A couple of months ago someone posted about a ram test procedure for
the Midway game boards that involved AFAIR grounding a pin on each of
the ram chips and viewing the result. I cannot now find the post or
the RGVAC doc from which it was derived.

Can anyone point me in the direction of the post or the RGVAC doc.

Thanks

Peter
