There is a series 4 also in the intel MDS line (4XX). I alway thought the MDS 800 was the first series. They didn't use the series numbers then. The ones with the monitors were not plain 800s but 2XXs. A 2XX could be a series III also. I have an original 800 box with no cards installed and a friend has a series II with a bad Ball monitor.

HP rumor(OT)

by mmcfadden＠cmh.edu

I saw a piece in the inquirer that HP may spin of the printing division and name it HP, the retained part will have some "other computer name". Maybe they want to get out of the computer business. Maybe somebody will pick up the old DEC portion and revive it. We can only hope. http://www.theinquirer.net/?article=19297 Mike

OT! Re: West meets East

by marvin＠rain.org

First, last, and only comment: The idea of "I have a plan" is like a$$holes, everyone has one. Second, ANYONE who starts off a campaign putting down their opponent as the major theme of their campaign has *no* business running or winning that office. I would have a lot more repect for Kerry if he had promoted what he thought was best for the country instead of just attacking Bush. And of course, the media makes more money by promoting this garbage. > Who would you rather have as President? > > a) Michael Sokolov > b) Michael Moore > c) Britney Spears > d) the current jackass > > Let's see how off-topic this takes us :) > > -- > > Sellam Ismail

Hi Jeff, This is an device programming adapter which looks like it might fit my Data I/O 29B. I haven't looked up the individual sockets to see what devices they are for, so I don't know if this would do anything my multipak won't already do, however I would be interested in playing with it - what do you want for it?

HP's obtained

by jwest＠classiccmp.org

Looks like I won two of the gov. liquidation auctions, and just purchased nine of the HP 21MX M-series cpu's. I'm keeping a few, the others are already destined for collectors on the list. Guess maybe someday I should get an F series to round out the product line :) Did anyone here win the other lot with 8 cpu's? Jay PS - my comparison of Britney to DEC was not intended as a slam to DEC. I happen to adore Britney (looks, not music), but monroe was a classier package :) As to the choices for president, I'll take sellams "d" choice :)

Cromemco Rescue

by marvin＠rain.org

I was contacted a couple of weeks ago by someone moving and needing to get rid of their old computers; one of them was a Cromemco Series 3 with two 8" floppies and some misc. discs. Besides the System 3, it also included the computer desk that came with the unit! We finally managed to make contact this past weekend, and it is one neat system! I have the System 3 with a HD, but the floppies only and the desk are *neat* additions to the collection!!! Also, does anyone know if the Cromemco will read the Polymorphic 8" disks? It will probably be after VCF that I will have a chance to play with it and find out, but I am really curious.

I believe Joe is correct that one can run a 8086 in the MDS800 as well as any of them. I have never seen a MDS800 in anything other than blue. I've seen a white Series II but I don't know if they were from any specific time period. All the ones we used internally were blue. I believe I saw a gray one as well. Two things were problems with the Series II machines. The early ones did not have shielding and metal coating in the keyboard case. These were very succeptable to static discharge from the operator. The Series II IOC board had a slow serial rate.

I concur with Joe, there never was a series I. The mds800 was the first development system (not counting the Intellec 8). What Siemens did though was contract with Intel to produce a "Siemens" development system which was of course just a different color Series II machine. They were off white and carried the Siemens logo. -----Original Message----- From: "Joe R." <rigdonj(a)cfl.rr.com> AFIK all of the MDS2xxs (including the blue ones) are series II machines. I've never heard of anything that Intel designated as a Series I. Most of the Series II machines have blue cases but some of them have white cases. The white ones are thought to be later machines but no one knows for sure. Just to further confuse the issue, ANY of the MDS2xxs can be upgraded to series III by adding a 8086 Resident Processor Card. I believe the MDS800s can also be upgraded to Series III the same way.

