Universal JTAG adapter
Next simple board in “universal” series is JTAG adaptor. First was Universal USB adapter with power supply. Most commonly used JTAG connector is 20 pin IDC, found on many prototyping boards. It takes lot of board space and requires through hole drilling in PCB, which I usually avoid when building prototypes with single sided PCB, manufactured with toner transfer method.
This simple adapter has all neccessary pullups and pulldowns. Connector at one side is standard IDC20, at the other side are 9 pads in line with 2,54mm raster.
