[Test-Equipment] W&G PS-19 CPU board

[Gollum]

Hello everybody,


    I have a W&G PS-19 with the CPU board of the new type, with just 2 EPROMs.

See this picture :

You will notice that one of the two EPROMs is missing

I found a CPU board of the old type, with 6 EPROMs of lower capacity.

My question is : are the two, at the edge connector level, equivalent ?
Can I put the old board in place of the new one, that with the missing EPROM ?

Or better yet, does anybody have the missing EPROM image he can send me
as a file ?

Thanks,
