My company has a couple old Tektronix TLA704 logic analyzers, which aren't bad for data capture, but the display program is pretty doggy.
(It's an old PC-compatible mainframe, running Windows 95 in 32M of Ram)
Tektronics has ceased support on it and the only way to upgrade it is to swap the mainframe (a costly process, I'm sure). This would be nice, but for the amount of time we use the device, and for what purpose, this might not happen. I plan to at least upgrade the software to the last supported version...
I'm curious if anyone has done a Linux port to this mainframe. The tough part would be to get information on interfacing to the capture card. It contains a TLA 7M4 module.
Linux does a better job in the constrained environment than the latest Windows, and would probably run quicker.
