I have finally gotten around to wiping my slow and unreliable Power Mac 8600/250. It just has bits of old software here and there such as unused extensions that case the system to take nearly 10-15 minutes to boot and slow in general. It is easier at this point to simply wipe and start again, keeping some of the important programs such as Rumpus and Office 2001 on a USB stick to be transferred over once OS 9 has finished being set up. So here is what gave me pause. I of course formatted the old SCSI 4GB HDD before I reinstalled the OS, but I had to choose between Mac OS Standard and Mac OS Extended. I know the differences between to two quite well, so that is not what bothers me. What does concern me is: If my system is primarily Mac OS Extended, and it is the Hub of my AppleTalk/LocalTalk network, will this cause trouble with old systems seeing it on the network? e.g. 512Ke, Classic II. These systems can only use OS Standard ff course. Now usually my PM 8600 was always Mac OS Standard, but because it was 4GB, it blew the minds of any Pre-System Macs I had. To get around this, I instead hosted a 120MB Mac OS Standard Image from the 8600 and they could then access that without an issue. SO in conclusion, having selected Mac OS Extended as my main HDD File System, will I be okay to share to other old devices on my network as long as I continue to use a Mac OS Standard image as I have done so in the past?
