Well Hurricane Jeanne has come and gone. This is the fourth hurricane in
6 weeks and the third that's gone through my area. The DEC and intel stuff
sitting outside STILL hasn't blown away! Not too much damage this time, for
the most part everything that could be torn up was destroyed in the
previous storms. However my roof shingles are finally starting to go. The
power companies are getting GOOD at this. This time they had the power back
on the same day! I think there's going to be lots of houses (or vacant
lots!) for sale in Florida real soon. I went to Home Depot this morning
and it was packed with people buying roofing materials and other repair
items. A lot of them also had "Home for Sale" signs in their carts!
I haven't heard from Glen. I know he was without power for five then
seven days from the two previous storms and I think he's about ready to
leave the state.

Hi,
I'll gladly admit to having one. What a wonderful old beast. Got it a few weeks ago - covered in grime and dirt, but I cleaned up the main box and all the boards and connectors and it runs like a dream now.
It's an MDS-225, and it came with the expansion chasis, double-density disk drive array, ICE-80, ICE-51 and ICE-41 emulators and software and ISIS-II disks. I ran the ROM-based diags and it all came out okay - including the integral disk drive. I need a cable (or pinouts so I can make one) to attach the disk array. I think I'll need the disk array 'cos most of the disks are double density and won't run on the integral drive.
I haven't cleaned up or attached the expansion chasis yet. I'm currently on the hunt for manuals and have got most of them from the net and printed them out. Great stuff. I love this old equipment. I'm still getting used to it 'cos I've never used a diskette-only based MDS.
My current pride and joy is an MDS-Series4 with ICE-85B emulator. I got another Series-4 also (when I got the MDS-225), but, as mentioned in a previous post, this baby's got a RAM error and I don't have enough spare 2118 chips to replace all the current chips, so I'm trying to isolate the chip, but it's kinds hard with no cct diagram. The CRO doesn't show anything wrong, but as the System Monitor comes up I think I'll write a short program to help isolate the fault.
But, as both systems cost me only $88AUD, I can't really complain - even though their bulk is a challenge to the wife as they are in the family room. I don't think she's an "old big Intel box" sorta lady. :)
Oh, thanks again to Dave for the TD images for the iPDS. I'm having a bit of fun with that thing also. Simply marvellous stuff. I got an ISIS-II users guide - thanks Fritz - so I'll be getting into this too. Ahh.. so many projects and things! I love it.

Hi all,
I got 2 Memory Boards (National semiconductor) several weeks ago (each 1MB).
Somerwhere on the net, someone says, that these can be used in VAX 11/7xx.
Can I use these boards in my PDP 11/24, too ?
I don't know yet, if 32bit boards can be used on 16bit machines and
I'm afraid of putting them in and seeing some smoke when turning on the machine...

Bob,
I've seen this work with IDE drives that wouldn't spin up due to bad
bearings.
Freeze the drive in your freezer then spin it up while it's still frozen.
This seems to free the bearings for a short time so the drive can spin up.
I know of a couple people who used this technique to copy the contents off a
dead drive, they required several freeze passes to get all the data as the
drive tends to warm up quickly once pulled from the freezer and powered up.
The speculation has been that the metal contracts when frozen and releases
stuck bearings, this has always seemed an
'Odd' explanation as the bearings and races should contract at the same rate
assuming similar materials.
Of course this is a last resort option and your experience may vary.

Surface to mass differences should allow one to cool faster, and although
both may in the end shrink to the same size, one should shrink quicker,
and the initial shrink may be all that is popping it free.
I'm not saying that is why the trick works... I'm just pointing out some
validity in the plausible nature of the idea.

Ordinary PC-type 72-pin SIMMs should be fine, but I think you need Fast
Page Mode rather than EDO. You don't need parity, but it will do no
harm if you have 36-bit SIMMs instead of 32-bit. lowendmac mentions
80ns, so 70ns or 60ns will also do. I bought 4 x 32MB SIMMs about 4
weeks ago on eBay for an SGI, which wants FPM+parity and gold contacts;
it was quite cheap (under $20). The same seller had quite a lot that
was non-parity, and he even mentioned Apples.

