What made the box notable was floppies in the crate

box and only a LED (power on) on the front pannel. It was one of the early
turnkey systems and became popular with applications/system integrators
for that reason. The reason being it was now possible to sell a small(then)
system that was powerful enough to be a complete office accounting system.
It didn't hurt that the wood cover fit into office decor of the time.
The wood disappeard when FCC started forcing RFI constraints.
There was a good reason for that. A friend had purchased one of the
Integrand S-100 boxes with a floppy cutout. He'd installed an SA-400
(IIRC) and complained that it wouldn't work reliably. What I
discovered was that the field from the large power transformer was
playing hob with the drive electronics. I installed a substantial
steel shield around the floppy and the problem abated.
When I purchased my own Integrand box, I opted for the drive-less
model.
Even on the Durango box, we had to shield both the drives and the
small monitor that sat over them to get reliable drive operation.
