Mac II Series Original Install Disks

Mac128

68020
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.

As far as I can tell from my disk/manual sets, those systems came solely with "stock" System Software disks. I cannot find an HD20 Init on any of mine, Systems 6.0.1 through 6.0.8.

Yes, they shipped generic install disks that could be used on any Mac. At the time, system software updates were 100% free, so the copy of 6.0.7 you got with your IIsi could happily be used on a Mac Plus. (Well, that may have been a bad example, since the IIsi came with HD disks... But you get the point.) The installers on all of my 'system-shipped' System 6 disks include the "Minimum System for xyz" for every machine that was available up to that time. So, yes, my IIsi-shipped HD 6.0.7 disks do, indeed, have an option to install a Macintosh Plus system.

 
They did that for a while - System 7.1 was never free, yet my LCIII System install disks still have the option to install on any Mac prior to 1993, including the Mac Plus.

 
Was there ever a System Install CD with System 6? I know the IIvx was the first Mac to have an internal CD-ROM drive and that shipped with 7.1, but externals were around since the IIx.

If there were no "extras" disks that shipped with these systems with custom applications and no CDs which might contain those extra goodies we came to expect from Apple, then I am hard pressed to know exactly how Apple distributed this mystery INIT, except by dealer only.
