IIX doesn't boot, only green screen

2007-04-16 by Hans Nijhof

Hello,

after connecting the communication cable from the keyboard to the 
mainframe, with the power on, my system doesn't start up anymore 
(static electricity). It only shows a green square on the monitor and 
the keypad of the music keyboard doesn't show any text at all. I've 
checked all the fuses on the back of the mainframe, they all are OK. 
Also disconneced the music keyboard and plugged the qwerty keyboard 
directly into the mainframe. Also no effect. I can here the diskdrives 
running when I put in the boot disk, but nothing changes on the screen 
or keypad.
Did anybody else have experience with this problem? Are there also 
fuses on the cards inside the mainframe? If not which card could have 
something to do with this problem?

Thanks in advance

Hans

Have you tried to load a sound to see if the disks
are still working? Place a disk in the drive and then
hit 1 and then * on the keyboard keypad and see if
anything happens with the disk drives.
 The monitor may be a different situation all
together.

The machine hasn't been moved. What happened was, I booted up, page 
1 appeared, then I noticed no responce from the keypad (LED) and 
qwerty keyboard. I saw that the communication cable (which isn't the 
orignal, so without the locks) had left lose from the other 
connector. And I pushed it back in the connector. At that moment the 
screen went green and no Led's on the keypad. I tried some different 
kind of boot-ups, but no succes. Also waited a day. I haven't tried 
to load any sounds, because I thought the system wasn't responding. 
It's an idea to try this, to figure out what's still working.

Has the machine been moved since it was last in operation and how long 
since the machine was last used?

hi Hans,

That must be terror. 

One thing you should never do is to reattach a connector while
equipment is running, some pins may become connected before others do
for one thing.


My suspicion is this:

- the cable has a loose wire and is causing a short in the cable. Use
a voltage meter and test whether any pin connects to more than one
other pin (or open the connector you plugged in again and visually
inspect).

- Unplug the plug that came loose and see whether the monitor comes
back online.


You can mail me in Dutch directly.

Regards and good luck,
Harald.

Re: IIX doesn't boot, only green screen

2007-04-18 by Hans Nijhof

Hello Kevin,

thanks for co-thinking.
I've booted up, it stops after 20 seconds, so that looks OK, then I 
inserted the sounddisk the drive starts turning. I try to load a 
sound, but no result at all. Also tried to change to another page, 
but then I don't hear the system disk. So it seems that everything 
what has to do with input/output communication doesn't work. So no 
monitor, no music keyboard, no A-N keyboard, no keypad.
Is there a card that holds this job?

Re: [Fairlight-CMI] Re: IIX doesn't boot, only green screen

2007-04-18 by Laurent Lemaire

Hello Hans,

I don't know if you have some spare parts or access to another
Fairlight in working condition... It would help a lot.

The way I would do the analysis... I would unplug all the useless
borad which are not needed to boot an OS9 floppy. Yes, you can
boot OS9 on a IIx.

So the cards that have to stay are the following one:
 Q256 - Q133 - Q209 - Q219 - QFC9

Please refer to the following webpage for their descriptions :

http://members.tripod.com/kmi9000/kmi_cmi_hard.htm#hardware

Then if your CMI still doesn't boot, you will need to swap boards
with another one to find out which one(s) is/are dead ...

If you need an OS9 boot floppy, I can provide one.

Hope it helps.

    Laurent.

Are all 3 power supply LEDs on the front panel on?  I understand that
you checked the fuses, but perhaps a power supply failed without
blowing a fuse.

Also, when you say that you hear the disk drives running, do you just
hear the disk spinning, or do you actually hear the head seeking
across the disk (the chunk-chunk-chunk sound)?  All the drives need to
spin is power, but seeking requires that the CPU be running.

IIx is running again (was: IIX doesn't boot, only green screen)

2007-04-19 by Hans Nijhof

Hello again,

I'm glad to tell that my IIx is working again. Just like Joe 
mentioned this was a power problem. I said that I checked all the 
fuses. Well I checked them on the back of the mainframe. But after 
opnening the mainframe I also noticed two on the board at the back of 
the box. They were OK. And in the housing of the boards behind the 
Frontpanel are also three fuses, and one of them -12V was broken. 
After replacing it, the system booted up.

I want to thank all who did some co-thinking. Especially with these 
old machines, where a lot of technical knowledge gets lost, we can 
solve some problems by helping eachother.

Wow, glad you're back up and running.
After hearing about your problem I finally took the initiative and removed
the batteries from some of my real-time clock cards to prevent leakage.

Best regards,
Harald.

