<The PDP11 (at least every PDP11 that I've used) addresses memory by <bytes. OK, a 16 bit word, like an instruction, does have to lie on at an <even address, but the 16 bit address that a program generates (before <translation by the MMU) addresses one of 64K _bytes_ True but, if the memory contained nothig but instructions and addresses 32KW is the limit. Only data or IO is addressed as bytes. This would seem a trivial item it makes a difference in terms of the total number of instructions in any given amount of ram. This is more important when applied to machines with I&D space where the byte addressability can be exploited for buffers and the like. <The I/O page (certainly on Unibus PDP11's) is 4 K _words_ long. Without <an MMU you have 28kW memory, 4kW I/O Some versions and OS vaiations allowed a 2KW IO space. I've run RT-11 that way. <Wit hthe MMU enabled you can have 64k Bytes (32 k Words) of memory mapped <in. In fact you generally don't map the I/O page into user processes, <since you don't want user processes accessing device registers. True but then people ahve to understand that the MMU design seperates user space from system space. <Even if you have the MMU it's a lot simpler if your program fits into 32 <kW (or 28kW if you want access to the I/O space). Otherwise you have to <do something like using a software interrupt to change the MMU to a <different mode. I tried to keep it simple. <Unless page K1-11 of my PDP11/44 printset is wrong, the PDP11/44 has 22 b <addressing. The PDP11/45 does, indeed, only have 18 bit, alas... With the exception of the 11/70 I thought most of the unibus machines were limited to 18bits, for some devices that can be a limit. My interaction with U-bus machines is limited to the 11/70 and a 11/34 all my PDP11 time is with Q-bus (11/03, falcon, 11/23, 11/23A, 11/23b, 11/73) which has sufficient enough variation to track.

< Allison, this was private email, but I figure this may be OOPs, though I did check the header as classiccmp...? < like the 11/23 and 11/73 line should run this BSD variant as < well... what I want to know is, did the kernel fit into 64K in < one segment, or did they spread the kernel across segment < bounderies? If so, how? The kernel never fit in 64kb as the pdp11 is word addressed also the MMU operates on 4kb pages. Also the top 4kbytes are IO space. So the idea of the kernel fitting in 64k is not relevent. The real question was did it fit in the 11/44 or 45 who only had 256k (18bit addresses) space. The 11/23 and later Qbus machines were Q22 (4mb address space). The larger space means more available ram that can be used without resorting to swapping (or at least less frequently). Also PDP11s come in two other flavors, those with I&D space and those without. The 11/23 and 11/34 are those without. The 44, 45, 70, 73, 83 and others have I&D which means that Instructions and Data spaces can be seperate doubling the amount of memory available. Added to that is user and system space (memory protection between processes). So it's possible for a PDP11 to actaully address four distinct areas of memory that are non-overlapping and all 64k in size. Practical considerations limit it to less than that but it's nearly so and likely they would overlap as well. < I mean, I could see overlays (in the kernel... blech!), but I < don't remember the 11 supporting long long jumps... and address < value was 16 bits, period. Still, I was never great at 11 True of all segmented address machines. The larger 256k or 4mb space is broken into pages of which up to 8 are mapped into the 16bit address space. To do a long jump what is really done is the cpu remapped the needed page into logical space and does a 16bit jump to that page. The top 4 bits determine what page register is addressed and the contents of that register is appended to the lower 12 bit to form the larger address needed to manage a 4mb space. It takes 8 MMU registers and uses the content of the reg plus the 16bit address to form an address in physical space. < assembly. Could someone here give a good detailed account of < PDP-11 segment mapping support? Could my stack and register < values be retained and follow while moving from segment to < segment? And how the hell did you tell the memory manager you < wanted to pop to another segment, anyway? yes! A detailed discussion would wear out my fingers typing it. Sufficient that it was able to address more than 64k and while different than the 8088 or 286 in both cases the 16 bit address space was extended by argumenting the basic addressing and not extending the basic register set. I'm currently building a system using the z80 cousin called the z280 that can address 16mb of ram and the basic addressing is still 64k argumented by a MMU. Allison

This would have been before ethernet was turned > into a 'standard.' One guy I know has one of these hanging That is a DMC-11. It was an early networking card before Ethernet. It was point to point, 4 wire coax, synchronous serial at something around 1.5Mbps. The DMC-11 had an onboard bit slice processor (might have been a Signetics 8X305, not sure) to handle the packet assembly/disassembly. BTW the KMC-11 was a generic DMC-11 that was user programmable, if you wanted to roll your own protocols. I used a pair of DMC-11s in 1977 to network two PDP-11/34s with an early version of DECnet. I don't recall that DEC had any multi-drop type network interface at that time, except maybe for X.25 PADs.

