an old analogue eclipse

[zinzi]

Dear members of this forum

 

I'm looking for some technical information about an old analogue zero 88 desk, a 60 channel Eclipse. We have one at our school but it is broken down and I am trying to fix it. But there are some problems with the programmable parts. The chaser module and the two preset modules can't work together, I guess it must have something to do with the jumper settings. I hope you can give me some advice to help me on my way.

The Eclipse was a bit before my time, I'm afraid, but I will ask around and see if I can find out some information for you

Hi

First a word of caution.

While checking modules and ribbon connections ENSURE the keyswitch is OFF, as any disconnection or connection of any ribbon cable can cause massive failure of the electronics.

 

If memory serves correctly

The first thing to check is the "Master start up" link .

On the memory panels (IE large panels nearest operator, excluding Grand Master) where the 40 way ribbon connects to the CPU board there is a link. I think the silk screen on the metal back box indicates it. The desk will only operate correctly if one and only one of these links are made. no link or 2 links are bad.

 

When this is correct power up into program or run mode and check that there is only one preview light on at a time across all memory panels.

 

The master link can go in any panel as long as they all have the same number of channels. If you have 60 channel memory panel and a 72 channel the link MUST go in the smaller.

 

 

Hope this helps

thank you for your reaction on my question .

How can I find out how many channel a memory module has :?:

Hi

the only real way is from the software numbers on the Eproms.

 

Depending on the age of the system some where numbered xxxx-60 for a 60 channel etc.

or if a bit older just the xxxx, you would need to give me the software numbers to look up number of channels.

 

Or if you are lucky and the memory modules have their original labels on the front they may say 60Ch 72Ch 120Ch.
