In this episode, we see two memory cabinets from the Q7 (Little Memory). It appears as though the core stack was removed from at least one of the units.
On the right side of the lab, we see sections of the Duplex Maintenance Console (DMC), with the TV monitor and signal generator in the center section, as in the Time Tunnel. To the doctor's left is a Simplex Maintenance Console (SMC) panel. In front of the doctor's legs is what appears to be a Manual Drum Tester panel.
In the future, Irwin trots out a lot of his toys. From the left, we see a Burroughs B-220 console, two Burroughs B-200 series tape drives, sections of the DMC, another tape drive, more DMC sections, another tape drive, the right hand section of the SMC, two more tape drives, and another B-220 console.
Inside the Spindrift, we see a section from one of the logic frames, with some light strings added.
Inside the Spindrift, we see a Little Memory cabinet posing as a nuclear reactor. Behind the cabinet are the logic frame sections, again.
Inside the Spindrift again, 3 sections of the DMC, with a metered panel in place of the smaller TV monitor that was seen in The Time Tunnel. This appears to be the same unit from the right hand side of The Time Tunnel.
The right hand section of the SMC, with some extra panels from the left section added on the lower right, under the test generator panels.
On the left, the DMC section from The Time Tunnel with the large TV monitor and signal generator. On the right, part of the SMC.
A Manual Drum Tester panel, as used on the Seaview's diving chamber.
