classiccmp (one is going on right now about a single RL02 system) over PDP-11 use of the RT-11 operating system (i.e. NOT under SIMH) and I can't remember any recent protests from Mentec in this regard. Any finally, while the RSX-11 and RSTS/E operating systems are much more tightly controlled and not very easily available, almost 10 years ago, Megan Gentry, a former RT-11 developer, put a zip file of V05.03 of RT-11 up for general download with the explicit permission of the individuals who had to provide that permission. V05.03 of RT-11 is the last binary distribution allowed under the DEC emulator and by inference under SIMH. There is also a CD version (an ISO file) which contains as many as possible of the RT-11 binary versions as could reasonably be found for all of V05.03 of RT-11 and prior. Any for those individuals who are legally licensed to run the latest version of RT-11, V05.07 released in October of 1998 or just under 9 years ago, there is also a CD containing the rest of the RT-11 binary distributions. The latter CD was requested by a university who was legally licensed to use and already had a copy of V05.07 of RT-11 and was legally entitled to a backup of all of the RT-11 binary distributions. So - I don't really think that there are any "poor pdp preservers" as far as RT-11 is concerned. In point of fact, I have personally found ABSOLUTELY NO INTEREST in the last 5 years in: (a) Preserving RT-11, (b) Fixing any bugs in RT-11 (c) Making any enhancements in RT-11 Of course, for individuals in the know, most of them already have sufficiently preserved what they want of RT-11. On the other hand, even though I have made a number of vital bug fixes to RT-11 (for problems that crash RT-11) along with other minor problems as well as some extensive enhancements, I have yet to find anyone who is even interested in a Y3K for RT-11, let alone someone who would be interested in participating. Of course, Y3K may already have been done, the enhancements that I have already completed may have been duplicated along with many other enhancements and the bugs fixed as well and distributed to the users of RT-11. Perhaps I just don't know that it has all occurred without a word of it reaching my eyes and ears. But, as a result, I have place (a), (b) and (c) into a lower priority and focused on attempting something even less useful, i.e. confirming the value of pi(10^18) using a sieve program running under RT-11 with a view to attempting to determine pi(10^24). When I find that it will take a million years to finish the calculations for pi(10^24) with current computers, I may shift back to (a), (b) and (c) if I can't find something even less useful than knowing the value for pi(10^24). On the other hand, if anyone is really interested, drop me a line. If anyone really knows why Mentec does not have a hobby program for PDP-11 operating systems, let us know. Just don't complain about RT-11 and Mentec since nothing that Mentec seems to be doing at present interferes with "poor pdp preservers" as far as RT-11 is concerned. In 16 more years, which will be 25 years after V05.07 of RT-11 was released, I very seriously doubt that Mentec will care if every hobby user who wants a copy of V05.07 of RT-11 is using it on real DEC hardware, let alone if there is a running emulator on what goes for a PC in the year 2023 when I will be 84 years old if I am still kicking. As for commercial sites still running RT-11, if they don't already have the Y2K compliant V05.07 of RT-11, then I very much doubt that they will require V05.07 in the year 2023. And if those commercial sites are managing with the current bugs in RT-11 9 years after V05.07 was released, well ...

I found the problem with my PCW8256--it's an open "IC protector", part ICP-N75. Rated at 2.7A. Am I safe in replacing it with a far- easier-to-find-here-in-the-USA 3A picofuse? "IC protectors" must be an across-the-pond thing--I've never seen one of these before-- what are they, other than a fuse? Cheers, Chuck

In my experience, it's much easier to find an old 10baseT hub with a 10base2 port or an AUI (to which you add a 10base2 transceiver) than a 10base2 to 10baseT media converter, but the media converter will be smaller if you can track one down. -ethan

