Just happened to come across an old post regarding the PCjr. Its
interesting that people still occasionally talk about it. I designed the
cartridge that you were talking about. It did reset the machine. This
was done to insure that the CPU didnt go into the weeds because of the
bus glitches. I (IBM got a patent on the little "L" reset tab on the
card edge. There is also a mechanism where the cartridge actually
replaced the on-board BIOS.
