[sdiy] Old Motorola parts ID

[mirwin at qouest.net]

Hey John, Jim, Roy, Phil..

Thanks for the replies. The 1975 Motorola Linear databook does not 
mention any of these devices. However, an IC application book by J. Lenk 
 from 1973 mentions that the MC300 and MC304 are Motorola ECL chips... 
so maybe the MC351G (to MC360G inclusive in this batch) are also ECL. 
Didn't realize that ECL went back that far, but Lenk says early RTL 
chips were available in 1960-1961.
Regards, Mike
BTW Roy, apparently  there was a huge amount of interest in tunnel 
diodes when they became available, they were the fastest semiconductor 
devices around, but they have some very severe power-handling 
limitations and drive requirements, vacuum tubes still outperformed 
tunnel diodes in microwave applications and transistors soon surpassed 
them at UHF. Tektronix apparently used them to advantage in their scope 
trigger circuits.
