I took two digital photos of my NEC PC-8001 expansion chassis. My previous description of the unit was incorrect. The disk drives are housed in a totally separate chassis. The actual expansion chassis contains a slotted backplane so that expansion cards may be added to the PC-8001. The first picture shows the dual disk drive cabinet atop the 8012A I/O Unit. http://www.siconic.com/crap/8001exp1.jpg The second picture shows the inside of the I/O expansion chassis (sorry about the glare...this stupid camera doesn't have an option to turn off the flash correctly, or stupid me forgot how to do it right). You can see a RAM card plugged into the lower slot. http://www.siconic.com/crap/8001exp2.jpg The I/O unit has an external connector that the PC-8001 plugs into. It has a second connector that plugs into the disk drive unit.
