    Yes, you could mount more than one system in those cases. I had about 30 Advantech rackmount systems that had 15(?) slot backplanes and the backplanes were divided into two sections. You could run a separate CPU and I/O cards in each section. The power supply was common as I recall. Several of these system had HP-IB cards and each computer was linked to the other one in the same case by HP-IB!
