I recently received a Lenovo Prodigy SE Accelerator, and successfully installed it yesterday. Then, I took the Lenovo Prodigy board out of my SE today. That wasn't really the plan.
The plan was to open up the SE and take out the floppy drive and bay so that I could install the PDS ethernet card; I can't live without ethertalk evidently. Well, I couldn't find an easy way to remove the floppy assembly, and gave up pretty quickly.
At the point I might as well try out my new Mobius 030 accelerator. No beep. No screen.
So as it stands now, it's just a regular SE with ethernet again.
