Summary
- If you are working with RS232 systems you will know how difficult it can be to get two different systems talking to each other.
- This is where protocol analyzers come in, and vintage devices like the HP4957A protocol analyser are now cheap on the second hand market.
- IMSAI Guy has one of these devices and in the video posted on YouTube he shows it off.
- The device sports a folded up chassis, a cute keyboard and a CRT-100 screen.
- Different protocol interpreters can be loaded to the device from ROM to RAM; it essentially acts as a dedicated terminal application.
- Modern devices might offer the functionality of these older devices but they lack the charm.