Re: [Fairlight-CMI] IIx is running again (was: IIX doesn't boot, only green screen)

2007-04-19 by Glenn

Very glad Hans got his machine working again. Very cool that the collective minds helped get him there. I didn't know what to suggest, but for what it's worth i want to offer/share something else too. Recently my entire apartment/fairlight nest was filled, as i slept and was awakened to nausea, with the most noxious, toxic and disgusting odor imaginable - something like rotten eggs only worse. After opening all doors and such for ventilation and standing outside waiting for it to clear up i was able to sniff it down to one place: the 133 CPU board's battery(same part IIx and III). No leaking there luckily, but man it stank! It turns out when they go bad they can "breath" this gas out and seeing as how the Tadiran 1/6th D cell 3.6 volt TL 5135/P's (digikey.com and lots of places sell them) are all getting on in years (they're only supposed to last 10) though i'd mention this for the benefit of anyone whom hasn't already changed theirs to get in there and do so (just know how to solder/desolder and don't the the battery get too hot or anywhere near water or moisture and dispose of properly) so they don't have to go through the stinky-room effect:) Seriously, you can change it after but why not pre-emptively change it first?

Best regards,

glenn

Hi Glenn,

I think you got lucky in one way that you smelled the onset of bursting..
I figure you desoldered them already ? I have a damaged card that was
eaten away partially by that stuff. The battery disintegrated and came
loose from the contacts. I should upload a picture to scare y'all :-)

I did not install a new battery, I can type the date and time when I boot
up, no worries there. A small effort to save my Q133 from digestion.

Best regards,
Harald.

Re: [Fairlight-CMI] IIx is running again (was: IIX doesn't boot, only green screen)

2007-04-19 by Glenn

Hey Harold,

went to OSH (hardware store ) bought what looks like a wildly large hazmat helmet with a plexiglass faceguard and gloves. Warned my neighbors to stay inside in case it "blew":)(hey there are all those people whom got killed when their cell phone batteries blew and this thing's at least as big as that), but if they'd seen me desoldering in the hallway in that getup...:) Still have yet to replace the others but will this week, to preclude the stink and "digestion". Good move on your part finding it when you did too cause it sounds like it's still working, right?. Guess i was lucky but what a nightmare. At first though a rodent had crawled under something and died, then though it had crawled in the CMI and died, so in a way it was a relief:)

If anyone wants to replace them they only cost about 8 bucks plus shipping and there are no variables.If you look up the part you may be confused as i was seeing part numbers that end in /p /s and they're all the same. It's a holdover from when they used to have a version with long pins and one with short ones. for about 7 years they've been only making one kind (shorter pins, but long enough for your fairlight) and shipping it under both part numbers, i guess to make it easy for people that are already ordering parts on a regular basis with the old part numbers. The lady i spoke with at tadiran in new york was very sure and added that if you did you find one with the long pins it would be 7 years old min, out of a 10 year life. So i got the new ones and they're fine.

Basic stuff on soldering/desoldering if anyone's going for it and unsure about that (but basically use a temperature controlled soldering iron station - $70-ish USD at radio shack but make sure you get the extended warranty because I've had 3 die- about 725 degrees is good, "tin up" the tip of the soldering iron by feeding 60/40 solder into it till it's shiny and wipe it periodically on a damp sponge, you don't want to leave the tip/heat on the solder pads for too long or they'll lift just long enough to feed a bit of solder into the hole as you pull away gently on that part of the batter from the other side then repeat around the 3 pins until it's out then feed solder into the empty holes on the pc board and right after hit it with the soldapullt and you should end up with 3 shiny new looking holes, ready to have a new battery pushed in an soldered into place,

Lots of solder and flux makes slowly pulling out pins one at a time and desoldering holes easier, and use a large "Soldapullt" instead of solder braid - always) to desolder, wear eye and or face protection, be careful, make sure the ventilation is good. Also break off pieces of solder around 2 feet long to use because if you leave it on the coil as you use it it can suck all the flux out of the rest of the coil and mess the rest up if you want to use that later.

Sincerely

glenn

Hey guys,

Where (on which board) would that battery be located on a IIx?

The words "CPU CONTROL CARD" are easier to see on the card than "Q133" which is written in super small type on mine, the card has 3 ribbon cable receptacles too. The battery is relatively huge, a cylinder the size of 1/6th of a D size regular battery. You'' probably see it right away.

The battery is also usually purple on top.

I have not verified this, but it is said to be in slot 16.

I renamed the thread.

Regards,
Harald.

Found it. 

