Just got a loaded system--questions

[gto69ra4@aol.com (GTO69RA4)]

My local dump provided the most complete Apple II system I've ever found:

1st gen Apple IIe full of cards
Monitor III with stand
Set of Disk II drives
Apple Dot Matrix Printer
Kensington System Saver II
Sider II hard drive with card
Apple Keypad IIe
CH joystick
Lots of original manuals and software, and...

An unused 4 MHz ZipChip with manual!

Now, I have a couple questions. Is there any advantage to keeping this IIe
instead of loading up my Enhanced IIe? I can't think of any. Also, does anyone
have some instructions on using the Sider? It boots to the menu and seems to
work, but I'm not really sure how to use it. Formatting, managing data, and
booting into the CP/M mainly.

Thanks
