300 Series Keyboard & Display Test

Test and exercise all keyboard/display units from the 300 series. Malfunctions in these units can mimic logic box failures, so it’s useful to be able to verify that the keyboards and displays are working correctly.

300 Series Core Address Decoder and Driver Test

All calculations and intermediate results in the 300 series are stored in core. Core matrix addressing and core drive are provided with multiple #510 logiblocks and any failure here will stop the machine. It’s useful to be able to verify the decoding logic and measure core drive strength.

Dedicated pages for these tools, with images and construction details, will be added as they are built.
