Making a few B&W LAI XY Vector PCBs


Recommended Posts

I am going to make PCBs and Monitor adjustment board for the 20" B&W XY LAI Chassis (LAI-KZ-20XYB)

 

Pot board is designed

 

It will mount on the bracket that holds the heatsink

And a copy of this

Pots board include

  • X Gain
  • Y Gain
  • B Adj
  • Brightness
  • Contrast

 

I need 4 or 5 of these

Let me know if you want one :)

This has been promoted to active. Starting to convert to pcb file ready to make the required Gerber files

 

I am about a week into it, nothing too taxing about this one I must say. :cool:

Hmmm, I have an upright Asteroids that I would like to keep running in good condition for as long as possible, it's fine ATM, but for $30 to help future proof it I think I would buy one of these. I'm assuming it plugs in as a daughter board and takes over from the original adjustment pots?

 

Hmmm, just clicked on the pic, that looks nothing like mine, I don't think mine is a LAI, I got it from Visy who imported it from USA, too tired to research tonight :sleep

Your's will be Atari, LAI's will have the family logo on the marquee and the sideart

Still going on these

 

Starting to add the top layer silk screen, and have decided to add the values of the resistors.

 

The 14" screens had some different values, so I will think of a way to allow for that (Maybe add a key/legend on the board, you can refer to when assembling)

I won't be doing a prototype, just a main run, as the tooling cost is high. Might do a run of 10 to 15 of them only, I think

that looks familiar........hahaha

 

Yep, I will still use your creation mate

 

I am working on a proto that uses the HV from an amplifone Colour, and the deflection from the LAI board, so yours is the contender for the job

So you could feasibly use a regular colour TV Tube in a BW vector game

More IDs done now

 

Notes done as mentioned earlier

 

Different type of triangulation used on a few transistors so they are soldered in more stable

There are a lot of components on this sucker. I have removed about 12 components not needed on the 14" or 20" and added a few aftermarket pots too. They could be preset X & Y size pots

 

We will see

That looks spot on Dez! I have never had a board made with an angled side (or anything other than a regular rectangle for that matter).

 

Was this an issue? Did you have to specify anything or just supply Gerbers with an angle on the edge?

All I did was "place polygon", then right click the shape and select "define as board outline"

 

Here is what it looks like on the gerber viewer

So the PCB maker will see the angle correctly, and should be cut like that
