Nein, er reicht nicht. Wurde die Erlaubnis ausdrücklich erteilt, oder ist die Erlaubnis eher metaphysisch einzustufen?

also doch der ganze text:
The fast development of computers allowed to think on applications quite early

The fast development of computers made it possible to think about applications quite early

The fast development of computers enabled me/you/xxx to think about applications quite early

think ABOUT
think ON is often said, but is regional (and archaic)
sounds odd

To "think on" could also mean weiter zu denken.

To think about s.th. is nachdenken. You could also use to "reflect on" s.th.

bergspinne: Noch besser kommt der Kontext in der Quellsprache, dann wissen wir wenigstens, was Du zu übersetzen versuchst. Ich rekonstruiere:

Die schnelle Entwicklung der Computer erlaubte es, schon frühzeitig über Anwendungen nachzudenken.

Die rapid development of computers made it possible to think about applications quite early.

How does that sound?

es gibt in diesem Sinne keinen richtigen Quelltext. Ich versuche den Artikel gleich in englischer Sprache zu verfassen.

Aber nochmal danke für alle Rückmeldungen. das gibt mir ein besseres Gefühl für den Satz

The fast development of computers made it possible to conceive of applications quite early

From the limited context, it seems that you are trying to say that thanks to the faster development of computers, it was possible to think of (better, to conceive of) something quite new, namely computer applications.

"To think of" means little more than to "have some thoughts about". In contrast, "to conceive of" suggests some original and remarkable thought about computers and what they can do.
