OOH kie dokie then
Well I retract my last report on the capacitors. I believe these are a foil axial lead type and what appears to be a blown out end on one side just may be their normal construction. There are four of these on the Logic board. Also what I thought was discolouration from blowout was just a little tarnish on the leads, there are no black or burn spots on or near these capacitors anywhere and their soldered joints are clean.
I think the only next thing to try are the removable DIP ROMs themselves and to try and obtain the missing one. Anyone have an ideas where these may be found? In the manual all four are noted to have some control over the CRT.
Thank you so much
Rick
