Title: A500 and scsi through side conn.
Post by: chsedge on March 23, 2006, 09:22:10 AM

I've an accelerated a500 (derringer 030) and a first edition '91 scsi controller attached to the side slot (zorro 86 pin).

I put my machine into a tower and build scsi cables to extend the short original to my device (the original quantum disk drive). My question is: how many devices can I attach to this controller?
Is this a SCSI compliant controller? Or it drives only one device?

If not which are the best controllers around to get at least 2 devices on?

;-) I'm not sure of the particulars of that controller, but in general there can be eight devices on a SCSI bus.  Mind you, the controller itself counts as one of them, so you're left with seven drives, scanners, etcetera to add on.

Each device needs a unique number between zero and seven.  (Seven is usually the controller itself, but not always.)

Also, the appliances must be connected in series, with no "Y" branches allowed.

;-) It should be.  Just remember to terminate the bus at each end, and no where else.  Of course, some controllers have termination built in so that you needn't worry.
