The A590 is an add-on for the A500. It gives you a 20 megabyte (IDE) hard drive, sockets for 2 megabytes of fast ram and a SCSI controller with a pass through. You can add a SCSI hard drive(s) to the thing by way of the external SCSI port (extra power supply needed) or you can open the thing (see "warranty-voiding operations"), remove the IDE drive, insert the SCSI drive in its place and connect it to the internal SCSI connector (no extra power suppply required.) There are one or two DIP switches on the back of the A590 that need to be taken into consideration but it's really cake. It just seemed that you were getting the wrong impression - that the A590 used *only* IDE drives. Not so. In fact, the A590's SCSI controller is a close relative of the A2091 controller and it is *fast*. bj > Scott R.