new find: an Intel MDS 800

by melamy＠earthlink.net

as for the DC37 on the back (yes, they do consider it a d-sub style connector). The more important question is what the two bottom cards are in the card cage. They are normally a two board disk controller from Intel (bit slice processor). As long as the controller was made by Intel, then the DC37 pinout should be compatible with this hardware or Intel's. I seem to recall a company called Zendex that made compatible items for the MDS series. Intel made a MDS220 and a MDS230. In either one, you could make a choice as to the density of the internal drive. As I said before, if there is a 50 pin ribbon cable between the back board (IOC) and the drive, then it is wired for SD. If an internal cable comes from the front to the disk drive, then it is wired as DD. I have both types of cables at home... About your comment on monitor troubleshooting. I have the schematic set for the Ball Brothers monitor that was usually used in the MDS2XX series. The nice thing about the monitor is that it is very simple. There is no fancy monitor control chip in it, in fact it doesn't even have any chips on it if I recall correctly. The monitor was usually supplied by Ball Brothers or Zenith. The back IOC supplies +12V poower, vertical, horizontal, and video intensity signals for display. By the way, the top card with all the switches on it is the CPU card. There were three versions of it that I know of. The first was 8080 based and only had 32K on it. I believe the remaining two versions were 8085 based with the first having 32K and the final one having 64K. If you only have 16 ram chips on your cpu board, then the next card down would or should be a 32K ram card. best regards, Steve Thatcher (one of the other MDS guys) -----Original Message----- From: Scott Stevens <chenmel(a)earthlink.net> > >The internal drive could be either SD or DD.

I suspect the system may have had something third-party added to support the two external drives, and some of the disks are labeled to indicate they are 'higher' density than the internal drive will support.

Hi Scott First, make sure you can find a replacement device and then wiggle or squeeze the lead a little with some needle nose. If it crushes or fails, replace the chip.

I wrote some code in both assembler and PL/M. Both the Series II and the 800's could run the same software. Of course, if the software was for a '86 processor, you'd need a board with that on it. When looking at the boards, don't confuse the IOC board with the main processor for the system. The IOC board has a 8085 on it but it only runs the various I/O functions. The main processor will be one of the cards on the multi-buss slots. The main processor could have been a 8080, 8085 or a 8086. This all depends on what it came with. I have both a Series II and a MDS800 at home but I've not found time to play with them. I can only play with one at a time. They are on my list to play with. I have a number of disk ( about 60-80 someplace ) and a pile of documents. I still need to catalog what I have but not gotten to it. One thing that would be great, would be to find the bits and pieces that make up the user library. There was a lot of good stuff there. I have some listing from the library and may have information on disk as well but like I say, I just haven't gotten to them yet. Also, Joe, I think I have an extra Series II keyboard. Since I've not had a chance to check things out, I may only have one working unit. Still, these are really good keyboards and are not likely to have problems. They use the hall effect switches so there is no mechanical problems other than the springs. Dwight

access to BIOS of DECpc

Hi Dave, I *was* looking for OnTrack Disk Manager. The manufacturer specific versions only work when they detect a drive of their own brand, otherwise the software simply stops. I found on the Internet the OnTrack version for IBM, Fujitsu, MicroScience and Western Digital. The drive I tried to "manage" is from HP ... I received from Pete an OnTrack version (original) which works with *all* disks ... I won the auction on eBay so in a few days/weeks I'll have the original documentation/manual too. I can scan the manual if anybody is interested. The version from eBay is 7.0? Contact off-list if anybody is interested (gooiAToceDOTnl). I appreciate your work, Dave, but the disk already runs perfectly. thanks anyway, - Henk, PA8PDP. > -----Original Message----- > From: cctalk-bounces(a)classiccmp.org > [mailto:cctalk-bounces@classiccmp.org]On Behalf Of David Woyciesjes > Sent: woensdag 27 oktober 2004 15:39 > To: On-Topic and Off-Topic Posts > Subject: Re: access to BIOS of DECpc > > > Well I finally found the disk manager floppies I was > thinking of... > Ontrack DiskManager v.2.4 dated 6/12/98 (mfg. for IBM) > Ontrack DiskManager v.? dated 1/8/99 (my note says something > about Quantum?) > Western Digital EZ Drive v.8.01W dated 1995 - 1996 > > ...of course, I don't have the e-mail address of who was looking for > them.