< Alright, so what we have is the last 4KW used up for stack < space, register mapping, and IO mapping. I would guess the and also boot proms. Default boot on PDP11 is 173000Q. The first page is where all the vectors for the interrupts and traps are. < MMU... do I have it right? Even on a machine with a full < 22bits of address lines on the backplane, like an 11/73, the < CPU still only has a 16bit address space. The faq doesn't make < it terribly clear what happens if you want to open up any < arbitrary window. Think of the 4mb (q22) as linear physical space. At any time the CPU/MMU can allocate contigious or scattered blocks of that space as logical physical space. To do a "long jump" a local jump to a system space is done, memory management code is run and then a jump to the now available code (in logical space) is done. One of the background jobs would be to swap out old segments that are unused to make room for current processes and swap them back if the non current process should wake up. The cpu is always in logical 16bit space but the windows (multiple) can be moved around. An ascii graphic would show the CPU 16bit space as several blocks mapped to multiple blocks scattered in a larger space. The cpu literally never leaves the range of a 16bit space but instead trade out chunks of it for different ones out of an available pool. You never actually jump put of logical space only shuffle what physical memory is part of that space. Allison

Because the DDD DDD specifies a register (1 of 8) and address mode (1 of 8) to use. So, you'll often see something like JMP @#0173000, which is represented in two words 000137,173000. In this example, the address mode is 3 (auto-increment deferred, deferred = indirect) and the register to use is R7, which is the PC. So it means "jump to the address given in the word the PC points to". In other words, that's how you code an absolute jump. The reason for the auto-increment is that that mode is the general way of getting immediate data, and in the general case you do need to increment the PC after the read (think about MOV R0, @#0173000, opcode 010037,173000 which stores R0 in 173000). -- Pete Peter Turnbull Dept. of Computer Science University of York

Thoughts about a Classiccmp private newsgroup

by photze＠batelco.com.bh

Yeah, but could such a thing be done on Linux/UNIX OS's? I'm guessing that you would need a NT server... and I don't like NT servers. I actually had a NT and Linux server running on the exact same machine, at different times. NT was harder to handle, and had more crashes just when I needed it most, with many requests. Also, I had to reboot it 8 times to get it set up with my video card, but not other cards, altogether, it took 16 reboots, compared to 1 with Linux. My NT 5.0 beta is showing some signs of hope, but I'll need a lot more before trusting NT with a hobby list as important as this one. Just my 0.02 Tim D.

what is a Vax Station 2000?

by IVIE＠cc.usu.edu

> They are not CPU upgradable, but you can add expansion > memory out to 16MB, an 8 port async serial board (thats the big DB > connector that doesn't go anywhere) and a sync serial port. Sorry, the big DB that doesn't go anywhere is used to add another MFM hard disk. It contains the control and data signals for the second drive. I've not seen the 8-port option, but I believe it plugs in place of the color graphics board. > The SCSI port was only supported for the TKZ50 tape drive, an > old 95MB DLT type drive, although I think there was a 3rd party SCSI > disk driver from Trimarchi (now out of business). Gerhard Moeller (I believe that's his name) has hacked over the SCSI driver for the MicroVAX 3100 to bring it up on the 2000. I've used the driver under VMS 7.1 to speak to a tape drive (this gives me a nice little package to take on travel; a 2000 with an RD32 and a TZ30). Since it's a full-up SCSI port driver, it can be used to support anything VMS knows how to talk to; disks, tapes, etc. I've heard of one fellow who is using a 2000 to burn CDs. I suggest looking around on dejanews for discussion of Moeller's driver. > The VAXstation had a > graphics display for a non-standard monitor. All 2000s include a monochrome display built into the motherboard. It is also possible to add on a color display. Rumor has it that it is not impossible to use both displays simultaneously, but I've never tried it (my color monitors have died over the years). Roger Ivie ivie(a)cc.usu.edu

I recently acquired a Morrow Designs Pivot Model 2522 - Special, serial number 31-0001488. Both the model number and serial number are hand written on the manufacturer plate on the rear of this pc. It has dual 5 1/4 " floppy drives and 640k memory. The memory board is labelled Morrow Zenith.This is an interesting portable having a rom monitor for the built-in modem, what appears to be a built-in calculator (haven't been able to get the calculator button to do anything). Date can be changed in the monitor by pressing a button also. Boots MS-DOS fine. I read in Stan Veit's book that Zenith licensed this technology from Morrow. Does anyone have any further info on this unit or better yet a operation manual? Thanks- Marty Mintzell

Rabbit 286 ????

by rigdonj＠intellistar.net

Today I bought three portable PCs marked "Rabbit 286". They're about the size of a large lunch box and have a keyboard that fastens against one side. When you remove the keyboard it uncovers a gas plasma screen. There are slots for two 3.5 drives on the right hand side and a door on the left side. Opening the door exposes the back of several expansion card slots. There's a label on the bottom that says "Chicony Electronics Co.", "Model 286G-A", "Gas Plasma Display" and "640H x 400W Dots". One almost works, one is dead and the third one is somewhere in between. Does anyone know anything about these? I'm wondering if it's possible to put a small 386 or 486 mother board in these. Joe

You've got to be pulling my chain... (Ethernet)

by photze＠batelco.com.bh

That's exactly where I got it from. Now, I was just thinking that in 1973, that would be a huge space, the size (or larger) than hard drives! So you could transmit your entire hard drive in a second, barring server stuff and hard drive speed. It sounded strange to me. ;-) Ciao, Tim D.

eBay = Mkt Value? (was: my objection to recent postings)

