Zorro I Expansion Chassis
external upright case which provides two Zorro I slots - one is occupied with the 2 MB RAM card
the slots are not buffered
connects to the A1000 side expansion port
passthrough connector to allow other expansion be attached to the side port
optional external power supply (9V/1A), required for using the 2nd slot
power LED indicator on front panel
Notes
the memory board in slot 1 generates clock signal for the bus and is required for the second slot to be compliant to the Zorro standard
second slot could be used to add another Escort 2 RAM board (4 MB FastRAM in total), or to install an ST506 controller card - Escort 2HD
if ST506 controller is used, the 5.25" hard disk is mounted in an external upright case of the same size as the Escort 2 chassis
installing a second 4 MB board requires cutting 3 jumper links on the board
