Anybody got the original install disks that came with their:
IIx – 6.0.1
IIcx – 6.0.3
IIci – 6.0.4 (has HD20 support in ROM/may not need the INIT)
IIfx – 6.0.5
IIsi – 6.0.7
The question of Hard Disk 20 support came up in this Compact Mac thread:
http://68kmla.org/forums/viewtopic.php?t=5240
And it was discovered that a special INIT was required to use it on these Macs that don't have support (the SE/30 & LC included). The MacIIHD20 INIT was discovered on a Developer CD from 1989 for use on the Mac II, but it failed to work on the SE/30 leading me to conclude there must be a modified INIT for the 68030 processor ROMs or at least one specifically for the SE/30. However, a developer note regarding a special INIT for use with the IIsi indicates that there would be an INIT for it as well. (the IIci was supposed to have support for the HD20 built-in)
The only way to be sure is to take a look at any INITs included with specific Macs install disks from 1988 through 1990 only (presuming all 1991 and later Macs shipped with System 7). The HD20 is NOT compatible with System 7, so if your II shipped with 7 it won't have the INIT – This is only for original CUSTOM System 6 disk sets that came with a particular II.
If anyone has their original disks to check or has experience using an HD20 with a Mac II, we'd love to hear from you!
FYI – I am expecting that these disks will be CUSTOM versions for each Mac, not the generic global install provided online at Apple. I would be very surprised if Apple shipped a generic system disk which could install software for any mac.