I'd rather base valuations on what experienced, >knowledgeable collectors will pay. People who have a better idea of how My point too. There's a big difference in "market value" and "collector value". (Don't believe me, buy a "collectible" plate sometime, or coins >from a TV shopping channel.) Market value is what the average idiot will pay, at auction or elsewhere. Collector value is what an informed collector will pay, based on rarity, significance, etc. I've got books on disney, hot wheels/corgi/dinky/matchbox/etc., glassware, collectible board games, and so on (used to be in the business, kinda) and I am often amazed at what things sell for, at auction, at antique shows, in stores, as well as at garage sales, flea markets, and so on. Heck, Hake's is one of the biggest value setters in the US of pricing on Disney, politicals, advertising, and so on stuff, but still, a lot of collectors (me included) think their prices are inflated. Market value versus collector value. >> That's a tough call. Do you sell it to someone who will use it and >> appreciate it for what you paid for it, or do you put it on eBay so you can >> pay the property taxes? I haven't got an answer to that one yet. > >I do...sell it to me :) Ah, but... Say I'm a newbie to the group (and don't take this personally!), how do I know that if I sell you my //c LCD screen for $20, I won't see it listed on eBay next week with a starting bid of $400? And even though I know you wouldn't do that, I still not that easy. As an example, I've got two SE/30 motherboards, brand new, in the Apple Service boxes. I know some people here expressed interest in them, so I should probably offer them here, cheaply. The problem is, they're actually part of the Mac stuff allocated to my girlfriend's school. If I sold them on eBay, I might get enough to buy a complete, working IIci system to put into the classroom for the kids to use. What do I do? And even if they weren't going to the school, I wasn't able to take my dad and niece to Disneyland this year because I can't afford it. If I sold them on eBay, that would pay for part of a cheap trip to Dland. Like I said, tough call. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Re.: How about a weekly FS/T list? (was Sale postings to Classiccmp)

by rcini＠email.msn.com

Here's an idea... How about making Friday the "classifieds section" day? You know, like the local newspaper. Although classifieds appear in newspspers daily, it seems that one day has many more than the others. This would reduce the daily FS/T traffic, but still enable people to trade stuff. I see ClassicCmp as a great resource, not only for information not available elsewhere, but also for physical equipment and software which is obviously no longer made or supported by the manufacturer. I also think that those on this list should give (and be given) first crack at something that one of us has for sale. We all know eachother, have dealth with eachother previously, and for the most part, know that "the check is good." Trading should continue, but maybe it should be aggregated and done on one day. Maybe Monday's the right day...maybe Friday. I don't know. Just my $0.02. Happy Holidays to all. Rich Cini/WUGNET <nospam_rcini(a)msn.com> (remove nospam_ to use) ClubWin!

by maynard＠jmg.com

Allison, this was private email, but I figure this may be actually of interest to the group. There's nothing here personal, or insulting anyway... OK. So Allison says the HEX bus 11/44 ran a BSD variant with networking. I would guess a Q-BUS CPU with memory management like the 11/23 and 11/73 line should run this BSD variant as well... what I want to know is, did the kernel fit into 64K in one segment, or did they spread the kernel across segment bounderies? If so, how? I mean, I could see overlays (in the kernel... blech!), but I don't remember the 11 supporting long long jumps... and address value was 16 bits, period. Still, I was never great at 11 assembly. Could someone here give a good detailed account of PDP-11 segment mapping support? Could my stack and register values be retained and follow while moving from segment to segment? And how the hell did you tell the memory manager you wanted to pop to another segment, anyway? The curious want to know.... --jmg > Date: Fri, 10 Apr 1998 17:40:32 -0400 > From: allisonp(a)world.std.com (Allison J Parent) > To: maynard(a)jmg.com > Subject: Re: You've got to be pulling my chain...

[OFF TOPIC?] Fixed Freq Monitor Questions

by maynard＠jmg.com

OK, This is mildly on topic. My monitor is an HP 1097C, making it at least 10 years old. However, I am using it with a modern PC, so that's where the 'on topic' issue gets a little iffy. I'm sure there are plenty of people here who can answer this question. A pointer to a FAQ would be most welcome. These old monitors are Fixed frequency, unlike our modern monitors which multisync. The 1097C supports only a 78.125 khz Horizontal Scan Rate and a 72hz Vertical Refresh Rate. Now a couple of years ago I foolishly bought one of those cards by Mirage (www.mirage-mmc.com) which is supposed to be a 'fixed freq video card'. Actually, it's an OEM Diamond card, basically an S3/968 video processor with an IBM 52x RAMDAC - ala Diamond Stealth VRAM. The fixed Freq hacks are basically a resistor (and a jumper selection) to drive sync over green, and a homebrew PROM to skew the VESA frequencies for several video and text modes. It works, but Mirage hasn't been too helpful with getting a variety of XFree86 modelines, even though they claim to support Linux and XFree86. They give out _one_ modeline for 1280 x 1024, which they swiped from the XFree86 distribution in 'Monitors.txt'. For Windows and Dos, they give out a video driver which seems to work just fine. It will even display 320x200 full screen (Quake works great in DOS!), and boots to a functional 80x24 col text mode. How the hell do they do this? Here is how I'm calculating my video modes based in the XFree86VideoModes HOWTO (found in every Redhat 5 distribution): Dot Clock Per Second Total Horizontal Pixels Per Line = -------------------------- Horizontal Scanning Rate Since my refresh rate must be at 72hz to sync with the HP1097C: Dot Clock Refresh Rate = ------------------------------------------------- Horizontal Frame Length * Vertical Frame Length So, it's really more constructive to think of this as how many pixels _total_ do I need to display in order to get a 72 hz vertical scan rate with any arbitrary dot clock? In this case I need Dot Clock Total Pixels Per Frame (HFLxVFL) = ------------- Refresh Rate Since I know my Horizontal Pixels Per Line, I can use this to determine the number of vertical lines which will support a 72 hz refresh rate.... hmmm, this is where things get sticky. We'll start with a DCL of 10Mhz... 10Mhz Dot Clock 128 Horizontal Pixels = ----------------------------- 78125 hz Vertical Scan Rate 10 Mhz Dot Clock 138888 Total Pixels = --------------------------- 72 hz Refresh Rate 138888.88 Pixels 1085 Vertical Lines Per Frame = ----------------------- 128 Horizontal Pixels Sheesh! A (total) screen resolution of 128H x 1085V? What about a 20 Mhz dot clock? Well, after graphing the results I quickly observed this: S | T C | o R R | 128H 256H 384H 512H 640H 1728H ** T E E | x x x x x x A E S | 1085V 1085V 1085V 1085V 1085V 1085V L N | | DCL ----+------+-------+-------+-------+------- [...] ----+----- 10 20 30 40 50 135 (** Perfect for a usful screen resolution of 1280x1024) So, based on this, I cannot get small or talored screen resolutions unless I am willing to accept wide borders and strange resolutions. Yet my card works....It does _not_ display this behavior... so I suspect my thinking is to blame. Will someone please correct me? Apologies if you consider this post off topic... J. Maynard Gelinas