A short update on my efforts ... The Fujitsu-OnRack version did what was to be expected: it checks and sees that there is no Fujitsu drive in the PC and stops :-) Sorry to say that the version from Pete is for Western Digital drives and shows the same behaviour :-( I found a gfew manufacturer versions, but not for HP &%$#@!& However, there is till hope at 2 fronts: the version Dave will dig up, and there is one on auction at eBay (for just a few $$). If I will be the lucky winner I will share the data on the disk with everybody that is interested in a copy.

more good auction finds.

by tponsford＠theriver.com

Some more good auction finds: Well, the IBM s/390 in good working condition (it was a generation 3, not 4) went for $125.00. The whole row of IBM stuff went for around $800. I thought the s/390 cabinet might be useful as a walk-in closet though :-) I consoled myself with a LS ADM3A beehive terminal with the lower-case rom (works great, no burn-in, excellent condition ) for $5.00 and a couple more alpha's..spent arount $15.00 Yesterday, I picked up another alphaserver 2100, mainly for parts, although it works pefectly, it only has 1 275mhz proc and 1 128MB ram board, a coupla fddi controllers and 4-5 disks; 26z,28z,29z. and a single power supply I got three of these beasts now..I'm sorry, it's a bad habit. A big pallet of miscellaneous stuff for around $7.50 that include quite a few dec cables, a decserver 90M, two cartons of new Exatape 170m AME 8mm tapes, (unfortunatley I only have a sun EL820 7/14GB tape drive) whole bunch of office stuff and a couple more dec fddi cards and cables and a 56k pci modem, along with a huge amount of 4-pin <--> rj45 serial cables. The real find though was an complete, (monitor,keyboard,cable) apparently non-working, Digital Professional 350. On inspection, it has a 000042 CTI-bus card, which is a CTI DECNA ethernet card...woohoo. Spent around 30 dollars for everything. Cheers Tom -- --- Please do not read this sig.

new find: an Intel MDS 800

by melamy＠earthlink.net

the 8085/32K thing could be a memory issue (mine...). I have three different cpu cards and will take a "better" look at them tonight. I probably got my processors crossed... -----Original Message----- From: Dave Mabry <dmabry(a)mich.com> Steve, I never heard of an 8085-based cpu card for the Series II with only 32K of ram. Are you sure about that version? I'd bet that was not an option. I have several of both 8080- and 8085-based cpu cards.

VUPS measuring utility

CDP 1861 Video Processor

by JMeyer101＠aol.com

I am trying to get a RCA Cosmac VIP up and running, but I have two problems. I'm not familiar with the connector that this computer uses for the display and don't know how to connect it to a monitor (or whatever type of display it uses). The second problem is I need to find the 1861 chip. Does anyone know of a source where I can get one of these chips? My last issue/question is verifying what type of computer I really have. The box the computer came in is for a 18S711, but then there is a hand written note saying it's actually a 18S022. How can I verify that it is indeed a 18S022? Thanks, Jeff

rack-mount Norsk Data ND100 available

by toresbe＠ifi.uio.no

Don't throw it away! :) Don't let that thing hit the dumpster! :) The ND-100 was a brilliant machine, and had an OS far from its time. I'm actually going to see one *today* and I'll get to bring some docs home, and I'll probably get a site up that will fix the scarcity of info on this machine. It has coolness, blinkenlights, and all the bells and whistles. Please, don't let that thing die! :\ Someone pick it up, I'll probably bring software to the table soon. -- Tore S Bekkedal <toresbe(a)ifi.uio.no>

That's the CaCl in it, and there's usually not much. Calcium chloride is not merely hygroscopic but deliquescent. It's "use once" -- you can't really dry it off again, effectively. If you don't mind a liquid, concentrated sulphuric acid is a more active dessicant than either silca gel or calcium chloride ;-) Phosphorus pentoxide is good too, and doesn't get wet and sticky. Pricey, though! > A silicate solution would be less reactive, I think, and if > it dried, it's almost a protectant. "Water glass" was once a > common way to extend the shelf life of eggs, as it prevented > evaporation through the shell. For a different reason, though. There's a slow double-decomposition reaction between the calcium carbonate in the shell and the sodium silicate (water glass) which leaves a layer of relatively impermeable calcium silicate on the eggshell. Sodium silicate isn't a drying agent. The drying action of silica gel (silicon dioxide) is due to adsorbtion, a purely physical (and easily reversible) process. Water molecules stick to the surface of the silica. The granules are extremely porous on a microscopic scale so they can have quite a lot of water adhering to them. -- Pete Peter Turnbull Network Manager University of York

