Q&A

What caused the glitches in the vintage Apple IIe?

The glitches were caused by a faulty RAM chip, specifically part UF7 on the motherboard.

How did Colin determine the faulty chip?

Colin used the self-test feature of the Apple IIe and identified the second chip from the right as the culprit.

Why did Colin replace the wrong chip initially?

Colin mistakenly interpreted the self-test results due to the different chip order listed on the screen and the motherboard.

Why did Colin choose to install a socket rather than soldering the replacement chip directly?

Installing a socket allows for easier chip replacement in case of future issues and maintains period accuracy in repairs.

How did Colin verify the legitimacy of the replacement RAM chips?

Colin conducted a simple test by scrubbing the top of one chip with alcohol to ensure that the markings remained.
