Universal JTAG Adaptor

This adaptor was originally intended to allow programming of the memory and CPLD of the PSD813 used in the GBECG Gameboy cartridge, which converts this games console into an electrocardioscope (see October 2006 issue). But it’s much more universal than that (see box entitled ‘In-Circuit JTAG’) Our adaptor connects to a PC parallel port and uses the JTAG IEEE 1149.1 protocol.