They > are similar in that they are both bus topology using CSMA/CD > arbitration. > Not quite. Arcnet was not a CSMA/CD but token passing, more in common with Token Ring rather than Ethernet. Arcnet used a bus, but a token was passed along to each node and that node sent a packet only when it got the token. Whenever a new node came online the rest of the nodes would reconfigure and start the token over again. Collisions only occured when new nodes came on line the first time. IIRC it was Datapoint that first came up with Arcnet for their multi-user terminals. For a small number of static nodes the Arcnet throughput was actually quite good. Whereas ethernet is probabilistic for access, token passing is deterministic in that you are guaranteed a slice of bandwidth to every node. At a minimum you always had roughly 1/n of available bandwidth, where n was the number of nodes. Arcnet degraded in a linear fashion as nodes were added, but Ethernet degradation can approach geometric rates, as anyone knows when they see that collision light on the UTP hub go on solid. Also, Arcnet was 2.5Mbps. The original version used coax (not Ethernet thinwire! I think it was RG-92?) into hubs, later versions went to twisted pair. There was a 20Mbps follow-up from SMC (the primary chip maker for Arcnet) but it never caught on. Arcnet was a common networking standard for S-100 systems in the early to mid 80s, using MP/M and CP/NET from Digital Research. I think it was one of the first network transports supported by NetWare too. Jack Peacock

Is this possible? (Storage) (Off-topic?)

by maxeskin＠hotmail.com

Sam, you have to understand that if people don't feel comfortable asking questions on this list, even if they are irrelevant, they won't ask anything at all. You can't intimidate people if you want them to deal with you. In response to the original question: the isolinear chips are supposed to be holographic memory, which is in the works, and will allow terabytes of storage in several cubic centimeters, just like on the Enterprise. The nanites have an advanced version of modern nanomachinery. I would think that .5 micron hard drives are easier in this case. As for the ancient storage, I think that was magnetic.

by Marty＠itgonline.com

Not to beat a dead horse, but I believe Tim's question was relevant. I read about optical storage using holography well over ten years ago but am unaware of its present use or status. This may not strictly qualify as classic computer subject matter but shouldn't we give a 12 year-old a break? Tim should be commended and encouraged for his interest in computer science and preservation, not hen-pecked over the fact that he related his question to a Star Trak episode. Keep asking questions Tim and don't let anybody intimidate you into silence.

eBay = Mkt Value? (was: my objection to recent postings)

At 01:07 AM 4/9/98 -0700, you wrote: >I agree. Ebay is definitely NOT indicative of "actual market value".

Someone thinking they got a great deal on a >complete C64 system for $25 got ripped off since I can pick up something >similar locally for less than $10. Well, "actual market value" is exactly what eBay is -- the value of an object (i.e., what it sells for) on the open market. Ya can't get much more open than eBay, what with it's internationalism. As to whether prices on eBay represent what experienced, knowledgeable collectors will pay, that's another story. And lastly, yes, values are determined in large part by scarcity. Here in San Francisco, a postcard with a picture of the Golden Gate Bridge will cost me 25 cents (or so). In New York, I'd probably have to pay a bit more for one, and still more if I were in, say, Ayr, Scotland. Here in the SF area, a lot of computers are readily available, and affordable. This is a very technically aware locale, and a lot of the people here were early-adopters of computer technology (unlike, say, parts of Pennsylvania that are primarily Amish.) So they'll be cheaper here than elsewhere. So people in PA can either pay higher prices there, buy over the net (including eBay), or hop a plane to SF. As a side note, it always makes me laugh when at antique shows when I see some item for sale for $15 that I know can be bought at Disneyland, brand new, for $3. But people pay those prices, because not everyone goes to DLand every year. >Ugh! Don't do that! Sell it to someone who would appreciate and >actually use it (like me! :) That's a tough call. Do you sell it to someone who will use it and appreciate it for what you paid for it, or do you put it on eBay so you can pay the property taxes?

Well, it really depends. After asking my self, I said "No." Then, after contemplating it, and asking again, I have to say "Yes."

TI 99/4a

by maxeskin＠hotmail.com

I am pretty sure that the TI itself works. I plugged in a commodore 5-pin monitor cable. The video pinouts differ, I guess, but the audio worked. It beeped when I turned it on, and booped whenever I pressed a key. I checked the modulator box cable, and it's fine. Also, the box is getting power. Still, the little led on it does not light up, and ISDN (It Still Does Nothing). ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Even if everyone could agree on this it would last for about 1 week and then go back to status quo. I really don't mind the ads. They are not excessive, they are reaching a good market where there is a win-win (the seller gets some money and space back and the buyer gets first crack at cool stuff), and they are more on topic than the drivel that has been plaguing us for the last four weeks or so.