Upgrading my HP9816

by ard＠p850ug1.demon.co.uk

I've just upgraded my HP9816 (aka HP9000/216) to have 1M RAM on the processor board,. In case anyone else has one of these machines, and wants to do the upgrade, here's how I did it. -tony Upgrading an HP9816 to 1M RAM on the processor board ---------------------------------------------------- These instructions assume you're starting with a 256K processor board, that is one with 32 4164 DRAMs fitted. Firslty remove the processor board. To do this, disconnect all cables >from the rear of the 9816, then remove the DIO slot cover plate (or a DIO board witu an external connector). Remove any DIO boards in the slots -- memory voards will need to have their addresses chaged after this modification. Release the 2 quarter-turn fasteners on the rear of the machine and free the top cover from the clips under the back edge of the machine. Slide the cover rearwards, lift it off, and unplug the fan cable >from the monitor PCB. Pull the processor board -- at the very bottom of the machine -- rearwards, unclip the earth wire fromthe faston tab on the RS232 connector. Slide the processor board all the way out. Now to upgrade the RAM. Desolder all 32 DRAMs from the board. These are in 2 rows at the very front edge. Leave the clock oscillator can, reset-circuit transsitor array, and resistor pack in place. Clear out the pads for U122 (to the right of the rear row of DRAMs) and R47 (leftmost resistor in the block of 3 resisotrs to the left of the ROMs) At this stage both of those locations should be empty. Fit 32 41256 (256K*1) DRAMs in place of the 64K ones that were just removed. Fit a 74F158 at U122 and a 33 Ohm resistor at R47 Cut J11 and J12 (in front of the DIP switch array). Cut J8 1-2 and link 2-3 (this likn is in fornt of U34, near the ROMs). Turn off all sections of SW3 (frontmost DIP switch). Sections 5-7 _must_ be off or the RMA will be diabled, sections 1-4 set the address of the RAM. It's simplest to have them all off, which makes the processor board RAM appear at the top of the memory map, then to address all other boards following the HP instructions, regarding the processor board RAM as a 1M board set to '0'. Refit the processor board, conencting the ground wire. Plug in the mains cable and power up. The screen should report a little under 1M free. If all appeears to be working, switch the unit off, unplug the mains cable, and refit the covers, DIO board(s) and cables.

10base-2 to 10base-t media convertor?

Ooops missed out a step! The cheap hub with the BNC is 10Mbit but its connected to another hub that is a switch ie does both 10Mbits and 100Mbits.

Modifying a Nubus TokenRing card

by teoz＠neo.rr.com

I have 2 of these Asante MacRing (same as TokenRing I hope) NB 16/4 Nubus tokenring cards: http://home.neo.rr.com/unknownk/images/100_1106.jpg Can I solder in some parts (lower right of the card) and use rj45 to connect this card to a TokenRing Hub (when I snag one)? Seems like I need a RJ45 jack, 4 capacitors (same as the ones on the 9 pin jack above?) and a chip marked 78Z003 (what is that exactly)? Oh, does anybody have drivers for this card?

Dayton and RL02's

by charlesmorris＠hughes.net

The following thoughts have just occurred to me: 1) I am going to Dayton next week; 2) I will be driving my car alone, so can haul moderately sized pieces of equipment back home; 3) I have decided to purchase another RL02 drive and disk pack for my 11/23+ (ref. the previous single-RL02-system discussion, this seems to be a good solution to my backup problem). SO - is anyone else going to Dayton who has an RL02 for sale and can haul it there? Please contact me off-list. thanks Charles

PCW 8256 PSU questions

by cclist＠sydex.com

I got the Amstrad PCW8256 yesterday and plunked a CF diskette into it The disk spun and then the screen went dark (no beeps). I pulled my screwdriver out and opened it up. If I disconnect the CPU and check the voltages, I find that the +24v is present, but the +12 reads about 2.5v and the +5 is 0v. I'm not eager to do much with the unit, but I thought I'd give repair a shot before consigning it to the "scavenge and dump" pile. Does anyone have any ideas on what might be wrong or (gasp) even a schematic of the monitor/PSU board? I got the PCW for the disk drive, which, with a new belt appears to work just fine on a PC. Cheers, Chuck

