The jack on the front is RF output.

When a 128 boots up it will attempt to 'boot' whatever disk is in the
drive. A boot disk isn't necessary unless you want to use the CP/M mode
of the 128.

To boot the 128 into 64 mode hold down the Commodore ket as you turn it
on, release and you will be rewarded with a 64 bluescreen. Otherwise it
will boot into 128 mode, either 40 or 80 columns depending how you have
the 'columns' key locked.

Only for CP/M.. It's a good version too!

Only in 80 column mode, the 128 has an RGBI port for that. If you have
no color RGBI monitors you can always fasion a composite monochome cable
by connecting to pin 7 (monochrome) and pin 1 or 2 (ground) to an RCA
plug, that pin was designed for monochome composite output.

The best (low cost) configuration is to have the 128 hooked up to the
1702, with the 40 column split/composite & audio plugged into the back
and the monochrome 80 columns in the front. The quality of video using
a proper (split composite) video cable in the back of the 1702 is
excellent, I highly recommend it!

No. Unless you like chipping away Epoxy resin.

That is Kickstart 1.2 allright. Kickstart 1.3 or later would be better
because they have hard drive autoboot coding and 2.0+ is more compatible
with recent Amiga software.

I have the 1.2 Workbench and Extras Disk around here somewhere... :)

The hard part would be getting it on the right format of floppy...

Yes and no... Yes, there are plans for hooking up Macintosh 3.5" floppy
drives to the Amiga, BUT, they are used only for the Macintosh Emulators
for the Amiga (BTW the Amiga 500 can run a Mac Plus Emulator at just
about speed.)

Recap, I have the Amiga Disks and also have a split-composite cable to
hook the 128 to the 1701 (for the best 40 column output).