Thoughts about a Classiccmp private newsgroup

by rcini＠email.msn.com

Scanning today''s messages gave me an idea. I don't know if this has been discussed before, but I don't remember it being discussed. It's sometimes hard to follow the list with all of the quoted-replies; maybe tracking deep-threaded messages is just not my strong suit :-) Anyway, as part of my Microsoft beta testing, I belong to a small group of "elite" testers. Called ClubWin!, we have a private administrative newsgroup that requires a login name and password. Having a ClassicCmp newsgroup would provide a threaded conversation capability. We could also hang an e-mail gateway off of the news server to provide e-mail messages for those who can't or want to use a newsgroup.

Burroughs B27?

by jfoust＠threedee.com

Ten-plus years ago, I was given an opportunity to scrap a Burroughs machine of some kind. I don't think it was still running, and it was the size of a small refrigerator. I pulled the interesting chips and disassembled the open-air hard disk unit. It was covered in a clear sheet plastic frame, sealed with snaps or Velcro, and the 14" platters spun in the air like a turntable. I still have the two platters on the wall. - John Jefferson Computer Museum <http://www.threedee.com/jcm>

A *very* valid comment. >> More seriously, has anyone here actually conducted a transaction >> through Ebay? Did the highest bidder actually make payment in >> a timely manner, if you were selling? I have both bought and sold (mostly bought, though) through eBay. Mostly Classic Computers, Donald Duck stuff, and Miniature Land Rovers. Had one problem once, when the guy ignored me for a while, then eventually claimed to have previously sold the stuff I bid on. Never had a problem with a payment. Generally, stuff is well packaged, though one time, I bought a TI99/4A in the original box, and it arrived -- in the original box, covered with duct tape. I was heartbroken. I explained to the guy that I had been interested in the box as much as the computer, and he offered to refund my money. (I didn't take him up on the offer, just wanted to prevent it from happening to someone else.) For comparison, I once ordered a Donald Duck nutcracker (new) from the Disney catalog. The 6"x6"x12" nutcracker box came in a 2'x1'x3' box, with a few sheets of tissue paper, neatly folded on the bottom of the box. I was *not* happy. The feedback system on ebay seems to work pretty well, I think. I feel pretty comfortable buying and selling there. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

Test equipment - must sell soon

by rhblake＠bbtel.com

Ive had this posted in the past but these are really getting in my way: *Tektronix 7612D programmable digitizer (scope w/o a screen) with two 7A16A plugins. No manuals or cables but it appears to be in terrific shape otherwise. $150 plus shipping or will consider trades. *Kontron KLA64 64 channel logic analyser - 2 complete units, cables, manuals, covers, software, etc. They also have an optional unit installed internally. Includes Axiom video printer. All items go as a package - $325 plus shipping. Sorry no trades and will not separate. Total weight about 160 lbs for everything. Can email detailed info to those interested. I bought these in an auction lot and the above pricing is what I have into them. I bought the auction lot to primarily obtain a digital oscilloscope for my shop but the above items are R&D oriented and realy have no use in my repair shop. Both are still supported by repair, calibration and parts outfits as well as the manufacturers. I have sources for the manual for the Tek 7612D and plugins as well so you don't need to be concerrned that you'll not be able to work it without a manual. The manuals for the Kontrons is very detailed and is from setup and use to parts and adjustment. I'm trying to be as discrete as possible about posting these and I'm sure some people are tired of seeing it come back up but there are new people to the list that may not know of them and possibly be interested. Please reply direct to me, not to the list. -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ # 1714857 * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

VMS is fairly loaded, editors, MACRO32, BASIC, DCL(the command line language is as complex as some of the 8bit basics!), various language libraries (C, Fortran, Macro). DECwindows is part of the OS as is DECnet. Also DECwindows server, latserver and software to manage the system, accounts, networks. VMS as supplied is a complete working OS and environment and anything but minimal in the pieces supplied. I've done entire network projects using nothing but DCL scripts! The first software to download for VMS is CMUip (I think the cdrom has it) so that IP connections can managed). I'm sure there are suitable C compilers in the free/shareware domain. Most people have little knowledge of what VMS is. It's a multiuser, multitasking OS designed for robust applications with high security. What isn't mentioned is it's also a user enviornment, development system and a aplications platform all rolled into one. It also has the advantage of 20 years of development history with V7.1 being current but any version between 5.4 and 6.1 covered under the hobby license. I run 5.4 and 5.5 as it's as good as any and they are all good. An advantage for the non unix user is DCL is like DOS command lines to the user and most of the basic facilities are similar though richer featured. Allison

TI99/4a

by maxeskin＠hotmail.com

Today, I found two things in the trash. One is a VCR that eats tapes. Please e-mail me privately if you know what to do about that. The other is a TI99/4A with all of the packaging, but without the main manual, and any cartridges it might have come with. I will still go back tomorrow and check to make sure I didn't leave anything. Anyway, do I HAVE to have a cartridge to power it up? When I turn it on with the enormous TV switchbox, the TV shows nothing but snow. I flip all of the switches, but none fix the problem. Also, the little light on the TV switchbox doesn't turn on. Suggestions? Also, was there a word processor or something for it? Could someone send me a cartridge or two? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

what is a Vax Station 2000?

