The 5150 also had covers for unused drive bays, and filler brackets for
unused slots. Both of those are pretty common.
The TRS80 had a cover for each cable port. The only one of those that is
commonly still around is the one for the RS232 port. In FPUIB last
year, I had had a handful of those unused, still in the plastic bags.
There was also a cover that went over each port WITH a cable.
