trancor northern, oscilloscopes

I just saw some rack mounted oscilloscopes out on the loading dock. They are manufactured by trancor northern, and have a quad height slot available from the rear of the unit (no cover for the slot). It has a dual height LSI11 cpu board (DEC), and another dual height board installed(DEC). The second unit is the same, except the second card has generic white handles. Does anyone know about these things? one rack has two of these, and under them is a dual 8" floppy drive unit, that has a small ribbon connector that connects to something via a 25 pin rs-232 connector. There are various oscilloscope probes there as well, with BNC style connectors to connect to the oscilloscope. I didnt count, but i'd say roughly a dozen probes mounted on the outside of the rack on some custom made holder. -Lawrence LeMay
