I keep it under a plastic cover to keep dust out when I'm not playing with it.  Yeah, it's not a great machine compared to my Altair 8800c or my IMSAI-JAIR or my IMSAI Z-1 or my Sol-20 that I'm slowly repairing and have to make my own cabinet for it as I only got lucky to get the main board and S-100 backplane.  But all these machines use old out of date chips and they all have a lot of chips in common.
