[net.micro.mac] Can Switcher Leave Home and Find True Happiness with Hard Disks?

cordy@utai.UUCP (J.R. Cordy) (06/28/85)

It appears that Switcher simply doesn't work with my Davong external hard disk.
At first I thought the apparent lack of support for hard disks was simply a 
minor oversight in Switcher 2.0 which would be fixed in later versions (that 
seems to be what the Switcher 2.0 documentation implies).  However, I have now
received (thanks, Apple!) Switcher 3.5 and it still seems to have the identical
limitation.

Now, there's nothing strange about a Davong hard disk - it uses AppleTalk in
what seems to be a legitimate and standard way to communicate with the Mac, 
as I presume other external hard disks must do also.  So what's the real story?
Does any version of Switcher work at all with external hard disks?  Am I doing
something stupid, and it actually does work with Davongs?  True facts and
other useful knowledge is solicited.

For those at Apple (and Davong, I suppose), if you haven't heard of this 
problem before (surely, you MUST have), here are the boring details:

	Machine:	512kb standard FatMac, no mods.
			Davong MacDisk hard disk attached to modem port.

	Software:	System of May 2, 1984,
			    updated using System Update of Apr 15, 1985, 
			    with Davong drivers installed using
			    Davong MacDisk Install Drivers of Jan 17, 1985.
			Davong MacDisk Volume Manager of Jan 16, 1985.
			Finder 4.1.
			Switcher 3.5.

	Symptoms:	Switcher fires up, runs.           
			First application usually installs fine, sometimes
			will run for a while.
			Shortly thereafter, at apparently random time (theory:
			when AppleTalk becomes active?), Mac goes catatonic 
			(mouse ignored, cursor frozen) and must be rebooted.
