I am still troubleshooting an Apple II+ that appears to work fine w/o periphreal cards but gets wonky video when cards are in and no life in the cards.
I started doing some simple non-invasive assessments. I discovered I have 2 chips that are getting significantly hot compared to all other chips, one is Apple ROM E0, the other is an SN74S195N.
1) Is this normal for these chips?
2) I have heard about DIY ROM replacements by burning your own on an EPROM. Anyone done this and had success?