by allisonp＠world.std.com

Hi Soe, < I went to a thrift store today and found something called a VaxStation <2000. Does anyone know what it is? I *think* the model number on it is <1410F-A. It's a box about 12 x 12" and 10" thick and has a handle on th VS2000 aka baby vax. Nice machines using the first generation micorvax chip. They can be found with up to 14mb of ram but 6-12mb are typical and only 4meg needed to run VMS or Ultrix. They can take RX33(1.2mb) floppy and or any MFM drive like RD31(20mb st225), RD32(40mb st251), RD52(quantum D540 31mb), RD53 (micropolus1325 71mb) or RD54(maxtor 2990 159mb). There is a scsi bus but the rom boot only knows an oddball tk50 off that. The base machine did hires(1280x1024) video to a 19in mono monitor and there was color too. By shorting pins 8,9 of the db9 port you could connect a terminal instead. VMS is available via hobby license and is a very robust and sophisticated operating system and will fit on a single RD54 or can be made to fit in an RD53 without decwindows. There is a fair amount of free software for VMS as well. Also most have 10b2 eithernet unless someone robbed the lance card. I have three of them, I call them a half cubic foot vax. The taller ones have a base that addes expansion connectors for a like sized box that can hone another MFM disk, floppy or TK50 tape. Generally speaking I find them for free to maybe 15$ as they are on par with slower 386s meaning they run all the VAX software but it's only .9 vups. Despite that I've used one to serve several users and notes conferences (like a newsgroup). Their upside is that the power needs are only 160w at 110v and they are small. Allison

RK05 story -- was "Re: Wirehead Update"

The head hit a 1/4 inch bulge in the disk platter Many years ago I worked in a high school that had some PDP-8s, one of which had a pair of RK05s and a collection of packs of dubious heritage. One of the parents was a DEC engineer, and volunteered to service the drives and check the packs. Two he condemned, on the grounds that using them might well damage the drive, but one in particular apparently passed his inspection, except that it rattled when it was picked up. Since this was the system pack, he was asked about this. He re-affirmed that it was OK, but agreed to open it up for a look. Out fell a Number 8 1" long woodscrew... but the pack was still worked fine. -- Pete Peter Turnbull Dept. of Computer Science University of York

what is a Vax Station 2000?

by peacock＠simconv.com

A uVAX 2000 is a single board uVAX II with onboard peripherals. DEC sold them as workstations (VAXstation 2000) or as a small server (MicroVAX 2000). They are not CPU upgradable, but you can add expansion memory out to 16MB, an 8 port async serial board (thats the big DB connector that doesn't go anywhere) and a sync serial port. Standard was the MFM interface for a Micropolis 1325 (RD53) or Maxstor 2190 disk (RD54). The SCSI port was only supported for the TKZ50 tape drive, an old 95MB DLT type drive, although I think there was a 3rd party SCSI disk driver from Trimarchi (now out of business). The VAXstation had a graphics display for a non-standard monitor.

what is a Vax Station 2000?

by rigdonj＠intellistar.net

I went to a trift store today and found something called a VaxStation 2000. Does anyone know what it is? I *think* the model number on it is VS 1410F-A. It's a box about 12 x 12" and 10" thick and has a handle on the front. It looks about like one of the small coolers that holds a six pack of your favorite refreshments. It has a bunch of connectors on the back includeing a BNC connector (LAN?) and SCSI connector and a large DB style connector with 4 rows of pin sockets.

Sale postings to classiccmp (RE: my objection to recent postings)

by kaikal＠MICROSOFT.com

Since Bill is absent, I'll presume to speak for him and the rest of us founding members. You'll notice that the name of the list, same as its charter, is "Discussion re-collecting of classic computers", not "preservation" although that is something we are all concerned with. Webster's defines "collect" in this sense as "to collect objects", which implicitly requires their acquisition! Blatantly commercial advertisements are not allowed, but collector for-sale ads are explicitly part of this newsgroup and are welcomed. Not only that, but offering items on Ebay instead of on this list, opens them up to the speculative investor masses and creates much higher prices than trading among collectors would produce. Trust me, it's much better to have them advertised here than on Ebay.

ForSale items on Classiccmp

by kyrrin＠jps.net

Andrew Davie scribed... >I object to the use of the Classic Computer mailing list for advertising >for-sale items on an ongoing basis for profit. I consider the use of this >list in this way akin to dropping advertising leaflets in my mailbox, or >ringing me up and asking if I want to buy insurance. I'm going to assume that you're referring to Russ Blakeman's posts (please forgive me if this is inaccurate), and possibly to the postings of 'classic' systems in need of rescuing. My take on this is that I'm sorry you feel that way. For my part, I'm darn glad to have someone posting to the list who seems to have a steady stream of older gear available, and pretty decent prices to boot. There's still plenty of good information to be had in the list. The few 'For Sale' postings I've seen from Russ and others (Jim Willing for another example) have, if anything, increased the value of CLASSICCMP for me. Also, as I recall, CLASSICCMP's charter allows for the posting of such blurbs as long as what's being advertised is computer-related and of 'Classic' (greater than ten years old) vintage. As for systems needing rescue, darn few people who post that they're getting rid of systems to comp.sys.dec or comp.sys.dec.micro even know this list exists. I will always forward such notes, if I happen to see them, over to the list server. I know that doing so has resulted in at least a couple of rescues that might otherwise have ended up with the scrappers. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)jps.net) "Our science can only describe an object, event, or living thing in our own human terms.

