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.
- tsomctl 8y ago> Diodes this old when put on a curve tracer can sometimes look more like a resistor than a diode.
- Posibyte 8y agoAh, ok I get it now. My eyes somehow completely skipped that paragraph.
- that_jojo 8y agoBrother, this system predates the concept of TTL by quite a fair margin.
- Posibyte 8y agoI will proudly confess I am not well versed on the history of EE :)