Is there any special care I should take while removing it. Can't find
anything in the service manual about replacing the battery.

It looks ok though on the board. (no leakage)

Cheers,

Don't know what the book says, but outside the book, normal computer safety considerations, be careful of static.But wear protective eye gear at min, if you can get an anti-static wristband that plugs into the wall (to connect your wrist to the ground on your outlet by way of a 1 megohm resistor) for about 10USD, best to handle electronics that way, no cats or dogs, no shuffling on a carpet to "shock" a friend and then forgetting and instead working on the Q133. I put some tips on desoldering in a previous post,but mostly from the opposite side of the pc board, touch the already heated and "tinned" solder tip to one of the leads and feed in some solder, pushing the lead just a touch in whatever direction has the most room to move, at the same time, pull up just a bit on that part of the battery, then repeat as you move around the pins until the battery is a good ways out. At some point you'll feel that it's safe to pull that side of the battery to where one of the pins is all the way out, then the next and so on.

Central ideas:

don't heat the pin or the trace(pc board) or the battery too long, as briefly as possible.

don't try to get the solder out of the holes first. That leads to disaster. Adding solder helps gets what's in there flowing and that's what you want to gradually work the leads out of the holes without applying force (force also can lead to disaster). Once the old battery is clear (and needs to be disposed of appropriately because its poisonous and explosive) then even apply more solder to the holes, then use the a large Soldapullt brand (my suggestion - they're reliable) solder sucker (not the braid) to suck it all out of the holes, use some flux remover to clean up the pcb around there (don't breath those solvents though or get them on your hands) and wella! the board is read to receive a new battery which can then be easily soldered.

if you have ANY trepidation about soldering, (or maybe even otherwise) I strongly suggest practicing first (it is an art) on some crappy old computer motherboard or VCR or scrap PCB from a surplus house something until you've got the hang of it. Get your chops up.

Way better to do that (solder is cheap) than mess something important up.

Batteries are about 8 USD.

A lot is redudant, but hopefully helpful

Hi Glenn,

Thanks, I suspected there was some soldering involved :o(
I'm more a software guy. At the moment I'm trying to figure out a way
to use the apparently spare pia to tranfer MDOS disk files from and to
a PC......

Might it be an idea/possible to place a battery socket or something
like that on the board. I have an ensoniq DP4 which basically had the
same problem (fixed battery) and a common "fix" is to replace it with
a socket. 

Haven's seen this type of battery here in the Netherlands....

And ehm, what is this battery supposed to do anyway? 

Cheers, 
Patrick

I had to do a lot of soldering during education, so I know I'm not
really good at it ;-)

PIA or ACIA are for periphiral interfaces. I'd prefer the ACIA (rs232)
but for now I read in the service manual that one of the ribbon plugs
on te Q133 should be connected to a spare PIA.

It's rather preliminary, but if I'm correct it should be possible to
rig a plug to a PC com port and do file transfers from and to MDOS
diskettes. The goal is to offload my rather precious sound library to
a more reliable storage medium, and to facilitate exchange of files,
for instance through this forum.

what is "spare pia?? i don' tknow what it does but it's there for a reason:)(someone said date and time) so i'm replacing instead of just removing.

don't worry about the soldering, just go by the stuff i wrote out, practice removing parts like soldered in ic's, from some throw away electrics item first and you should be fine. Happy to answer any and all soldering/desoldering questions but offline cause don't want to torture the list any more than necessary:)

It's not a commonly used battery. Lucky they still make it, really.You can order this part online from many places. You can start with Tadiran.com and then find distributors in your area from their site, or just do a search for "Tadiran" TL-5135/P or/s

Again they're not much money. Got mine at Digikey.com( phone 1-800-344-4539, Part number 439-1024-ND) they were very nice when i called to confirm), can't remember if they were one of them, but some places have a minimum order or a charge if you're not above that there are plenty that will sell you one inexpensively. You might be able to rig something of a socket up but i'd talk with Tadiran about that because it's a weird 3 pin in a triangle shape format. Figure i'll only have to do this once a decade so just soldered that puppy in.

Sounds cool. Wonder too if anyone been using CMI explorer or CMI os (different programs?), which SCSI adapters have worked well with, the SCSI Compact flash interface, the series III alphe keyboard workaround, adapted lightpens on a IIx, etc and willing to talk about their experiences, parts/model numbers, plans??

Come to think of it, it might also be possible to "abuse" the midi
interface for this purpose. Then no hardware would be required. 
Just have to find the MDOS entry point for  it, and it would only work
for IIx with a midi interface I guess.
