Tek 500 pulser modules

[dwight]

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.

Hi
 I thought I'd mention that when troubleshooting a computer, if you can't takeover the execution of the processor, such as a diagnostic ROM, a pulse generator can be a useful tool. 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.
