I have an Atari Megafile 60 which is filling up fast. It is possible
to expand this without shelling out all the money for a second
megafile 60? Specifically, can I simply add another drive to the
interface in my current Megafile?
Here are the details:
- my drive has the number SEA{something} on the back. Someone told
me once that this meant it was a Seagate drive.
- ratehd tells me that the adapter is an Adaptek {something}
I know that I could expand things by purchasing another megafile and
chaining it onto the DMA, but is it possible to expand the one I've
got now, say from 60 meg to 120 meg, by adding another drive
mechanism to the current controller? Physically there seems to be
lots of room in the megafile box.

It is possible, but you have to do several things with the Controler-
board ! But I don't know, what you have to do...
But it is possible..
please notify me, too, when you get more Information..

The Megafile board has both the acsi and the scsi boards on one big board. They left the connector for the second drive control cable off, but sucking out the solder and putting one in is probably pretty easy. -- John Henders jhenders@jonh.wimsey.bc.ca Vancouver,B.C. or jhenders@wimsey.bc.ca or ubc.cs!van-bc!jonh!jhenders

Pin 17 and pin 18 of the second drive control connector are connected to ground, which makes reading from the second drive impossible. You have to clip off one resistor, leading from pin 17 to ground, and remove the connection of pin 18 to ground on the lower side of the controller motherboard. You'll also nead special driver software that's aware of the second drive. AHDI won't work. I don't know if the ICD driver will help you, but I think you'll at least have to patch it because it looks for special ICD hardware before running. My driver (CBHD) knows about second drives and works with all kinds of ACSI hard drives I know, including Megafile 30 and 60. ---------------------------------------------------------------------- Claus Brod, Am Felsenkeller 2, Things.
