Perhaps there were other ways to see whether there was activity on the bus, but I was thinking of having a scope that was useful for the 8 MHz bus speed. Yes, they existed. On the other hand, they were not affordable for most people.
And yes, memory was expensive back then. I remember spending several hundred dollars to get 16 MB in 1992. That purchasing decision biases my computer purchases to this day. I still over provision RAM after reaping the benefits of it over 30 years ago.
- bogantech 3y agoBack in those days you'd check for activity using a logic probe, cheap and simple. People don't use those much any more because we're spoilt with our cheap scopes
- gorkish 3y agoThere are a number of ways to probe a data bus for the presence of a signal. You don't need a scope capable of fully characterizing it to know it's there. And furthermore it wasn't difficult or expensive to get ahold of a 10 year old scope in the 90's; it just took slightly more effort.
