I have been out of the hardware scene for a while.
While getting up to speed, I have noticed that the "SimmSticks" seem to be insanely popular.
Perhaps I am just missing the obvious - however, I have some questions:
- Many Simm sockets have a minimum life expectancy of 25 insertions. After that you are on borrowed time. Has anyone noticed a problem in this area during prototyping?
- I don't see what the spectacular advantage is over using the little .100 single and dual headers and stacking the boards together. Back in the day (> 10 years) this was *the* method we used for Z80 and 68HC11 boards and I/O.
If we were protyping, we let friction hold them together. For permanent use, we fastened them together with standoffs.
- Lastly, in this modern day of space travel and microwave ovens, why hasn't SPI or I2C become the bus of choice for uC projects. No backplane required, few wires, almost unlimited I/O address range...
I'm probably doing a lot of point missing. Cal C.
