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

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.

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.

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.

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

On this issue, I have to agree with Sam. I mean, personal issues are not what we're talking about here. This is the ClassicCmp mailing list, there's an entire alt.psychology section of Usenet. Use it for personal issues/problems. Also, private messages are PRIVATE. If they were meant for the group to read, then they should have been sent there in the first place. Only publisize messages when it's ABSOLUTELY NECESSARY. >Have some fucken integrity. This is what I disagree with. We're all reasonable. Now, you're going to complain about all of us being toddlers, but before you do, think of this. There are impressionalbe children on this list, myself being one of them. If you have a problem, treat it like a gentleman. We're all civilized enough to let people have their say. Make opinions pleasant for everyone to read.

my objection to recent postings

by adavie＠mad.scientist.com

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. Keep the For Sale mail, but how about labeling it with the "FS:" prefix in the subject so those who object can filter it out?

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.

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

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
