Is there a reason a Silicon transistor/diode wouldn't work here? I'm assuming it either has something to do with voltage sensitivity or frequency, but older computers like this tended to use fairly high (TTL) logic for signaling.

Ah, ok I get it now. My eyes somehow completely skipped that paragraph.

Brother, this system predates the concept of TTL by quite a fair margin.

I will proudly confess I am not well versed on the history of EE :)