You are correct.. There is actually a pretty good description of which
and why here:
http://www.macgurus.com/products/motherboards/mbppc6400.php
I had forgotten about the late Alchemy designs with soldered down EDO RAM.
Hello all,
I have a Powermac 8100/80 that needs a RAM upgrade. Lowendmac.com
says that it can handle 72-pin SIMMs, up to 32MB each. My question is
this: does it take the same 72-pin SIMMs as a PC, or does it require
special "mac-only" SIMMs? Google only showed people still selling the
RAM (for outrageous prices), and I couldn't get actual specs on the
RAM itself.
Thanks for any help ....
BTW, the 8100 was introduce in early 1994, so I think I'm actually on topic! :-)
Rich B.
I've talked to the engineers at DMA Systems (removeable HD mfg that was
bought out by Ricoh?) and they indicated they would test run their
drives with no cover (in an open room, not a clean room.) The caveat was
to not be in a dusty or dirty environment. I've done what Jules mentions
and it works well! I did that on a HD just to see what would happen ...
nothing, and it worked fine for another couple of years after I put the
cover back on. There is usually a filter inside the (older?) disk drives
and I *think* it will clean out any dust that got in the drive while the
cover was off.

Not entirely accurate... although the ones I was thinking of don't use
EDO anyway (my memory told me the 660AV and 840AV required EDO memory
installed in pairs... I just looked it up and it appears I'm wrong, they
don't care).
However, there ARE Macs that require EDO (according to Apple), but upon
looking that up, it looks like it may only be DIMM based machines, so it
still wouldn't apply to this instance (where I said there were some that
required EDO 72 pin SIMMs).
So you are correct, it appears that there are no 72 pin simm based units
that require EDO, however, EDO is required in some Macs that use DIMMs
(which as everyone knows is NOT the same thing as SDRAM). Specifically,
the 4400, 5500, and 6500 require EDO... and the 7200 can NOT use EDO, in
fact there is a note saying it may damage the machine. The rest can use
FMP or EDO simms or dimms (according to the same chart, the 8100, the
system in question, wants FMP but will use EDO as FMP if EDO are
installed... which is consistant with what I have found of any other 72
pin SIMM mac I've upgraded)

Based on my findings, I've yet to run into a Mac that can't use EDO. Some
require EDO, but so far, all the ones I've played with that are supposed
to use FPM, work just fine with EDO instead. (note: I have never upgraded
an 8100, so for all I know, that could be the one model that really does
care).
Again, this is based on 72 pin SIMMs. It seems that Apple's 72 pin SIMM
requirements were pretty loose compared to their other memory
requirements.

Plain old cheap PC simms work fine. If you can, get non-parity as that
was what it really called for, but I have successfully used parity in any
mac I've tried (that require 72 pin simms that is... 30 pin ones will NOT
work with parity for the most part... there are a few exceptions like the
version of the IIci that was specifically designed TO use parity, as well
as IIRC, some of the last models to use 30 pin would work with either
style).
You should be able to pick them up cheap from enough places. One thing in
your favor... the Mac isn't very picky about matched simms, so you may be
able to buy a bunch from somewhere like 18004memory.com that sells
unmatched parts pretty cheap in their clearance section.

Hi.
I have a quad Qbus board in front of me. It is labeld "System Industries
9901-6082-A". It has two 40 pin IDC connectors, lots of TTL, four
AMD2905, three EPROMs, the usual PALs, ...
This is some sort of disk controler according to google. What I didn't
find out: Is this the complete controler or is this only a part of a
controler? There is a "System Industries 9900". It is a separate 19"
rack box containing a SMD (?) controler. It is interfaced to SBI or
UniBus or ??? with a bus interface card and ribbon cables. Maybe the
card I have is the QBus interface card?