Oddball DC-xxx tape drive

by cclist＠sydex.com

I've got a DC-300-footprint tape drive in my collection of peripherals, circa 1986 (chip dates) for which I'm trying to identify the medium. A DC-300/600 cart fits perfectly and is spun a bit by the drive before the error light comes on. Upon close examination of the drive internals, the surprise is that it doesn't use an optical sensor to determine BOT/EOT, but rather contacts on either side of the read/write head that apparently make contact with a conductive metallic strip on the tape. So the medium isn't DC300, anyone know what it is? The interface is a 50-conductor one, with unit selects from 0-3, but it doesn't seem to be QIC-02 or QIC-36--and it's not SCSI either. The drive has a motherboard with two cards in it--one appears to contain the read/write amplifiers, the other contains a 6803, 6522 and a 6821 and a 2716 EPROM with a 3M copyright sticker. The manufacturer is ADIC, but I'm unable to come up with any documentation on the web for this beast. Cheers, Chuck

The foam also tends to eat away other stuff like paint etc. so it needs removing. Get rid of as much as you can manually, by vacuuming, picking it out with tweezers from small spaces, scraping etc, then clean the remaining gunk away with alcohol (ethanol) which dissolves it instantly. Take care with plastic surfaces, they may be fogged by the alcohol. For classic cameras, new, better foam is available to replace the old stuff. I have no idea of the price or where to get it from, try asking Jon Goodman (jon_goodman at yahoo.com) who sells it in kits to reseal old cameras.

Dayton, approaching fast

by marvin＠west.net

If anyone knows the spaces where they will be selling (parking), post it here and we can go and harass each other :). My guess is we won't know until the week before. Last year, Patrick Finnigan (sp?) was there and down about 100 yards >from where I was. I got a chance to meet a number of others on this list and it is really great to put names with faces! If possible, why not plan a dinner get-together on Saturday night for the ClassicCmp group! Anyone interested? I'll be there too in an easy to recognize blue Mazda van ... it has a set of piano keys on each side and back of the van along with "Schwendtner Piano Service". If anyone is into foxhunting, I've been asked to say a few words at that forum so that will be fun. I'm also planning on trying to get an informal transmitter hunting dinner going for Friday night. If anyone here is blind or sight impaired, there will be a blind ARDF event on Sunday ... see http://www.ardfusa.com for details ... and I'll be there too with a friend who will be competing. FYI, I called the Days Inn in Miamisburg earlier this week to make reservations and they still had rooms available ... didn't ask how much :), and it is only about 5 miles or so from Hara (as I recall.)

For the ink jet printers, beware that when they clean their print heads, some models dump the excess ink into this foam or into something like blotting paper. The older and larger models have an excess ink bottle, and after many many hours operation they will ask you to empty that bottle. Usually this is based on a calculation of how much ink is there, rather than a level sensor, so if you tell the printer you have emptied it, but haven't actually done it, it will eventually overflow and make a real mess of you carpet. Some small printers so the same calculation of when the foam/blotting paper is fully saturated and ask you to change it.

Mentec

by RodSmallwood＠mail.ediconsulting.co.uk

Hi All I'm a bit confused about this Mentec issue. They bought up the rights to the pdp-11 line and even produced some new boards. Now they seem to have abandoned the whole thing. I can only find one web site that could be theirs but it is very up market corporate image stuff. No mention of pdp anything. As I am in the middle of restoring some pdp-11/94's the issue around how RT11 and RSX could be made available is of much interest. If they have not sold the rights and are not pursuing the business perhaps they could help us poor pdp preservers. Rod

Thanks! -Ian -------------------------------------- Billy responds: The foam was originally for acoustic dampening. It was a dense foam without much memory. Over time it does break down into a hideous mess. The original life of the foam was specified at 5 years! I've not had much luck taking in off with the modern solvents. This is one of the times I really miss Trichloroethylene. It would really clean this stuff up. I've used GooGone with some luck. Let it soak and it peels away. There is usually a thin clear plastic film between the glue and the foam. The more stubborn glues sometimes respond to acetone. Try a really diluted type first, say fingernail polish remover, to see that it doesn't remove the paint too. There are several options to clean up a panel. 1. The easiest is clean up as much as you can and glue a new sheet of foam over the mess. You should be able to buy panels of acoustic foam in hardware stores. 2. Remove it and leave it off. But it is lots of work to get it all off. 3. Do the best clean up you can and then spray paint with a thick rubberized paint. This seals the crumbling foam and holds it place. No matter what you do, you are in for a messy stinky time. When the foam breaks down, it goes everywhere. Be sure to vacuum every place you can. Where it won't come out with a vacuum, use air pressure to blow it out - done outside the house of course. Good luck. Billy