Trust me, it's much better to >have them advertised here than on Ebay. Yes, absolutely. For the first 30 seconds, it seemed like online auctions would be a great way to pick up discontinued items at a good price, but the high quality of information and easy availability drove prices up. Good for sellers, bad for cheapskate buyers. I find the online "auctions" drive prices for conventional PC stuff exactly to the average retail price, or sometimes even above that. As I wrote on 2/23: >Regarding the three Altair machines that were recently posted >to the net auction at ebay.com - they went from $1525 to $2025. >Mind you, these weren't complete systems. The software, extra >drives, etc. were auctioned separately. I was in contact with the guy who sold these before he submitted them to ebay. For a moment, I thought I had a line on a good deal: a well-off surgeon / ham / computer junk had died and his family didn't know what to do with the multiple garages of stuff. For the computers, they turned to the one computer-head nephew, who was smart enough to know the value of the machines as well as how to get the highest price - which I wholeheartedly but sadly supported. :-) Van Burnham <van(a)wired.com> wrote: >van burnham http://www.futuraworld.com >production manager >wired 520 third street fourth floor san francisco ca 94107 united >states Oh, no.

Mindset PC & Fortune 32:16

by dlw＠trailingedge.com

First the Mindset PC... I just received 2 Mindset PCs, one in the original boxes. I plan on testing the one in the original boxes and then storing it away. The other I plan on using. Here is what I know about these so far. They were 80186 based. Base unit came with 64K RAM, 32K for programs and 32K for video and 32K of ROM. It included 2 ROM/NVRAM cartridge ports up front. The expansion unit plugged into the top of the base unit and raised the RAM to 256K and added 2 360K floppy drives. In place of slots, the system has 6 cartridge ports in the back, 3 in the base and 3 in the expansion unit. Things like RS-232 ports, parallel ports, etc came in cartridges which slid into these ports. It also included a mouse. It had enhanced graphic features (for the time) driven by some special chips I believe. Connections in the back provide for RGB, Composite and TV hook-ups as well as Audio connections. And a cool graphics program called Lumena which included some animation capabilities. I understand there was some sort of genlocking capability as well. It almost appears that this was the "Amiga" of the Intel world. I'll know more after I've had a chance to do more than unpack and power up the system. I would like to know if anyone else here has one of these or any info for them. I have the Disk Operating System Manual and the Mindset Operation Guide but no real hardware refs. I'd be interested in any info on the hardware itself or software, carts, etc. Now for the Fortune 32:16... I've had two different models of these for a while now but without the Fortune terminal. These are 68000 Unix based systems and it appears that you need special keys on the terminal to cleanly startup and shutdown the system. I have been travelling and need to look into this a little better. Anyway, if anyone has one of these terminals they would like to pass on or could find out what code sequence the special keys send so I could re-program my terminals I'd really appreciate it.

Diamond D5 Wordprocessor

I seem to remember that the PSU outputs were good - at least everything was as it should be at the drive connectors. The machine's in storage about 200 miles away from me at the moment, so unfortunately I can't check (one day I will get a place with a bit of space!!!) I never stripped the machine down and rebuilt it though. >>BTW, if you don't have the key needed to open the back of the machine, >>either pick the lock (it's a trivial wafer tumbler one) or flip the >>machine sideways and unscrew the plates on the bottom. That will release >>the back cover. The rest of the case then comes off. Heh heh, yup - I remember doing exactly that... >>> There's no cursor or anything on the monitor, but having never seen the >>> machine working myself I don't know if it should display anything at all >>> before a successful boot completes. >> >>Have you got the monitor cabled up correctly? There's a 10 way (?) ribbon >>cable _and_ a mains lead to connect. The monitor is getting HT power to the tube OK, and from what I remember the ribbon cable would only plug in the back of the system unit one way round, so that should be ok. It bothers me that there's no cursor or anything on the screen, but I don't know if there should be - chances are good that what little ROM this machine has would contain just enough to boot from disk and nothing else. It's a shame that the disks I have aren't known to be good - I have 2 or 3 system disks but all of them give the same results - disk seeks and spins on power up and then all goes quiet. let me know when you get your Diamond running! :) cheers Jules

I object to the use of the Classic Computer mailing list for advertising for-sale items on an ongoing basis for profit. I consider the use of this list in this way akin to dropping advertising leaflets in my mailbox, or ringing me up and asking if I want to buy insurance. Surely, the newsgroups and eBay, etc., are an appropriate place for regular sales? A mailing list dealing with the preservation of classic computers is not. Cheers A

I don't see why defacing a classic Mac (or "Frankentosh" as > they say) should be regarded as any less horriffic. Am I totally off > here? Anyone? No, you're just mostly off. The 128K Mac in question was one that had been upgraded with contemporary modifications during its useful service life, with the intention of making it do its thing, only better. It wasn't defaced, it was enhanced, with things that were designed for just that purpose, by someone using it for its intended purpose. And at its core it's the same 128K Mac. Gutting a 128K Mac to fit an SE/30's works inside would be stretching this notion of "enhancement" a bit more than I'm comfortable with, because so far as I know Mac users didn't do that sort of thing and that sure isn't what SE/30 works were designed for. (But I'm not a Mac guy and maybe someone did do this back then.) And if I knew of someone planning to do something like what you describe to a Computer Space machine today, well...I think that stretches this notion past the point of fatigue. I'd certainly encourage him away from such a course of action. What would I have done in, say, 1982 though? I don't know, I might have even helped do it, though I really don't think I'd have seen any point to it even then. Now, that said, the goals of collectors don't necessarily have much to do with the goals of the computer's contemporary users. Original unmodified 128K Macs will probably be of more interest to some, because they were The First Macintoshes (available for public sale, anyway), and being first does have a certain cachet. And the fact that many of their original users felt the need for such upgrades has made unmodified 128K Macs that much rarer today. -Frank McConnell

Random repair pieces, odd boards, documentation, weird It seems to me if the "for sale" was restricted to 10 years or older there would be no place for spam related "hot PII price list" stuff. I have never received a single spam price list listing a uVAX I, an IMSAI chassis, or a big price break on 16KB static RAM boards.