Hi,
I am a happy owner of a IBM System/3. This system was standing unpacked
in my garage for more then 10 years waiting to be put back into service.
If was stored in perfect working condition.
Last week I started to restore my old IBM system/3 to working condition.
After solving several problems in the power up sequence the system was ready
to be IPL-ed.
Immediately I had a processor check. Checks lights indicated storage problems.
After investigation I discovered that the several X wires on the core planes where open.
These wires are mounted by IBM on a square frame. During a heavy forst period
(I live in the Netherlands) while standing in a unheated garage the copper
X wires shrink and broke. About 20% of the X wires are broken.
None of the Y wires (???).
These planes are stacked on top of eachother by IBM and the X/Y wire terminals are
welded together. This makes the planes non-accessible to repair the open wires.
I now have 2 unit (each 32k) both located in the system defective beyond repair
and idem a spare unit of 16k.
Any one who has such IBM storage unit available to bring my IBM S/3 back to live...?

Actually, the memory system in a VAX-11/750 are specific to that model.
It's not compatible with the VAX-11/780, nor the 11/730.
However, the memory backplane is compatible with the MK11 memory box for
the PDP-11/70. Unfortunately, the MK11 controller only deals with 256Kb
memory boards. So if you'd like to use these 1 Mb memory boards in an
11/70, you need a small hardware hack, and a small software hack.
The hardware hack is to tie four board select lines from the backplane
into to address lines for the memory card, and the software hack is to
reset all the ECC bits in the high 768K of each card, since the MK11
controller only clears ECC on the low 256K.
I have done both of these things on an 11/70 here in the past.

Thanks Tony,
If you already have it scanned, I would love a copy, however don't go to the
effort of copying it just yet if you have not already done so. I am unlikely

Btw, checked it over this afternoon and applied power - came right up and

In view of the temporal sequence, it seemed plausible to
ask whether Rand¹s work had any actual influence on Kay and
his colleagues at Xerox PARC. In October 2001, I sent
electronic mail messages to Kay, and to all the members of his
original Smalltalk team whose e-mail addresses were available
on the Internet, asking this question. The replies I received
were unanimous: Ayn Rand¹s epistemology was not discussed
by or known to any of them. Kay kindly sent me an extended

I just found a nice book that I'm sure a few people (Tony in the least)
would find interesting (if they don't already have a copy).
It's called "HP-41 Synthetic Programming Made Easy" by Keith Jarett. It
was published in 1982 by Synthetix. There's no ISBN but it does have a
Library of Congress Catalog Card Number of 82-62786. It's 192 pages and
seems very in-depth.

Has anyone played with the LVD SCSI to IDE bridges that Acard is selling
now? I'm trying to figure out if they'll sync down to the speed of the SCSI
bus that they're plugged into. I'm thinking about getting a SCSI-to-IDE
bridge for my VMS system which currently uses UW-SCSI. If it will work, I'd
just as soon buy a LVD bridge, as they're cheaper and will be better when I
finally upgrade my VMS system.
I'm tending to suspect they don't sync down, as they sell U-SCSI, UW-SCSI
and U160 LVD SCSI models.

Not very likely, though. I think Jim is more likely correct, that it's
a console cable or at least some sort of serial cable. The colours
Marvin mentioned are often used for flat cable; baluns are for twisted
pairs.
Also, serial cables commonly use a scheme where the innermost two wires
(4,5) are ground, either side are receive and transmit (3,6), and
handshake lines DTR/DSR (or DCD) (2,7) and CTS/RTS (1,8) are at the
edges. By that scheme, Marvin's cable would short DTR to DSR and RTS
to CTS, which makes sense.

Does anyone by any chance have a good 11/70 backplane that's surplus to
requirements? I've a couple of QED-95 boardsets(1), but no 11/70 this side
of the Atlantic to put them in... :-(
(I plan to build a tabletop 'ultimate 11/70' with the QED-95, modern
switcher power supply, Emulex SCSI, and internal SCSI disk... got all the
bits except the backplane!)
Alternatively, and even less likely, does anyone have a spare CIM-60 card?
This is the QED front panel interface card that's required to use the QED-95
with an 11/35 chassis...
Replies via email please, the list digests I receive are patchy at present -
they arrive all in a lump every ten days or so, with nothing in between!
(1) purchased on epay - latest one:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5149783592
Discussion point: this seller has had quite a few QED-95s recently, and also
quite a few Setasi PEP70/Hypercache sets. The PEP70/Hypercache consistently
goes for much more money than the QED-95 - up to $300-400 for a set, I've
seen. Anyone care to speculate why?

