By now I know that the A590 and the 2091 are logically identical apart from the "XT-interface" in the A590. But what is it? Is it ST506 or ESDI? Or even EDI(?) as I've seen some people call it. I need to know, 'cause I would like to buy a larger (preferrably cheap) drive to replace the 20MB Epson in my A590. (I find large SCSI:s too expensive :-( I know all about the differences between ESDI, ST506 and SCSI and the different types of ST506: MFM, RLL, ARRL and so on, I just need to know which type the "XT-drive" in the A590 is! Also, is it "half-height"? My *guess* is that it's half-height, ESDI, 3.5". Any help would be much appreciated. Michael -- Michael Bergman Internet: d88-mbe@sm.luth.se // Undergrad. Comp. Eng.

Did I miss it...? I take it this EDI thing is rather common, or..? Also, could any of you guys give me some prices? Let's say for a drive of around 100 MB suitable for the A590.

I think you are missing an important point here. The A590 will accept a SCSI hard drive as easily as it accepts the IDE drive. So, for your 100 megabyte hard drive, just grab a standard 105 Quantum and a 2 inch long standard SCSI cable. Plug and go.

Plug and go. How is that so. Does it actually have two different controllers in it? BTW Please excuse my ignorance... I'm not even quite sure what the A590 real purpose in life is so if the answer to this question seems obvious to most, then consider me a dumb dumb in need of an answer :-). srm -- Scott R.

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.

The SCSI controller on the A590 also works with SCSI tape units (at least with my Wangtek 60 Meg SCSI) and uses the same tape backup software that the 2091 uses.

OK, you've convinced me the A590 is great. But I don't need to buy a box, board, and drive. I have a drive. Can I get the box and board without the drive? Or just the board and I'll make my own box around my drive. I am definitely interested but my interest drops rapidly if I have to buy the whole thing. Perhaps someone has a used one they will sell at a reasonable price? Dana Bourgeois @ cup.portal.com EMail OK!!

As long as we are talking about the A590... I managed to get one at a cut rate price only later to find out that it had a rough life in its previous home. The A590 I have has got the following: AWK 312618 REV 7 512k expansion RAM (120 ns, CMOS) Epson HMD 755, IDE type Hard Drive The problem is that my Amiga 500 will not function when the memory is installed. The memory is installed properly. No problems with the chips sitting the wrong way. The 512k jumper IS set. As soon as I turn the A500 on it just sits on a light grey screen. No request for Workbench, no blinking power LEDs, nothing. I'm not expecting any miracles.... but perhaps a little insight into whats happening with my A590. Thanks, Jason
