Last OS *my* 68000 Mac Plus has run is MacOS 7.1.
MacTracker
claims 7.5.5, I can't dispute that as I haven't tried it but I expect
it might not do much good (no RAM left for applications). Same is
claimed for the Mac SE and Classic and PowerBook 100. MacTracker
doesn't report the Outbounds (Jeff?) but since (I think) they used
motherboards from the above systems,
The Outbounds used motherboards designed and built by Outbound but
with Apple ROMs installed which were scavenged from Apple Macs.
I can't speak to the Notebook series but the Laptop (a much cooler
machine, IMHO) will not run past Mac OS 7.0.1. However, this is a
limitation in Outbound support.
In order to use the Outbound Laptop Model 125 one needed to run a
system installer application from Outbound after installing the stock
Apple System. The Outbound installer definitely puts some code on
EEPROMs living in the Outbound Laptop. It may also do some
modifications to the System file, but I'm not sure about the latter.
It also installs some custom Outbound inits (control panels and
extensions, now days), for things such as power management and the
trackbar control.
Outbound went under before or pretty simultaneous with Apple
releasing 7.1 so the Outbound installer was never modified to support
7.1.
The required modification could be very simple from a programmer's
point of view but I've never been willing to invest the time to
figure it out. I'd have to develop the skills to interpret 68000
machine code in the Mac OS environment and for the Mac Plus-ish
hardware and figure out what's going on and that seems like a
daunting task when there are so many hardware projects around.
Still, if there are any 68000 savvy programmers out there interested
in taking a hack at it, it would be cool to get the Outbound Laptop
past OS 7.0.1. The jump to 7.1 would be very nice.
Additionally, the Outbound Laptop is an interesting beast in that it
uses 2.5" IDE hard drives. This is the first Macintosh to use an
IDE device by many many years. I don't think any Apple Mac used
them until the Quadra 630 and its performa and LC cousins.
Anyway, the Laptop only supports up to an 80 MB drive. I suspect
that it just has parameters for four drives stored in the installer
(20, 40, 60 & 80) but I don't know for certain. It would also be
very nice to hack the thing to support larger hard drives.
Have you tried to find 80 *MB* hard drives these days? Of course you
have; this is the CC list. It's a pain. I had a line on a place
in Florida with fifty or so in stock for about $40 each but didn't
have the money at the time and now they're gone who knows where.
Sigh.
Anybody have the modified Macsbug application? The Outbound Laptop
required a patched version of Macsbug.
Also, the Outbound Laptop was meant to dock with it's host computer
(the desktop from which the ROMs were taken). There was a card that
installed in the host and provided teh connection to the Outbound.
I've never managed to find one of these cards. I envision Pluses
and SEs going to scrap or being sold without the owners ever
realizing this very rare card is installed. Scrap is especially
likely because a Mac with the docking card installed won't boot up
unless the Laptop is docked (ROMs required). So the host machine
would appear "broken".