The description appears to be copied from the Lisa 1 currently up on
Ebay with a bid of $10K -

8223&rd=1 - suggesting that it's probably fraudulent.

Thanks for this information, Patrick.
I guess, I'll have to wait for such a VAX, I haven't one yet ;-)
Currently, I'm setting up my 11/24.
It comes with an RL02.
Yesterday, I worked on it a bit, checking grant and bus continuity, everything's fine now.
I found out the bootstrap adress for the RL02 (BOOT Proms are located on the Unibus Map Module (KT24)) and gave it a try,
with the RL02 disconnected.
No problems with typing in digits with the VT420 terminal.
This morning, the 11/24 apparently don't accepts commands from the terminal, why ?
On the CPU-Board, the CLK-LED is always illuminated, even when I press the Boot-button. Then, the RUN - und the PROC-LED
turns on for a moment, that's all.
Yesterday, when I typed in the bootstrap adress of the diagnostics-PROM, the 1 - LED turned on.
The 0 - LED always remained off.
Today, no typing in is possible.
When I press the boot-button, I obtain something like @000002
I need to know the meanings of the LEDs on the CPU-Board.
Can anyone give me some help ?
In the Maintenance-Card, the functions of the LEDs are described but it doesn't appear to be on the net somewhere...
Thanks alot in advance !
Pierre

Hi all,
Who can help me with a source for a timing belt for my IBM 5203 line printer ?
The old belt has given up after 13 years...
See: http://home.hccnet.nl/h.j.stegeman/IBMbelt.jpg.
It is a US sized belt:
Tooth pitch: 0.125" (1/8)" (this pitch size makes it hard to find)
Witdh belt: 0.500" (1/2)"
Outer length: 13 inch (98 tooths)
Thickness belt: +/- 0.080"
Finding this belt in Europe is hopeless, all metrical sizes.
Thanks for any reaction / tips that will make printer work again !
Regards
Henk Stegeman

Hi,
I received the following from a friend in France.
If anyone is interested in it, email me and I'll send
you his email address.
------- Forwarded message follows -------
...
While browsing my dad's attic a few days back, I stumbled on old Vectra and
MS-DOS manuals, ca. '86. There is the complete documentation set that was
sent with 286-powered machines, complete with MS-DOS 3.1 documentation,
plus a QuietJet user manual, and a few other items.
If you are interested, I can e-mail you a complete list.
The stuff is yours for the price of shipping.
If you are willing to pass this on to another possibly interested person,
that's OK. Otherwise, it will all go to my dad's trash can.
I've asked my dad to wait a few days [before trasking the stuff].

thanks,
Stan
I hate to use the CCList for this and I appologize in advance, but I can't
reach Roger at any of his 30below.com addresses. Every message I send
regarding the CCArchive List bounces.
At this point I can only lurk on that list because I can't post to it from
my subscribed email address.
Thanks.

Hi,
I've got a RAM march error upon power up. Does anyone have
a circuit diagram or information that can help me pin-point the
bad DRAM chip so I can get this old baby working again?

... has anyone had experience of repairing Belinea DH-1764 monitors?
It's a rather nice 17" monitor, but it has started losing width - the
image is *almost* right with the width set to full but then the
pincushion correction goes a bit funny. Cleaned up and resoldered
obvious dry joints which stopped the flickering. Dried up electrolytic
somewhere?
The original symptoms were a width-wise flickering *very*
intermittently, then one day I turned it on and the picture was a couple
of inches too narrow.

After hearing about the big earthquake and tsunamis that pounded the Far
East, I found myself wondering about one of my all-time favorite sci-fi
authors, Arthur C. Clarke. He lives in Sri Lanka, one of the areas that
was hit hardest, so I was snooping around the Web to see if I could find
any info as to whether or not he is okay. During my search, I came
across this real cool pic of him working hard on 2010: Odyssey 2. The
copyright date on the picture is 1984, so it is no surprise that a
couple cool classics would be involved. Check it out...

Uh, yeah, and none of his stuff has photos. You would think, if you plan
to get 4 grand for a computer that clearly condition makes a difference
in the price, you would post some photos. Ditto for some of his other
items.

