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.

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.

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.

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?
Regards,
Dave

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?

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 also never heard the term Series I while working there. It
was always MDS800 and Series II or III. 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. Most simply modified
the setup of the clock rate in the ROM's to get the higher serial
rate for the built in terminal.

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.

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

can also be upgraded to Series III the same way.

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)

Actually, there's an added-in non-Intel jack on the back (I think 37
pin 'D' shaped but as everybody knows, probably not a 'Dsub' due to
size) that the external dual-8" floppy enclosure plugs into. 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. The problem is that may
IC's used iron cores and the solder plate would actually
cause electrolysis and rot the core out of the lead.

Hi Scott
I used to use both the Series II's and the MDS800's as well
when I worked at Intel in the late 70's. 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.

Hello,
I saw a newsgroup posting where you mentioned having the binary images

I have many old OSes that I would be will to share with you as well, so
ask and I'll see if I have it!
Thank you,

I'll have to admit that I have a couple as well. Still,
if something broke on one, I'd not have any ill feelings
about sending it off to the recycler and making a trip

I treasure some of my other machines.

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,

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. It looks like this is an *original* OnTrack
version that works with drives of any manufacturer. It's version 7 ...
I'll report back later.
thanks for all the help,

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

Please do not read this sig. If you have read this far, please unread back to
the beginning.
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...

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.
Don't suppose anyone has a couple of INS8154 chips lying around in their
junk box do they? I've been talking to a chap trying to restore a pair
of Acorn System 1's, both of which are missing the INS8154 chips...
Didn't occur to me at the time to ask here just in case :-)

I seem to remeber there being a VUPS-measuring DCL script which I was
able to find a few years ago, which was probably mentioned on this list.
Does anyone have a copy they could send me, or point me to where I could
find it?
My attempts at using google and looking through past email have been
fruitless so far.
Thanks much,
Pat

Some people do use Classic computers for day to day business! I use
my VAXen running 4.3BSD-Quasijarus for that. So I guess you would
want to exclude me. Fine, feel free to ignore my posts. Fortunately
there are others on this list I can ask if I have a technical question
about some DEC or other quite on-topic stuff.

Hi
Maybe it should be based of if a person in their right
mind might actually use that machine for day to day business,
it should be excluded. Of course this might very from person

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
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.

Hi Steve,
I know another local collector here in Ottawa canada that has a
TRS-80 model II and does not have a keyboard - obviously a keyboard
in any condition would be highly desirable.
What are your terms for obtaining one?

Guys,
I came across an old post of your on cctalk concerning the ORION Unilab
II - I picked one of these up today at a swap meet for $1, it has the
8088/8086 POD, what I believe is a Z80 POD and several cables with pin
connectors on the ends. I'm looking for doc's and software for the unit and
was hoping one of you could help.

FYI: I have a lot of docs on Z-80 and some of the related hardware like the
real-time-clock-thingy. I haven't searched the net to see if these are
already readily availible or not. If they aren't availible on the 'net or
incomplete I will gladly scan mine in if someone is interested.

Subject: Software for Orion Unilab II??
Hello all,
As part of a recent eBay win, I acquired an Orion Instruments Unilab II. I
have cables/software for the Rockwell 65/11EAB, and am looking for
cables/software for any other processor, especially the 1802, Z-80, 8080,
8088. If anyone has software available, and cabling diagrams, please let me
know! I have complete docs available, as well as the software for the
65/11EAB... I'd also be willing to write out a cable diagram for the
65/11EAB.
Thanks!

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!

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.

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?

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?
Regards,
Dave

But you know, that would leave out alot of cool machines
that came after 1984-- 88k-based DG AViiON's, and SGI

No, it's Fibre Channel. All my FC disks are like that, too, as the
ones at work (almost all our main file storage is FC): 40-pin connector
like a truncated SC. FC is like serial SCSI.

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?

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 :-)

Your daylight savings time process seems to fail since you have so many
months when the sun doesn't come up and you are unable to use some of
the saved daylight.

I've got a box full of (4 or 5) mixed sets of TOPS
products.
At least one of each of the following:
Tops FlashTalk Card for the PC
Tops FlashTalk Adapter for the Mac
TOPS Software
Probably more than a couple of each.
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.

Al Hartman
