"The Datapulse Model 108 Pulse Generator is an all solid state, high quality pulse generator combining functions previously unavailable in commercial pulse generators.
The instrument feature clean, high power pulses, high duty cycle capability, fast rise times, and high repetition rates. Coupled with these features is the capability to generate clean, wide, low power pulses at low repetition rate. The 108 is designed to perform most pulse applications conveniently and with the utmost reliability." (Datapulse, Manual 108, 1964-1970)

The Datapulse 108 is a full transistor pulse generator launched about 1964. Unfortunately Datapulse wasn't able to gain form the solid state design, as the overall construction is typical for tube equipment - large and heavy. Datapulse was taken over by Systron-Donner in the late sixties. From that time Sytron-Donner built it's famous line of smaller instruments. My 108 manufactured in 1971 has the late Systron-Donner front panel layout. The '68 catalog mentions a lead time of 10 weeks, more than all other items - maybe the model 108 was only assembled on request.
The restauration of the 108 which I bought from a surplus dealer was very easy. The never used instrument was wrapped in foil and still sitting in it's original container! Even the Datapulse quality control tag was in place. You can imagine: getting some new-old-stock parts or even instruments is like christmas day!
