[net.micro.mac] 512K System Disk

khj@ecsvax.UUCP (Kenneth H. Jacker) (03/22/85)

   My Apple dealer included a new "System Disk" marked "512K" along 
with my memory upgrade.  Comparing sizes between it and the 128K
"System Disk" showed that the 512K version is ~500 bytes larger...

   At first, I began copying the 512K version to all my 128K disks.
Later I thought I should try booting one of the 128K disks on my
new 512K machine.  It worked fine!

   What I'm wondering is exactly what is different between the two
"System Disks"?  I see that "Imagewriter 15" is new, but what
about the actual "System" file?

   Any help will be appreciated ...