A COMPLETE (including the manual, brochures, quick reference sheet, power
supply, and parallel cable) Votrax Personal Sound System is available on
eBay:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=162&item=5151487740&…
(I *WISH* I had all the peripherals that one comes with, with mine... It
even includes the custom parallel Y cable, which I still need to find the
wire mapping for and build... Speaking of which, I should get off my lazy
rear and finish building the power supply for mine first so I can see if it
even WORKS...)

P.S. sorry for the multi-send, comcast's mailserver seems to have some sort
of a rate limit against it by whatever isp classiccmp runs behind, so the
original message will probably arrive after the auction is over.
A few weeks ago someone (Sorry, I forgot who) pointed out a DSSI tape unit
available on ebay.
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5144248734
I bid on it, thinking that it would be phun to play with at a low price.
I won, and the unit contains a couple of old DDS SCSI tapes but more
importantly a CMD CDI-4000 SCSI/DSSI converter which appears from the SET
HOST/DUP firmware to be identical to my other CDI-4000 which does either
SCSI disks or tapes just fine.
Woo hoo! Score.
Thanks
Paul
I got this via email late yesterday:
?
"Would you know of anyone that would be interested in a DEC PDP11-34? We
just got one in stock and I can provide you with pix and a list of the
boards inside if you need."
?
So, if you might be interested in the 11/34 please let me know and I'll
put you in touch with the seller.

If you still have the manuals for loan, I'd be more then happy to scan them
in the mornings before school, I'd love to get copies of them and to do that
I'd be more then willing to scan them up. Comp teacher has a scanner I can
use in the mornings, so that's good! Heh, if you can, I'd love to, just laid
hands on a trainer that seems fully functional, and I'm looking about for
manuals, hard to come by on the 'net though ! :/
Hi, I know you were looking for these over a year ago. I have a source. Do you have a source for the small gear thats on the motor piston of a pc-2 printer ? I need about a dozen...Joe
Hello guys,
> > Can I use these boards in my PDP 11/24, too ?
> Nope, not if they're 7xx boards. If these are standard UNIBUS boards,
> you should be able to use them in both the 7xx and a PDP-11.
>
That's the info I found on the net from a 11/750 FAQ:
"National Semiconductor Memory Systems: 1Mb memory boards. These boards have
PWB 551109464-002 B
PWA 980109464-001 D
etched on them. They have a push-button switch for disabling the board, and a spare memory chip in a socket on the board. Board has green and yellow LEDS, which should normally both be on. Disabling the board causes the yellow LED to go out, and the red LED on the L0016 to come on, indicating bad memory configuration."
Fred, what do you mean with "very wide boards" exactly ?
These boards do have 6 fingers (hex wide) and fit into a usual UNIBUS slot.
What are the differences between the VAX11 bus and the ordinary UNIBUS ?
Can I find that out with a closer look to the pins ?
Pierre

I have a S-100 based system that seems to mostly run, but I have some
questions on the video card.
It is a Polymorphic Systems card, but looks different from all the examples I
could find on the internet
Markings are: Polymorphic Systems (c) 1976 I.P.C VIDEO? rev 0.0, with most
chips aligned vertically
The keyboard? port is a 14 pin DIP socket in the upper R.H. corner, next to a
8212 I/O chip.
Between this and the VIDEO marking, there are some pads with heat damage that
have the symbol for Zener diode across one of them. I have no idea what the
component specs are for these pads.
Also, 2 questions: does anyone have the DIP switch settings table for this
card? 7 switches, currently set at 1 1 1 1 0 0 0
and (2) the 8212 interface makes me think that the keyboard is some sort of
parallel interface, but the computer came with a DIP header connected to 3
wires
(bonus question: this card has some jumper wires and a resistor soldered on
the trace side of the PCB, is this official, or is this a hack? the joints look
sort of "hacky" the resistor goes between +Vcc and pin 20 of the 6571AL, the
jumpers are between some of the 74XXX gates on the L.H. side of the card
[where the 7805 V.R. is])
found it at my church garage sale several years ago, so I can't "ask the
owner"
