I have a Mega ST4 (Tos 1.4 UK) with an internal ICD micro ST host adapter and (brand new, empty) 80 meg seagate (1096N??) drive set to SCSI device #0. Now I want to add an SH205 (with data on it in a Mega box) to this configuration. The device drivers I have are the one from ICD and some archaic version of atari's device driver. Is it possible to use these harddisks at the same time? What software is needed? (I would prefer a solution in which I don't have to open my computer to alter the ID of the internal drive.)

ICD do state that the only way is with some form of parrallel connection of Ataries acsi standard. Iam not to sure what they ment by this.. -- *** Roger W.

The ICD Micro adapter (both the AdSCSI Micro and the Advantage@< Micro) actually change the DMA mode when they are installed; non-ICD host adapters are not compatible with this new mode for the ICD Micro adapters. Now the ICD Advantage and AdSCSI have what is called a "dual-mode DMA"; it supports and converts between the standard DMA mode common between most Atari and Atari 3rd-party host adapters, and the mode supported by ICD's Micro adapters. Have I lost you yet?! =^) It really is not as complicated as I make it sound. You will just have to put an ICD AdSCSI between the external DMA port (on your Mega), and your SH205. The ID number on your internal drive (inside your Mega) can stil remain the same, you can still use ICD's software. Good luck and take care, bye.................... Luis

I'm just dropping in here again in this thread to ask; PLEASE : can _anyone_ give some idea where I can get hold of ICD/Supra/ Berkley Microsystems/Brand X Hostadapter manufacturer or suppliers who stock their stuff?? Either here in Oz, or indeed anywhere in the world! Thanks (I hope) Matthew

I am trying to attach a Mac external SCSI drive (Quantum 105S) to the SCSI port on the back of my Supra 30MB Atari Hard Disk. I'm using the 1988 Supra Software and Host Adapter and it doesn't have the format parameters to handle a Quantum 105S. Also, when I plug up the disk to the external SCSI port, the Quantum 105S is online but the system never recognizes its presence as device 1, LUN:0. I've swapped the 105 and the 30's mechs and the 105 functions fine, but it seems that even after removing the SCSI terminator on the 105, both drives are not working in conjunction. Does anyone know if the Supra Host Adapter of that era can handle the Quantum? Also, if I get an ICD Host Adapter, does that end all of my problems? And finally, a friend told me that I should use Atari's HDX Formatter for my extended partitions because it is the only one supported. Is there some incompatibility between Atari's extended partitions, Supra's and ICD's?

Hi Charles, As soon as you can, call Quantam's Technical Support and ask them for the format parameters for the 105S; and while you have them on the telephone, ask them to send you a technical reference manual for the 105S (Supra's software will let you enter the parameters manually if you know them). Remove the terminator resistor pack from the first drive in the DMA chain (the Supra's drive) only; leave the terminator resistor pack in the last drive of the chain. Set the Supra as device #0; then the Quantam as device #1, 2 or 4 or any device # that the Supra software will recognize the Quantam. Depending on the mechanism that the Supra is using, you may have to switch the device numbers around. Now about extended partitions under TOS. As far as I know (and I could be wrong, somebody please correct me if I am), BGM (or extended TOS) partitions are the same regardless whether it's Atari's, ICD's or Supra's; at least I have had no problems with the three (and I use all three of them). If you do want to use BGM partitions though, make sure that you are using at least TOS 1.04 (1.4) or higher. So long as you are going to use Supra's software; I would also recommend using PinHead and Diamond Cache. Take care, bye.......... Luis
