I have a Defender that works fine except for an all red background. It has been narrowed down to the CPU and is NOT a monitor issue.
I want to replace the SN7489N at 2C on the Defender CPU to see if it fixes my red issue. However, I don't have one handy, nor another Defender CPU.
I do have a Stargate CPU with some corrosion issues around the battery area. Will the 74S189N at 2C on the Stargate board work on the Defender board in the same location?
