I heard a rumour (nothing more, nothing less) that the Atari Hard disk drives don't use the reset pin from the DMA port. Is this true? Anyone care to comment. ------------------------------------------------------------------------------- "I think all right thinking people in this country are sick and tired of being told that ordinary decent people are fed up in this country with being sick and tired.

Is this true? Anyone care to >comment. It's my understanding that the RESET makes it to the Host Adapter board, but doesn't go any farther than that (i.e. it's not passed on to the SCSI controller). I believe that this is not unique to the Atari HD. I think it also applies to the Supra host adapter too. I don't know about ICD. I think BMS is the only one that passes the RESET to the SCSI controller. It appears though that Supra does some special things on RESET. -- David Beckemeyer | "To understand ranch lingo all yuh Beckemeyer Development Tools | have to do is to know in advance what 478 Santa Clara Ave, Oakland, CA 94610 | the other feller means an' then pay UUCP: ...!ihnp4!hoptoad!bdt!david | no attention to what he says"

Hi, The ram disk chip uses it, and it is passed on. I'd assume that all controllers would use as it seems to be quite easy to hang the protocol. I have off-loaded distribution of the ram disk chip to a company called Ronsat Technologies, (312) 520 8003. They will be making a complete ram disk package etc. They are located in the U.S. Glen Stone (I'm moving CA, and will be off the net for a while. My new job does have net access so I will return )