"System Technology Associates"? SDI-ESDI adapter

by doc＠mdrconsult.com

I'm sitting on a pair of half-wide rackmount storage devices silk-screened "RA 8" and "System Technology Associates" on front. Standard buttons - Write-Protect, Fault, A, B, on the front panel and an LED readout. 3 characters, I think. There's a Control Data Corp label on top of the box, but the model label on the side is STA. Model RA8-1100. Open PSU inside, and a logic board that converts the SDI I/O to talk to 2 Maxtor XT-8760-E ESDI drives. I can't find any mention of these puppies on Google. STA is apparently still operating as an HP VAR, but their site is less than useless. So, has anybody ever seen one? Doc

Excercising vintage items - was: Commodore 8010 IEEE-488

>I'm with you in this. I like to have all my collection working (some of >it I use -- this PC is well over 10 years old, heck the linux distro I'm >running is getting towards being on-topic). I enjoy tracking down faults, >I enjoy fixing them, and I enjoy seeing how a machine was designed and >built back then. > >That said, I take some care before applying power. In fact turning it on >is one of the last things I do. Me too. First I clean out all the dead flies, mice droppings, cobwebs and whatever else may have accumulated - this usually involves some level of disassembly, which is required anyway for the next step. Then I do a detailed visual inspection, paying special attention to "power" components, looking for discolored capacitors, resistors etc. I also look for corrosion in sockets/connectors, and anything else that looks at all out of the ordinary - I spend a fair bit of time at this. I always apply initial power through a current limiter (light bulb), which also gives me a visual indication as to how much power it is drawing. If possible, I disconnect the power-supply and energize it separately, measuring voltages. If it's analog, I ramp it up through a variac, monitoring the outputs and current draw as it comes up to operating voltage. If I can't disconnect the supply, I disconnect what I can, and pull anything socketed that I would have a tough time replacing. I don't like running equipment I am not familier with chips pulled - so I do so only long enough to verify that all power rails come up right. Recheck power rails with everything connected. Once powered up, I scope the power-rails to check for excess noise, hum etc. If the equipment does not "come up", I shut it down and do another visual. Then it's on to normal circuit debugging. The above routine may vary from one piece of equipment to another, depending on it's exact characteristics... Anything you would add?

Fibre Channel?

by jfoust＠threedee.com

I recently inherited a stack of Fibre Channel gizmos made by Compaq: three x12 hubs, a tape controller, and a Storageworks modular data router. eBay prices are all over the map: some sellers trying to unload them for $1000+, but the real auctions are going for less than $50 for each box. Each slot in the hub needs an optical transceiver; these seem to sell for $10 each. Cables? Many offered, few bidders. FC hard drives? $20 each. This stuff cost a fortune not so long ago. Why is it rock-bottom now? Will it ever be attractive to hobbyists? - John

software via radio

by julesrichardsonuk＠yahoo.co.uk

Was it this list where people were recently talking about receiving software via the radio? Apparently the UK service was called Basicode - I'm just slogging my way through a pile of documentation donated to the museum to sort out the useful stuff and stumbled across an apology letter from the BBC. Seems they'd moved transmission from Radio 1 VHF to Radio 1 MW and they didn't exactly tell people in advance :-) The letter's dated 18th October 1984. Seems that the data was transmitted as part of a radio programme called 'chip shop'. Now, I'm certain I remember seeing a manual about Basicode; I just left it in the pile at the museum that I'm yet to look through as it had 'basic' in the title and so didn't look immediately interesting :-) It was with a Dragon 32 machine (which also came with a lot of software), but whether any special hardware was needed I don't know. No practical use for anything these days of course, but an interesting snippet of computing history :-) cheers Jules

If anyone is interested (looking for a few $$ not much, plus S/H.. Or a trade for something cool...), e-mail me off line. I also have at least one License to a Version 4 of Lantastic (and I can throw in an old ISA NE2000 Card compatible with it) in the box. Never used. Also for a small consideration (or something cool) and the shipping. Just looking to clear out the closet and get a couple of bucks towards upgrading my Mac G4 Tower to a faster processor.
