I thought I'd mention, do use caution when fixing pulse generators. The output transistors are often mounted an a beryllium ceramic. Even the dust from these is quite toxic. These usually have warning stickers but stickers can get lots. Dwight

For most all TTL, except some bus drivers, one can use a pulse generator to override a 1 value to inject a signal in a circuit path. Most don't realize that these have many uses.