New, unused, in the box. Includes PC and S/34/36/38 5.25 and 8" disks as well as the cable and interface unit for the PC. So there it is....The total weight of all the binders, pages, disks, disk holders, etc is roughly 50 lbs. The 5251/11 enhanced S34/36/38 set which is another 10 lbs. Can be packed in separate cartons or in one 60 lb box. One box is cheaper to ship, of course. How much? $100 plus shipping for ALL the books and 5251/11 outfit plus shipping. I've had a few serious inquiries but no definitive answer back and I need the space. I paid $90 for this stuff myself so I'm making a few bucks basically to cover my gas in running it to the shipping point and my material in packing them. I don't mind getting this stuff to redistribute to people that need it as I know this stuff is getting hard to find. Otherwise you know where it would go. First one to contact me and actually send a money order (after contact) gets them. I'll need your zip code to figure shipping fees when you contact me. -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ # 1714857 * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------

Diamond D5 Wordprocessor

by JRichardson＠softwright.co.uk

Hi All, Has anyone had any experience with a Diamond D5 wordprocessor? Has anyone even *heard* of such a beast? One was donated to me a while ago after standing unused in a garage for a few years - apparently it was working when it went into store. However, nowadays if I put the system disk into the drive it seeks the heads, spins a couple of times, then all goes silent. There's no cursor or anything on the monitor, but having never seen the machine working myself I don't know if it should display anything at all before a successful boot completes. Basically I'm after more information before I can seriously start thinking about getting this thing going. Obviously I don't even know if the system disks are still good, let alone what sort of hardware faults exist inside... thanks for *any* help with this thing!! cheers Jules

Dick Smith System 80 S-100 Expansion Connections

by Guerney＠uq.net.au

I have just bought an almost-new condition fully kitted out Dick Smith System 80 - this was an Australian-sold clone of the TRS-80. The system consists of a console with included tape player, an S-100 expansion box and two 200K 5.25" floppy drives. The receipt dated September 1982 was in one of the boxes (all original packing) along with all connectors. The expansion box contains an extra 32K RAM (total 48K) and connecting cables to the main system, the two drives (each one a separate stock item, one "Disk 0" and the other "Disk 1") and to a Centronics printer. Price asked in a charity shop was $10 each for the two big boxes and $5 each for the two drives. Not too bad, and you can't argue too much when the money is going to a good cause! But absolutely no documentation. The basic system works OK. What I want to know is how to connect up the expansion box to the main box and the drives. The connecting cables are standard flat multi-strand cable with the Pin 1 side marked in red. But which is Pin 1 at the connection blocks? I don't want to kill this beautifully clean unit by connecting it up backwards! If someone could tell me which end of each of the connection blocks on the back of the console, on the S-100 box and on the disk drives is the Pin 1 end, I would be grateful. Phil

DEC RRD-40 CD-ROM

by healyzh＠ix.netcom.com

OK, I'm stumped. What are the switch setting for the 4-switch DIP switch on the back of a RRD-40 drive? I managed to come up with a working configuration, but how safe is SCSI address 0 under VMS? I know the Hobbyist CD at least boots through the hardware search in Standalone backup (didn't have time to install tonite). Also what's the 4th switch for? Thanks, Zane | Zane H.

I'm not advocating responsibility for the user's sake. If you care about the neighbors seeing you nekkid, pull down the damn shades. The reason I advocate it is because I don't want my neighbors boarding up their windows because they don't know if pulling down the shades is enough. I don't want people trashing significant machines because they heard about someone who knew someone who had a friend who heard about someone who gave a computer to a collector, and then those quickcam pics of the wife au naturel (that he thought he deleted) ended up on the 'net. Whether or not its true, and whether or not someone has pics like that, doesn't matter. The technoidiots will trash machines rather than take any risks. Don't believe me?

Yes I remember the article (it was humor) because a friend asked if I could build the same thing for him. I think it was Popular Electronics, there were no tech details so I'm sure it wasn't BYTE or KILOBAUD. Anyway, I was skeptical that it was real so I told my friend to contact the author before I took any of his money. My friend contacted the author for details. The author admitted he had embellished the capabilities and the article was more fiction than fact, although theoretically possible to do at the time. Jack Peacock

S34 system

by allisonp＠world.std.com

I got to meet Max today and see the S34. Nice machine is fair condition. His problem is that it's wired for 208 and from what I could observe all the transformer primaries are limited to the 200V range (208/220/240). Can some one up on S34s confirm that? All the power comes from three feroresonant transformers (CVTs) which explains the 580v warning (across the resonating capacitor). It would seem the only way to power it off 117v line is tansformer of the 1000-2000va size. I suspect the smaller will work as this machine while complete is not "loaded". It's biggest disk is an internal 69mb 8" with what appears to be a DC spindle. Anyhow for power it expects a single phase 208 L-L connection so a auto transformer may do it. It's been a while since I've seens linear regulators or possibly low voltage switchers of this size. Allison
