Hi,
thank you for this excellent repository of AHT info!
I would like to suggest to add a line about MacBook1,1 - AHT 3A104.
The file is here: http://download.info.apple.com/Apple_Hardware_Test/018-2393-A.dmg

I have just tested the file and it works fine with a USB stick on an old MacBook 13.3" (first series)

I would also suggest to point out in your readme that some old DMGs from Apple website have to be converted with Disk Utility before use (at least on High Sierra).

Many thanks and kind regards,
Mattia