CDC 9775 (BZ7Ex) hard drive manual sought

by ian_primus＠yahoo.com

I've recently accquired a CDC 9775 hard drive. (675mb fixed media) It's going to need some cleaning to get it running, and I need to know some info on how to set it up. Most importantly, the heads are locked, and according to a warning note taped to the HDA, so is the spindle. I want to find out how to _properly_ do this. Unlocking the heads looks simple, but I don't see a spindle lock anywhere. Also, this drive doesn't use the typical little plugs to change the ID, so I am not sure how it is set. Bitsavers has the operator's manual, but I really need the service manual, or at least the installation manual. Thanks! -Ian

I have an Emulex Peformance 4000 Terminal Server I got at auction. It came without software, and initial inquiries some time back indicated that the software needed to be purchased from Emulex. Recently I inquired again of Emulex regarding this, and was informed that all Terminal/communications servers had been end of lifed, and was given details on where to download the Performance 4000 software. Thought this might be of interest to others out there who might have one of these stuck on a shelf somewhere. I have the boot file if you don't want to have to get it from Emulex.

In one trip using my '72 Toyota pickup. For laughs I had it weighed and it was 1204 pounds of hardware in a half ton pickup. It was full and it took hours to load it and more hours to unload it plus the 420 mile round trip. Did it twice as that was only part of the haul. However the best move I was part of was a bunch of DEC System20s fortunately the people organizing that move had a 16ft truck and access to all the loading platforms and dollys needed. Very heavy stuff and requires a bit of foreknowledge to move. Those little details like seperating cabinets and raising the feet so the casters roll and the like. The last really big move I was involved with was helping Megan move a bunch of larger PDP11 and PDP8 systems from a home to her storage. A liftgate truck made that possible. Allison

dec & vax stuff found....mostly manuals.... most of this is available

by jwest＠classiccmp.org

Below is a list of stuff I got in the mail today. Someone didn't want it to get thrown away and I offered to pay shipping costs to get it in to collectors hands. Little did I know it was going to be $150. So I'm definitely entertaining offers on any of the items below to recoup my costs. I also just want to make sure this stuff gets to collectors. Condition - most of this stuff is in unusually good condition. Many of the dec handbooks look almost new. I probably want to keep the 11/34 printset and the unibus extender. With regards to the manuals, there are some real gems in the list - note the GT40 manuals, the 11/70 handbook, and the 68000 programming card. Let me know if there is interest.

Unix disk copy using dd?

The difference between the original disk and the new disk is unused space, but you can run the host partitioner and change that (or, if it's a newer filesystem like XFS, JFS, etc. you can extend onto the unused space). P.S. - realized that my new system for replying to a digest left several messages quite probably without any subject. My apologies. Scott

I'll answer this, since several people were kind enough to patiently explain it to me when I asked the same (VFAQ, but nothing listed in one place). Mentec is still around, although it looks like the PDP-11 division website is not up right now. They did make RT-11, RSX-11, and RSTS/E available for people to use in a _non-commercial_ environment under SIMH. Images for RT-11 and RSTS/E (which does have DCL now, I was operating under old information) are available from the SIMH website. I'm not sure if the RSTS/E distribution includes the RSX runtime or not. Sadly for hobbyists, the license does not extend to true hardware, only the SIMH emulator. It seems that Mentec was looking to have an expanded hobbyist program, but it was not economically viable and/or the attitude of some hobbyists was a bit off-putting. No official reason was given, but the rumors are as above. :(. 2.11BSD and v7 are available freely, though. I believe I have gotten this correct. Scott

System 6 runs on almost all II series Macs (not on IIvx/vi, though- but those are rare). The IIci is quite common, which is why I suggested it (also 32-bit-clean if you should want to run System 7) (but you could use II, IIx, IIcx, SE/30, IIsi, IIfx also).
