Help with pin outs of various circuit boards & drivers

Hi,

I have been working with lasers on and off for over 30 years, but mostly off for the last 10. so I thought it was high time to start playing around with a few of the bits and pieces I had lying around. To fill the gaps in my army of optics etc I bought a couple of lots on eBay of some scanner and drivers boards, haven't we all! But the problem is the guy I bought these from has no technical details of them. So can anyone really help me out. The boards come from the following companies:

1) Cambridge Technology
2) Chameleon Technology
3) GM Technology
4) Laser Electronics Ltd
5)Laser Grafix S+H Ltd

I have included some pictures below, sorry about the lousy quality, if you need any better ones I can see what I can do

Attachment 33309 Attachment 33310 Attachment 33311 Attachment 33312

This, I think, is a G120D scan amp, but am really quite unsure it may be to drive a GM20. It is labelled as being made by Laser Grafix, with the actual assembly being done by Prosol electronics

Attachment 33313 Attachment 33314

This one is marked as being made by Chameleon Technology and I think it is a scan amp for CT6800 or similar. But it does have DMX beam Card also written on the board. As you can see from the photograph most of the board is unpopulated and it has very few components in place.

This, I believe is a GM20 actuator driver board. In fact this and the 1st card come in an instrument case together to drive a number of GM20s and a couple of G120Ds. Although it does not show in the picture it has printed very faintly on the boards "Actuator Driver V2". again it it marked as being made by Laser Grafix

Again another board from Laser Electronics Ltd, it is marked as being "CT Drive Card Issue1

Attachment 33319

This card seems to be a dual galvo driver for CT6800 series galvos. It is marked as being made by GM Technology Lighting and just says "High speed galvo" on it. It also has 2 additional connectors, one marked "servo", 2 pins and the other "shutter" again 2 pins

Attachment 33320 Attachment 33321

The next one is a Cambridge Technology driver for CT6800 and is marked CB6580 Rev 0, which I hope may be quite straightforward.

Attachment 33322 Attachment 33323

The final board is a power supply board for 24v actuators and galvos, I am told it can also use a 5v TTL signal and drive 12v actuators or solenoids, but have no evidence of this. Again it is made by Chameleon Technology and marked as a "Galvo Power supply".

Sorry for such a long first post, but I am eager to see if these plus other bits I do have info on can help me build my first projector in over 15 years. Any help is really appreciated!!

thanks

Steve
