A4000T not giving video output from my Cybervision64 Card

[patrik]

@Vlabguy1:

1. There is no video output part of the motherboard, which the CV64 depends on in any way.

2. As you have a 060-card, you MUST install the 68060.library correctly, or else the OS3.1 will think you have a 040 and try running it with the 68040.library. This is NOT supplied with OS3.1, and there should be a disk bundled with your card containing this.

As 3.1 does not know of 68060.library, there should also be a "dummy" 68040.library with the 68060.library on the disk, which should replace the Commodore 68040.library. Its only task is to load 68060.library when the OS asks for 68040.library.

So in short - there should be a disk bundled with your card, containing two files called "68040.library" and "68060.library". Just copy those two files to LIBS: and reboot.

If the 68060.library is not correctly installed, much will act wierd and it is very very possible that the graphics card will be affected.

3. Does the monitor you have connected to the CV64 remain in powersave mode or similar when selecting a CV64 screenmode with Prefs/Screenmode, or is it "active", albeit with a black picture?

patrik,

1. Makes me feel much better now that it might not be the motherboard. Thx.

2. The 060 files are in the correct place, but perhaps not..I will check double
     check then tripple check.
     I will check to make sure the 060 disk that came with the card is all OK.
     Thx..I didnt even think of that
3.  I will double check that as well..but I believe the monitor stayed in
     powersave mode.


Thanks again for everyones input and keep it coming!  Solving this hopfully
minor problem can save someone else a headache later on down the line.
I will post further info and any and all results.

Thanks again
Rich

I just wanna say for the record....I got it all working.  It happend within 15 mins, it was amazing! dispite anything I have said this was simply great, the amiga rocks!

a big thanks to all who help.  I have earned sooo much in the past few months, maybe one day I will get a hang of this stuff.

@pierre

Care to share how you solved the problem?  

I don't know how many times I've read threads about somebody having a problem, a bunch of people offering advice, and then a thanks (or not) is offered with no explanation as to the solution to the problem?

[Vlabguy1]

Yes please share how you did it??

thanks
Rich

[pierre]

so if I install this 42.7 driver I can I just install bb2 with the rom update?
thanks!

[Vlabguy1]

@yogisumo..

No worries ..I will post all my results..tomorrow when I solve this prob. of mine.
I will be working on for as long as it take this weekend..and I hope that by the
afternoon I should know more and have it fixed, yeah boyee..unless ofcourse
it turns out to be my motherboard.in which case I will be one BUMMED out man.

Take care everyone!!

it's NOT the motherboard, I am willing to bet money! those things are sturdy. Please belive me, IT'S NOT THE MOTHER BOARD. Can't be, it's imposible!
I will post what I did once I get some time.
thanks again,
Pierre

[Vlabguy1]

Thank you Pierre for your kind words...and I look fwd to hearing what you did once..

Peace2everyone

pierre,

Well here is the bad news...  I took my CV64 card out of my 4000T060 and
put it in a 4000Desktop.  Installed cybergraphxV4(fresh install) with the pass-
through cable hooked up and the output from the CV64 going to my Idek 17"..All
worked well..upon reboot the cybergraphx logo came up ..then the standard
Amiga mode came up with Workbench(OS3.1)..all is well.  I selected a CV sscreen mode  ..and it worked..no problems no issues.  This tested the monitor
and the card all that used to be hooked up to my 4000T...
So I took everything out reinstalled the CV64 card into my tower..made sure I
did not have any old versions of cybergraphx on the HD of the 4000T..I did
a fresh install of the cybergraphixV4(oh just so you know I had the pass through hooked up as well, and worked fine)..I used the same options as I did when I installled the software on the Desktop..well the software installed just fine
well when I went to change into a cybergraphx mode..the screen goes blank..
I get nothing.
When I do a reboot I get nothing..not even a standard amiga screen through the pass through.
I think my motherboard is toast!!  Anythoughts..
I also check all my ports on the back of the computer..and it seems that I have a loss of -10v and +10v on my serial connector??  What is that about?
Is there anyway I can get pinouts for ports of 4000T which shows voltage details..and also..a Zorro 3buss pinout.adn possibly the CV64 ouput pinout..
I will soon test other cards..scsci, Retina, toaster, etc..
My only alternative might be a Cyberstorm PPC with the graphics card option?
Could this be a powersupply issue?

Im bummed out to say the least..
Well there is the update!!  The not sooo good news..
Take care and thanks
Rich

Patrik,

If and when you get a chance check out my lasted post regarding this problem..

Thanks

As I said earlier, it sounds very wierd that it should be a hardware issue, when it worked before the OS reinstall.

Anyhow, it is also very wierd that it wont work on your A4000T.

The fact that the CV64 is found working, and recognized by CyberGraphX (else no screenmodes would appear), suggests that if something is wrong, it must be a very minor fault.

The only hardware-issue the A4000T generally suffers from is that the powersupply connectors to the motherboard can overheat, so you should inspect these for burnmarks. If you wont find any, they are fine.

Some things you should try though are:
1. Do a "list LIBS:68#?" in a CLI and verify that 68040.library just is a few kB in size, much smaller than 68060.library.
2. Try another CPU-card. Don't forget to set the INT/EXT (should be marked with "I" and "E" and numbered J100 and J104) jumper-pair correctly, it depends on the CPU-card. C= A3640 (stock A4000 040) needs them set to EXT (E) and C= A3630 (stock A4000 030) needs them set to INT (I) for example.

Patrik,

Thanks for the info.  I will be honest with you regarding the Powersupply connetctor issue, is that the machine prob has a total about 50hrs on her..
and NEVER left on for any period of time unless I was useing the machine.
but I will check the connectors.

Could the fact that I have a -12v/+12v loss on the serial connector have
anything to do with anything??

Im trying to locate a set of schematics for the 4000T motherboard..as well
as all the appropriate voltages for every connector on the back of the machine
including the CV64.  

I can and will try the org. CPU card and I will also verify the 040.lib

thanks again and will keep everyone posted..I will be trying other
video cards as well ..
Oh here is another thought..Has anyone heard of ploblems with the
A4000Ts A/V module..ie leaking caps..could this module have caused
some damage or is damaged..I will check to see if mine is ok..
So why do I have a loss of 12v..on the serial connector?


Peace and take care
Rich

Hmm.. you should check the PSU directly. If I remember correctly, A4000T uses normal AT-PSU (pinout available for example here: http://pinouts.ru/Power/MotherboardPower_pinout.shtml)

If you have the time, you could also use that A4000D hw with your A4000T: boot up your A4kD with CV and clean working install you did before. Copy workbench.library from your A4000T LIBS: to LIBS:. Remove from your A4kD CV, HD and processor-card and put them in your A4000T. Remember to set jumpers (INT/EXT) to same positions you were using in A4kD. Turn the machine on and check if things work now.

If it turns out to be hw-problem, which I really doubt (except for that PSU), there is still no need to totally lose the hope. You can contact these two helpful guys, Anthony Hoffman from amiga.serveftp.net and Jean-Jacques Boulet from www.amigacenter.com. If breaks some day, they can fix it! :-)

[Vlabguy1]

quenthal,

Yes I will check the power supply..but do you think that has anything to
do with the CV not giving me an output??  and or anything to do with
the loss of +12v/-12v??

Thanks.
Rich

[quenthal]

I'm not sure, but if CV depends on 12V-line and it is not supplied in zorro-slots your symptoms could very well be caused by that. Zorro-slot pinouts available here: http://www.l8r.net/technical/t-zorro.shtml

P.S. You could also try that other way to check things out and report here.
